Answer 3

glycolysis

Question 4

Which of the following sequences represents the correct order in which metabolic reactions occur during the complete oxidation of glucose through aerobic respiration?

Answer 8

substrate-level phosphorylation

Question 9

Which of the following statements describes a primary function of both alcohol fermentation and lactic acid fermentation?

Answer 9

to oxidize NADH to NAD+

Question 10

Which statement below best describes the results of the complete reactions of cellular respiration in the presence of oxygen (C6H12O6 + 6 O2 → 6 CO2 + 6 H2O + energy)?

Answer 10

C6H12O6 is oxidized and O2 is reduced
