The correct statement regarding glycolysis is e) oxygen is not required.
Glycolysis is the metabolic pathway that converts glucose into pyruvate while generating small amounts of ATP and NADH. It occurs in the cytoplasm of the cell and does not require oxygen, making it an anaerobic process. This means that whether or not oxygen is present, glycolysis can still proceed. The other statements are false because:
- a) ATP is not formed: This is incorrect because glycolysis produces a net gain of 2 ATP molecules.
- b) NADH is not formed: This is false; glycolysis produces 2 molecules of NADH.
- c) Glucose is not catabolized: This statement is also false since glycolysis involves the breakdown of glucose.
- d) Pyruvate is not formed: This is incorrect as the end product of glycolysis is pyruvate.
Thus, the only true statement regarding glycolysis is that it does not require oxygen.
