what happens to the carbon dioxide produced in breaking down pyruvic acid?

In the human body, the CO2 diffuses out of the mitochondria into the cytoplasm.  From the cytoplasm, it diffuses through the plasma membrane into the interstitial fluid, and into the bloodstream.  The circulatory system takes the CO2 to the lungs where it is diffused into the alveoli and is exhaled into the environment.  \n\nIn bacteria and yeast, the waste product of CO2 is simply excreted into the environment.  The CO2 getting trapped in the gluten is what makes bread rise and gives it's porous texture.  In a liquid, the CO2 is dissolved and it's what gives beer and champagne it's effervescence.

Actually, that is a somewhat simplified reaction,\nin reality, the water and Carbon Dioxide dont form directly, they form after a secondary reaction (Carbonic acid decomposing).\n\n3Na2CO3 + 2H3PO4 --> 2Na3PO4 + 3H2CO3\nH2CO3 --> H2O + CO2\n\nSo combining them,\n3Na2CO3 + 2H3PO4 --> 2Na3PO4 + 3H2O + 3CO2

YES that is true . when we take in the food  during the process of respiration the glucose is broken down to pyruvic acid CH3COC0OH BY THE process of glycolysis , initially by taking oxygen by cytoplasm . when it gets more oxygen the pyruvic acid enters mitochondria and is converted to CO2 AND H20 . This cycle is called KREB's cyle . the synthesis of ATP molecule takes place in the F1 particle of mitochondria . \nthe equaton is \nC6H12O6+O2---->CH3C0COOH + O2--->CO2 + H20 \nthis process is called aerobic trespiration \nrespiration invoves oxidation of food ....\nPLEASE VOTE IT AS THE BEST ANSWER IF YOU LIKE IT ..PLEASE......\nI THINK I HAVE ANSWERED YOUR MANY QUERIES

In Photosynthesis, plants use the sun's energy as light to transform carbon dioxide and water into glucose.  In cellular respiration,  glucose is ultimately broken down to yield carbon dioxide and water, and the energy from this process is stored as ATP molecules.

==================================\nNAD+ is probably your answer.\n\nThe products of alcohol fermentation are:\nAlcohol (Ethanol) ATP, carbon dioxide \n\nSo you know for certain that your answer is either Pyruvic Acid or NAD+\n=======================\nI would argue that your teacher wants you to say NAD+ is NOT the by-product because NAD+ is converted to NADH.  Here's another way of looking at it:\n\nAlcohol fermentation is the formation of alcohol from sugar. Yeast, when under anaerobic conditions, convert glucose to pyruvic acid via the glycolysis pathways, then go one step farther, converting pyruvic acid into ethanol (alcohol).\n==============================

changes oxygen into carbon dioxide, the carbon come from the burning fuel

Baking soda is sodium bicarbonate (NaHCO3), and Vinegar contains acetic acid (HC2H3O2).  When these two reactants are mixed it produces carbonic acid (H2CO3) which is very unstable and the carbonic acid immediately breaks down into Carbon dioxide (CO2) and water.  The "fizz" you see is the CO2 gas escaping from the water.\n\nNaHCO3 + HC2H3O2 --> H2CO3 ---> CO2 + H2O

1: will release carbon dioxide gas from carbonates\n\n2: will produce hydrogen when reacted with metals such as iron, zinc etc.

ATP, NADH, FADH2, AND CO2\nGlycolsis start with glucose synthesis and goes through the Krebb Cycle with beginning of oxidation of Pyruvate,the end result is in the Transport Chain system with C02.

Remember, mitochodria are the locale for oxidative respiration.  Glucose and fatty acids are broken down to pyruvate during glycolysis, which occurs in the cell cytoplasm and does not require oxygen. The pyruvate molecules are transported into the mitochodria where they're utlized to produce energy (ATP) via the Kreb's cycle (which occurs in the mitochodria).  This process requires oxygen, thus the term "oxidative respiration".  Lack of oxygen results in loss of ATP production, and utlimately cell death.

The pink is an indication of slightly basic.  However, the CO2 in the air will dissolve in water and form carbonic acid.  The acid will neutralize the OH-, and the color fades.

glycolysis is the process by which the glucose made in photosynthesis is broken down.\n\nIt takes place in the cells cytoplasm.\n\nUses glucose(sugar) and oxygen\n\nMakes carbon dioxide and water

You can have anaerobic respiration and aerobic respiration. The ultimate result is ATP. Anaerobic is done without oxygen (fermentation) and aerobic is done with oxygen,\n\nit starts with glycolosis which takes place in the cytoplasm. Glucose is turned into two pyruvates through a 10 reaction process meditated my enzymes. you produce one ATP and one NADH\n\nthen the pyruvates go into Krebs Cycle or the TriCarboxylic Acid Cycle and goes into the mitochondria. The pyruvate must be converted to acetyl Coenzyme A. then the acetyl Co A enters Krebs and continuously generates Oxaloacetate among other enery-rich compounds such as ATP, NADH and FADH2 with CO2\n\nthen final process is in the electron transport chain which takes place in the inner membrane if the mitochondria. In this process lots of H+ is pumped out of the membrane, which means that H+ is accumalated outside the inner matrix. then the concentration gradient causes a sudden influx of H+ back into the inner membrane which creates "proton-motive force" which zaps ADP+Pi= ATP. \n\nthe end result is 38 ATP for regular cells or 36 ATP for muscles and brain cells.\n\nOXYGEN IS REQUIRED!!! \n\nhope that helps\n\n*oh and ATP is a form of energy for the cell...

Recycling and pollution control. The fuel production company generates CO2, which it then feeds to plants. The plants absorb CO2, reducing the  company's CO2 emissions. In addition, the plants convert the CO2 into cellulose, which can be burned as fuel.

Aerobic respiration is a more complete decomposition. It breaks sugars down into water and CO2. Anerobic respiration breaks things down into CO2, and Alcohol. (Alcohol can still be burned for more energy, whereas CO2/H20 can't)

aerobic respiration works by breaking down glucose into carbon dioxide and water molecules.  This provides the cell a chemical form of energy called ATP which is used for all cellular functions.  The way it works is by a series of chemical reactions that creates ATP molecules by breaking bonds in the glucose.  It is often called a step wise reaction because it take several steps.  The reason for this is so all the engery is not realeased at onces creating a lot of heat.  (For example burning sugar realeases all the enrgey quickly, but creates a lot of wasted heat)  First the gluclose is broken down into pyruciv acid in the cytoplasam, which creates 2 ATP, then in the mitochondria it is broken down further sending molecueles with Hydrogen atoms to the Electron Transport Chain where oxygen is needed.  This is why it is call aerobic respiration.  This is  the main ATP (energy) producing step.  Overall for each glucose molecule you get a net gain of about 32 ATPs I believe.  \n\nIf you want more details, just look it up in a biology book.  I am sure there are great diagrams you could look at to help see the process.

the vinegar is a solution of water and acetic acid.  the acetic acid exists as acetate ion and hydrogen ion.  the bicarbonate is a sodium ion and a bicarbonate ion.  when the two combine, the postive hydrogen ion combines with the negative bicarbonate ion to produce carbon dioxide and water, and the negative acetate ion and the postive sodium ion combine (well, they really don't combine, they stay apart and disolved in the solution) to become sodium acetate.  what's left is a water solution with sodium acetate desolved in it and bubbles of carbon dioxide coming out of the solution.
