Final answer:
Glycolysis is the process of breaking down glucose into pyruvate. It involves oxidation-reduction reactions, can occur in the absence of oxygen, and ATP synthesis occurs by substrate-level phosphorylation.
Step-by-step explanation:
Glycolysis is the process of breaking down glucose into pyruvate. It is the first step in cellular respiration and occurs in the cytoplasm of cells. Now, let's go through the options:
A. Oxidation-reduction reactions occur during glycolysis: This is true. Glycolysis involves both oxidation and reduction reactions.
B. Glycolysis can occur in the absence of oxygen: This is true. Glycolysis is an anaerobic process and does not require oxygen.
C. ATP Synthesis during glycolysis occurs by substrate-level phosphorylation: This is true. ATP synthesis in glycolysis occurs by substrate-level phosphorylation, where ATP is directly synthesized from enzymatic reactions.
D. All of the above are true: This option is not true. The correct answer is D. None of the above are false.
