Answer 1

Answer:

1. Lactic fermentation is a minor process which occurs after glycolysis in anaerobic respiration. In it, an enzyme found in most every organism called lactate dehydrogenase catalyzes a reaction between the NADH produced from glycolysis with the pyruvate molecules to create the NAD+ necessary to begin glycolysis.

2. 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

3. ATP

4.The electron transport chain is the third and final step of cellular respiration. ... Toward the end of the electron transport chain, the hydrogen from the coenzymes meets the oxygen that the cell has consumed and reacts with it to form water. In this way, water is created as a byproduct of the metabolism reaction.

5. The yeast simply switches from aerobic respiration (requiring oxygen) to anaerobic respiration (not requiring oxygen) and converts its food without oxygen in a process known as fermentation.
