Question

During glycolysis, glucose molecules are broken down to ultimately yield CO2 and H2O. a) True b) False

The cleavage of fructose 1,6-bisphosphate yields two molecules of glyceraldehyde 3-phosphate.

a) True b) False

-------

When subjected to anaerobic conditions, glycolysis in mammalian cells continues and causes a buildup of pyruvate in the cytosol.

a) True b) False

-------

The proteins of the electron transport chain remove a pair of electrons from the reductant molecules NADH + H+ and FADH2, after which the electrons move across the inner mitochondrial membrane to maintain the voltage gradient.

a) True b) False

-------

Gluconeogenesis is a linear reaction pathway the cell employs to generate glucose from pyruvate and uses the same enzymes in what is exactly the reverse of glycolysis.

a) True b) False

Explanation / Answer

1. True

In glycolysis, breakdown of glucose starts, and it is broken into two pyruvate molecules which will further broken down, to ultimately yield energy, CO2 and H2O.

2. False

Cleavage of fructose 1,6-bisphosphate yields two molecules, one is of glyceraldehyde-3-phosphate and other is of dihydroxyacetone phosphate.

3. False

When subjected to anaerobic conditions, glycolysis in mammalian cells continues and cause a buildup of lactate in the cytosol. In anaerobic respiration pyruvate is converted into lactate.

4. True

Electron movement is used to maintain the electrochemical gradient by transferring the hydogen ions into the intermembrane space.

5. True

Glycolysis and gluconeogenesis are exactly reverse of each other and same enzymes are used in reverse order.
