Question: Which of the following statements describing the process of glycolysis is correct?
The following statement describing the process of glycolysis is correct:
Glycolysis is a ten-step process that converts glucose into two molecules of pyruvate, with the net production of two molecules of ATP and two molecules of NADH.
This statement is correct because it accurately describes the number of steps in glycolysis, the products of glycolysis, and the net production of ATP and NADH.
Other statements about glycolysis that are incorrect include:
- Glycolysis is a two-step process. This is incorrect because glycolysis is a ten-step process.
- Glycolysis produces four molecules of ATP. This is incorrect because glycolysis produces two molecules of ATP.
- Glycolysis requires oxygen. This is incorrect because glycolysis can occur in the absence of oxygen.
Glycolysis is the first step of cellular respiration, and it is a process that all living organisms use to produce energy. Glycolysis occurs in the cytoplasm of the cell, and it does not require oxygen.
The products of glycolysis are two molecules of pyruvate, two molecules of ATP, and two molecules of NADH. The pyruvate can then be further broken down in the Krebs cycle and oxidative phosphorylation to produce more ATP.
Therefore, the correct statement about glycolysis is:
Glycolysis is a ten-step process that converts glucose into two molecules of pyruvate, with the net production of two molecules of ATP and two molecules of NADH.
