Question

In our bodies, glycolysis is able to take place in both the presence and the absence of oxygen. When oxygen is present, pyruvate is the end product of glycolysis. What is the end product of glycolysis when oxygen is not present?

Lactate

Glucose

ADP

ATP

Answer 1

Option A: Lactate

Step-by-step explanation:

In the absence of oxygen, anaerobic respiration takes place and pyruvate is converted to lactate to regenerate NAD+ for glycolysis to produce energy as the oxidative phosphorylation is unable to occur in the absence of oxygen

Answer 2

Lactate

Step-by-step explanation:

Glycolsis without oxygen is called anaerobic respiration which is the breakdown of glucose in the absence of oxygen resulting in lactic acid, carbon dioxide, and water as end products
