Question

1. List the steps of Glycolysis. Identify which steps are involved in Energy Investment and which steps are involved in Energy Payoff? Note which steps involve a transfer of Energy?

Answer 1

Glycolysis is the biochemical process in which glucose is broken down into pyruvic acid by a series of interdependent biochemical reactions. In this process, one molecule of glucose is broken down into two molecules of Pyruvic acid. the steps involved in glycolysis are listed here:

The steps in which ATP is utilized constitutes the steps involved in energy investment. e.g Step 1 and step 3.

The steps in which ATP is produced by Substrate level phosphorylation constitutes the steps involved in Energy payoff. e.g. Step 7 and step 10.

The steps in which energy transfer takes place involve the steps leading to the production of NADH and ATP by substrate level phosphorylation.
