Question

1. during glycolysis, a molecule of glucose is broken down into two molecules of ____________. 9. there are __ atp molecules produced with a net result of ____ atp’s in glycolysis.

Explanation:

Question 8

Glycolysis is a metabolic pathway in biology (subfield of Natural Science) where glucose is broken down. The end product of glycolysis for one glucose molecule is two molecules of pyruvate (or pyruvic acid).

Step1: Recall Glycolysis ATP Production

In glycolysis, the energy investment phase uses 2 ATP molecules (to phosphorylate glucose and then fructose - 6 - phosphate). The energy payoff phase produces 4 ATP molecules (through substrate - level phosphorylation of 1,3 - bisphosphoglycerate and phosphoenolpyruvate).

Step2: Calculate Net ATP

To find the net ATP, we subtract the ATP used from the ATP produced. So, total ATP produced is 4, and net ATP is \(4 - 2=2\).

Answer:

pyruvate (or pyruvic acid)
