Carbohydrates: include sugars and their polymers. They include monosaccharides disaccharides, and polysaccharides. The monosaccharide is a monomer, the disaccharide is a polymer,and the polysaccharides are macromolecules.\n \nMonosaccharides: The basic formula (CH2O)\nExamples: triose sugars, 3 carbons, glyceraldehyde and dihydroxyacetone; pentose sugars. 5 carbons. ribose, deoxyribose, and ribulose; hexose sugars, 6 carbons, glucose, galactose, and fructose.\n     \n\n \n \nDisaccharides: These are double sugars with the formula C12H22O11. Notice that one molecule of water is missing from the formula. The covalent bond holding the two monomers together is called a 1-4 or 1-2 glycoside linkage. Examples: sucrose = glucose + fructose. maltose = glucose + glucose, and lactose = glucose + galactose.\n \n     \n\n \nPolysaccharides: The basic formula is ( C6H10O5)n . These are macromolecules capable of acting as structural or storage molecules.\n \nStorage Polysaccharides: Starch is a plant storage polysaccharide that is composed entirely of glucose joined by @1-4 glycoside linkages. amylose is the simplest form of starch. amylopectin is more complex and is branched. Glycogen is an animal starch stored in the liver and muscles of vertebrates. It is more highly branched than amylopectin.\n \nStructural Polysaccharides: Cellulose and chitin are examples of structural polysaccharides.\nCellulose is the most abundant organic compound on earth. It is made of glucose, like starch, but they differ in the type of 1-4 linkage. Instead of an @ linkage as in starch cellulose contains a B 1-4 linkage.\nThis causes the polysaccharide to take on a step arrangement and not a linear one like in starch.\nEnzymes find it difficult to brake the B 1-4 linkage.

If you want me to use those specific terms it sounds like you're going to just copy what I write for your assignment.  I'd be happy to explain the process to you, by I'm not going to write your homework paper.\n\nThe idea is that plants produce food using energy from the sun, and all other life either directly eats plants or eats things that eat plants.  So all life (except some protists, that, like plants, can make their own food) lives on energy that the plants have harvested from the sun.\n\nI hope you already know what the laws of thermodynamics, photosynthesis, and respiration are.  If not, pay more attention in class or look them up on Wikipedia.  You should be able to figure out how to phrase the explaination in a way that uses those terms on your own.

Photosynthesis produces oxygen by combining CO2 and H2O to make glucose and O2. Cellular respiration (what plants do at night and what animals do) takes glucose and O2 and makes CO2 and H20. The answer is C.

The human machine has three major sources of input energy: carbohydrates (bread, grains and simples sugars such as those in milk and fruit), protein (meat, legumes) and fats (too many kinds to name). When the body consumes one of these energy sources, the food molecules are broken down into smaller pieces using enzymes--doing so releases the stored energy in the food and provides small pieces from which to build more complex molecules. \n\nEach food source has a specific role to play in metabolism. Carbohydrates are the dietary source of an important sugar called glucose. In fact, carbohydrates, such as the starch in potatoes, are simply very long chains of connected glucose molecules. Glucose is so important because it is the only source of fuel for the brain, red blood cells and several other tissues. Your brain uses about 120 grams of glucose per day. Any carbohydrate consumed in excess of what is needed for running the body's basic metabolic processes is converted to glycogen or fat for long term storage.

During cellular respiration (how we turn food into energy) O2 is the final electron acceptor. BUT... the O2 is actually turned into 2 molecules of water, so the carbon does not just hop onto the O2. The CO2 comes from the breakdown of carbon-rich sugars and fats in your food. Example... Glucose has 6 carbons...as your body rips carbons off of the glycolysis products, each carbon combines with 2 oxygens to become CO2...so 1 glucose yields 6 CO2.

Photosynthesis does *not* produce carbon dioxide. Photosynthesis uses energy from the sun to combine CO2 and H2O to make glucose. Respiration breaks down glucose for energy and gives off CO2.

carb:\n1. basically, carbohydrates have carbon, hydrogen and oxygen. the ratio of hydrogen to oxygen is 2:1\n2. rice, starch subtances like potatoes\n3. carbs are for energy\n\nlipids:\n1. also carbon, oxygen and hydrogen.. but the ratio of hydrogen to oxygen is more than 2:1\n2. butter, margerine, oil\n3. also as extra source of energy.. lipids can be a heat insulator of the body\n\nproteins:\n1. carbon, hydrogen, oxygen and nitrogen are the main elements... other element which may be found is sulphur...\n2. beans, peanuts, meat, milk, fish\n3. proteins are something like the building blocks for our body to grow...

You mean Ethanol. In the upper mid-west of USA it is corn (cool climate). In tropical(hot) climates it is sugar. Both require much heat (energy) to reduce or change the product into ethanol.

Combustion reaction is when a substance reacts with oxygen to produce carbon dioxide (sometimes is carbon monoxide) and water. So for the disaccharide (C12H22O11) the reaction will be:\nC12H22O11 + 12O2 ----> 12CO2 + 11H2O\n\nSynthesis Reaction means combining the chemicals given in the reaction. Oppositely, dissociation is the breaking down. So for your examples, the answer is 2KCl and 2HI.

Carbon dioxide, because that is the raw material required for photosynthesis

The answer is (D) simple sugars.  However, cells must break down glucose through cellular respiration (glycolysis or fermentation) to create ATP, which is the energy molecule used for cell processes.

Hello friend.. \nHope you have heard of chlorophyll and other colouring (pigments) agents naturally present in plant leaves.Chlorophyll is the chief chemical helping reactions that finally end up in production of starchy food in plants. \nThese chlorophylls themselves break down and  are being continually used up in the food-manufacturing process. \nBut while the plant grows the plant resynthesizes this pigment and  leaves seem green.\nBy the end of  summer, cells called cork cells, which are degenerate products, get accumulated in the base of the leaf-stump. This results in blockage of water transport to leaves through their "veins".  Chlorophyll from then on degenerates and breaks down. \n    In the fall (autumn as we call it here), seasonal changes slow down the rate of  chlorophyll-synthesis.\nCarotenoids which are another group of pigments present in leaves become clearly visible through these leaves devoid of Chlorophyll. Light is not needed in order for a plant to produce carotenoids, therefore these pigments are always present in a living plant. Aspen, Black Cherry, Sycamore,  Maple and  Poplar are some of the trees famous for their pictureque beauty in Autumn. Carotenoids appear in colours ranging from Brown or red to yellow depending on its concentration in these leaves.  Examples of carotenoids found in leaves include lycopene, which is red, and xanthophyll, which is yellow.  When found naturally, carotenoids give colour to carrots, beetroot, and a number of plant and animal produces like mango, banana egg yolks etc.\nBesides these natural Carotenoids, there are a group of pigments called Flavanoids that appear in the leaves only during autumn. Examples of flavonoids include flavone and flavol, which are yellow, and the anthocyanins, which may be red, blue, or purple, depending on pH (strawberry, apple,  cherry etc..)Anthocyanins are the chief agents among these flavanoids. They are a result of degeneration of sugar moieties in leaves. In autumn, as a plan to prevent losing precious minerals, ions and vitamin-enzymes through falling leaves, these chemicals are transported into the trunk/stem of the plant. But Carbohydrates, being complex molecules aren't transpoted to the main stem/trunk. The transport of ions back into stem causes a  fall in the phosphate concentration in the leaves,which in turn triggers production of Anthocyanins. This process is dependent on physical influences like soil-acidity and brightness of Sun light. Brighter, the days, brighter the colour of autumn leaves and vice versa.\nLeaves containing primarily anthocyanins will appear red. Leaves with good amounts of both anthocyanins and carotenoids will appear orange. Leaves with carotenoids but little or no anthocyanins will appear yellow. In the absence of these pigments, other plant chemicals also can affect leaf color. An example includes tannins, which are responsible for the brownish color of some Oak leaves. \nHope that clears your doubt.\nbye..

Cellulose is a long chain carbohydrate polymer, with general formula (C6H10O5)n where n is the number of repeating units.\nIt burns completely to CO2 and H2O.\nThe correct ratio of H/O for water is already present, so you need only enough O2 to convert C to CO2, and there are 6n C atoms in the polymer plus 5n water molecules....so\n(C6H10O5)n + 6n O2 ---> 6n CO2 + 5n H2O\nFor all practical purposes, you can leave out all the n's\n\nMake sense?  :-))

The leaves (or whatever is green) on the plant make photosynthesis from sunlight---our sun gives its strongest, most energetic light in green---which is why our plant world is green---- to absorb the sun's green light the best. Water and minerals come up the roots. We breathe oxygen and exhale carbon dioxide, plants breathe cabon dixoide and exhale oxygen. Cool, isn't it?\n\nSome plants in the desert have the abiity to generate new leaves in just a day or two when it rains. Rainwater has nitrogen  \n\nThe overall equation for photosynthesis is deceptively simple. \n\n6CO2 + 6H2O + light energy = C6H12O6 + 6O2\n\nThe product of photosynthesis is a carbohydrate, such as the sugar glucose, and oxygen which is released to the atmosphere. All of the sugar produced in the photosynthetic cells of plants and other organisms is derived from the initial chemical combining of carbon dioxide and water with sunlight. This chemical reaction is catalyzed by chlorophyll acting in concert with other pigment, lipid, sugars, protein, and nucleic acid molecules. Sugars created in photosynthesis can be later converted by the plant to starch for storage, or it can be combined with other sugar molecules to form specialized carbohydrates such as cellulose, or it can be combined with other nutrients such as nitrogen, phosphorus, and sulfur, to build complex molecules such as proteins and nucleic acids.
