2. Respiration in muscles during heavy exercise.
3. Breakdown of food with the use of oxygen.
4. Production of water at the end of respiration.
5. Respiration seen in yeast.
Answers
Answer:
[a] anaerobic exercise ends, the lactic acid is sent to the liver and converted back into pyruvate which can then be used in aerobic respiration. ... Glycolysis is the first stage of many in cellular respiration, and usually occurs in the presence of oxygen.
[b]Anaerobic respiration happens in muscles during hard exercise. Glucose is not completely broken down, so less energy is released than during aerobic respiration. There is a build-up of lactic acid in the muscles during vigorous exercise. The lactic acid needs to be oxidised to carbon dioxide and water later
.[c]
In the cell, the food (glucose) is broken down into carbon dioxide and water using oxygen. When breakdown of glucose occurs with the use of oxygen it is called aerobic respiration. Food can also be broken down, without using oxygen. This is called anaerobic respiration.
