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.

Trees are phototrophs, they produce their own food by using carbon dioxide, water, and sunlight.

Life proceeds on chemistry.  Consumption of carbon proteins (or photosynthesis in plants) leading to the production of ATP (adenosine triphosphate).  ATP, being the energy storage and transfer molecule in just about all living cells is truly the stuff of life.

the equations of cellular respiration and photosynthesis are related because they are the converses of each other. cellular respiration is oxygen and glucose equaling carbon dioxide, water and energy. photosynthesis is when energy, water, and carbon dioxide equal oxygen and glucose. photosynthesis needs cellular respiration and cellular respiration needs photosynthesis.

The citric acid cycle (also known as the tricarboxylic acid cycle, the TCA cycle, or the Krebs cycle) is a series of chemical reactions of central importance in all living cells that utilize oxygen as part of cellular respiration. In aerobic organisms, the citric acid cycle is part of a metabolic pathway involved in the chemical conversion of carbohydrates, fats and proteins into carbon dioxide and water to generate a form of usable energy. It is the second of three metabolic pathways that are involved in fuel molecule catabolism and ATP production, the other two being glycolysis and oxidative phosphorylation.

The process of photosynthesis consists of two sets of chemical reactions called the light reaction and the dark reaction. The light reaction takes place in the grana.  The dark reaction takes place in the stroma.\n\nIn the light reaction, electrons in chlorophyll molecules are excited. In other words the energy photons is used to activate electrons. The energy in excited electrons is used to split water molecules: this is photolysis. Oxygen is produced as a waste product and hydrogen is used to reduce NADP+   to form NADPH. The process involves non-cyclic electron transfer producing both NADPH and ATP and cyclic electron transfer producing just ATP.\n\nThe dark reaction requires energy from both NADPH and ATP. In this part of photosynthesis carbon dioxide is fixed. Energy from NADPH and ATP is used to convert glucose (a six carbon molecule) into ribulose diphosphate (a five carbon sugar molecule). Ribulose diphosphate can combine with carbon dioxide eventually forming glucose

cellular respiration occurs in the presence of oxygen.\nit involves glycolysis and then the krebs cycle and then the electron transport chain.\nte end product of the whole process is the synthesis of ATP which is the energy used in most cellular work. \n\nthat's as simple and general as i can put it. look it up on the net if you need more info. lotsa websites out there.

7 - B.  The typical diamater of a cell is 10 micrometers.\n\n8 - A.  An enzyme is a catalyst, which means it lowers the activation energy of the reaction, causing it to proceed faster.  The enzyme may react briefly with the reactants, but is not consumed in the reaction (i.e. there's the same amount of enzyme at the end as there was before the reaction started).\n\n9 - C. Plants use energy from the sun and carbon from carbon dioxide to make glucose.  They also need water to supply electrons in an early stage of photosynthesis.\n\n10 - B.  I'm not sure "by-product" is quite the right word as it is the desired product, but ATP is the only one of those four compounds during any stage of celluar respiration.  Starch can be broken down into glucose, and glucose is the sugar that is burned during cellular respiration.  Chlorophyll is found in plants and is involved in photosynthesis, but has no role in cellular respiration.

Carbon dioxide is food for plants, more CO2, more assimilation.

Cell Respiration is the process by which the chemical energy of "food" molecules is released and partially captured in the form of ATP. Carbohydrates, fats, and proteins can all be used as fuels in cellular respiration, but glucose is most commonly used as an example to examine the reactions and pathways involved.

Cells produce water and carbon dioxide as by-products of metabolic breakdown of sugars, fats, and proteins. Chemical groups such as nitrogen, sulfur, and phosphorous must be stripped, from the large molecules to which they were formerly attached, as part of preparing them for energy conversion. The continuous production of metabolic wastes establishes a steep concentration gradient across the plasma membrane, causing wastes to diffuse out of cells and into the extracellular fluid.\n\nSingle-celled organisms have most of their wastes diffuse out into the outside environment. Multicellular organisms, and animals in particular, must have a specialized organ system to concentrate and remove wastes from the interstitial fluid into the blood capillaries and eventually deposit that material at a collection point for removal entirely from the body.

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.

NADH is produced in organisms in glycolysis and the Krebs cycle (TCA) cycle.  Formation of NAD+ to NADH is reduction.  NADH is produced to create reduction power for the cell.  Some of the reduction power is used in cellular synthesis reactions, but most of the reducing power is brought to the electron transport chain where it is manipulated to create alot of energy in the form of ATP.  Most of the energy created in eukaryotic cells (human, plant, algal, and fungal cells) is created using hte reduction power from NADH to create ATP at the mitochondria.
