Glycolysis

What is the main product of glycolysis?

Pyruvate, produced from glucose.

What is the role of ATP in glycolysis?

ATP is consumed in the preparation phase and produced in the payoff phase, resulting in a net gain of 2 ATP.

Which enzyme is primarily responsible for the regulation of glycolysis?

Phosphofructokinase (PFK) is a key regulatory enzyme.

What is the end product of glycolysis under anaerobic conditions?

Lactate is produced from pyruvate during lactic acid fermentation.

What are the two types of high-energy molecules produced during glycolysis?

ATP and NADH.

Explain the significance of the preparation phase in glycolysis.

It traps glucose and prepares it for further breakdown into energy.

What happens to pyruvate in aerobic conditions?

It is converted into acetyl-CoA for entry into the Krebs cycle.

What are the consequences of lactate accumulation in muscles?

Can lead to muscle fatigue and soreness due to temporary anaerobic conditions.
