Respiration

Question 1

Stages in respiration:

Answer 1

• glycolysis: glucose is oxidised to pyruvate in the cytoplasm. Small amount of ATP is produced.
• during the link reaction pyruvate is converted into acetyl coenzyme A. This reaction connects glycolysis in the cytoplasm and the krebs cycle in the mitochondria.
• The krebs cycle is a series of oxidation reduction reactions that generate NADH and a small amount of ATP
• during oxidative phosphorylation, reduced coenzyme such as NADH, are used to regenerate lots of ATP through the electron transport chain. Oxygen is converted into water.
