Question

Is 02 converted into CO2 during cellular respiration? Explain. What is the purpose of fermentation? What are the two things we obtain by eating food? What are they used for?

Answer 1

Answer =

No = O2 is not converted into CO2 during cellular respiration

Explanation = cellular respiration is the intracellular process of oxidation in which organic substances are breakdown in step wise manner with the release of energy which is immediately converted into ATP.

The equation for cellular respiration is as follows:

C6H12O6 + 6O2 $\rightarrow$ 6CO2 + 6H2O +ATP

During cellular respiration , glucose is broken down into in the presence of oxygen to produce carbon dioxide and water.

=======================================================================================

Loss of hydrogen atoms (oxidation) + 66 - 6 + 6 CH,206 0 COHO Carbon Water Glucose Oxygen Energy stored in ATP Gain of hydrogen atoms (reduction CO2 comes from glucose it does not comes from Oxygen. Oxygen is converted water.

The purpose of fermentation is

fermentation is defined as a chemical change brought about in an organic substrate due to the activity of microorganisms or enzymes produced by microorganisms.

The main important purpose is to regenerate the electron carriers used in glycolysis & produce a small amount of ATP.

fermentation is an important process for anaerobic organisms to produce energy.
