3 stages of respiration
1)glycolysis (in cytoplasm)
2) citric acid cycle (in mitochondria)
3) ETC and ATP synthase (mitochondria)
Citric acid cycle
pyruvate enters mitochondrion, where it loses one CO2 and is converted to the acetyl group (2-carbon)
proton gradient from ETC powers...
ATP synthase, which is the enzyme that catalyzes the condensation of ADP and an inorganic phosphate to make ATP
Measuring rate of respiration
1) heat production (some energy given off during respiration is liberated as heat)
2) liberation of Carbon dioxide
3) oxygen consumption
