glycolysis

Question 1

What molecule from food is the primary reactant for glycolysis?

Answer 1

glucose

Question 2

What is a product of glycolysis?

Answer 2

2 pyruvate molecules (3 carbons on each)

Question 3

Does glycolysis require an input of energy?

Answer 3

Yes, two ATP molecules to convert a glucose molecule to two PGAL molecules.

Question 4

Why does the PGAL molecule have higher PE than the glucose molecule.

Answer 4

The energy from the ATP molecule converting to ADP has increased the potential energy of the PGAL.

Question 5

Does pyruvate have more or less potential energy than glucose?

Answer 5

less, four ATP molecules are made as PGAL is converted to pyruvate

Question 6

What is the net production of ATP by glycolysis?

Answer 6

Two ATP are needed, four are produced, so the net production of ATP is two.

Question 7

What molecule acts as an electron acceptor in glycolysis?

Answer 7

NADH accepts electrons when PGAL converts to 1,3 BPG.
