Q: What is the role of glucose in cellular respiration?
Answer:
Pyruvate? Acetyl CoA? NADH? FADH2? oxygen? carbon dioxide? water? Glucose:
convert into ATP which the cell then uses to carry out processes and grow Pyruvate:
product of glycolysis (2); initial storage for glucose; most energy into pyruvate
Acetyl CoA: stores energy from pyruvate; product of transport reactions NADH
AND FADH2: energy carriers Oxygen: last electron recepter Carbon dioxide: waste
released into the mitochondria Water: waste
Q: In which process(es) of cellular respiration is ATP synthesized?
Answer:
glycolysis, citric cycle, and electron transport chain
Q: How many carbon dioxides are released from the cellular respiration of 1
glucose molecule?
