Question

15. Respiration is a three-step process that breaks down glucose and produces ATP. Describe each of the three steps.

Answer 1

Answer:

Cellular respiration uses energy in glucose to make ATP. Aerobic (“oxygen-using”) respiration occurs in three stages: glycolysis, the Krebs cycle, and electron transport.

Explanation:

In glycolysis, glucose is split into two molecules of pyruvate. This results in a net gain of two ATP molecules.
