Glycolysis is the first step in cellular respiration and is a complex process. Which of the following is NOT true about glycolysis?

• Glycolysis begins with a single glucose molecule and produces two pyruvate molecules

• Glycolysis is an anaerobic process

• Glycolysis is a ten step process

• Glycolysis is energy independent and does not require any energy to take place.

Answer explanation

Glycolysis does require energy in the form of 2 ATP in the first process. The second half does not require energy.
