Question

During glycolysis, the molecule glucose is broken down into pyruvate. What type of reaction is this?

Answer 1

Answer:

It is a Catabolic reaction.

Explanation:

In catabolic reactions, energy is released as complex molecules are broken down into smaller ones.  

Answer 2

Explanation:

Glycolysis is a set of anaerobic reactions, ones that does not need oxygen to be performed. It takes glucose and breaks it down into pyruvate. This has the result of creating two ATP, which can release energy.

Overall, this process creates four ATP, but it uses two ATP early in the reaction. This means that there is a net gain of two ATP.

The overall equation for this pathway is:

1 glucose + 2 ATP ⟶ 2 pyruvate + 2 NADH + 4 ATP + 2 H2O
