Respiration 3. Chemistry of aerobic respiration

Respiration Respiration is the process by which chemical energy is released in cells during the breakdown of food e.g. glucose Aerobic Respiration produces 38 ATP Anaerobic Respiration produces 2 ATP

Aerobic Respiration Aerobic Respiration involves the presence of oxygen and it occurs in 2 stages:- 1- Glycolysis 2- Breakdown of Pyruvate C 6 H

Glycolysis Glycolysis is the splitting of glucose into 2 molecules of pyruvate Glycolysis produces 2 ATP This happens in the Cytoplasm Pyruvate

Breakdown of Pyruvate This stage produces 36ATP This stage happens in the Mitochondria Total ATP produced in Aerobic Respiration is 38ATP Carbon Dioxide + Water Pyruvic Acid + Oxygen 36ADP + 36Pi 36ATP Pyruvate + Oxygen

Energy released during respiration Living seedsDead seeds

Experiment conclusions Why were fresh peas and dead peas used in the experiment? Why were the peas disinfected before use? What is excess energy from respiration released as?

Recap Write an exit summary to tell me the following: Describe the processes involved in aerobic respiration: What is glycolysis? What is glucose split in to? How many ATP are produced per glucose molecule?
