Question

question 4 (1 point)
what is required for aerobic cellular respiration to occur?
glucose, oxygen, and adp
carbon dioxide, atp, and water
glucose, atp, and water
oxygen, water, and glucose
question 5 (1 point)
in which order do the stages of aerobic cellular respiration occur?
glycolysis, krebs cycle, pyruvate oxidation, electron transport chain.
krebs cycle, glycolysis, electron transport chain, pyruvate oxidation.
glycolysis, pyruvate oxidation, krebs cycle, electron transport chain.
glycolysis, krebs cycle, electron transport chain, pyruvate oxidation.
question 6 (1 point)
which of the following occurs during glycolysis?
the formation of four atp molecules
the addition of two phosphates to glucose
the formation of two molecules of pyruvate
all of the above.

Explanation:

• Question 4: Aerobic cellular respiration uses glucose as the fuel source, oxygen as the final electron - acceptor, and ADP is required to produce ATP. Carbon dioxide and water are products, not reactants.
• Question 5: The correct order of stages in aerobic cellular respiration is glycolysis (which breaks down glucose to pyruvate), pyruvate oxidation (converts pyruvate to acetyl - CoA), Krebs cycle (oxidizes acetyl - CoA), and electron transport chain (generates most of the ATP).
• Question 6: During glycolysis, two phosphates are added to glucose, four ATP molecules are formed (net gain of 2 ATP), and two molecules of pyruvate are produced.

Answer:

• Question 4: glucose, oxygen, and ADP
• Question 5: glycolysis, pyruvate oxidation, Krebs cycle, electron transport chain.
• Question 6: all of the above.
