Respiration 3. Chemistry of aerobic respiration
2
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
3
Aerobic Respiration Aerobic Respiration involves the presence of oxygen and it occurs in 2 stages:- 1- Glycolysis 2- Breakdown of Pyruvate C 6 H 12 0 6 + 60 2
4
Glycolysis Glycolysis is the splitting of glucose into 2 molecules of pyruvate Glycolysis produces 2 ATP This happens in the Cytoplasm Pyruvate
5
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
6
Energy released during respiration Living seedsDead seeds
7
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?
8
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?
