Question

1. Production of lactic acid at the end of respiration. ​

Answer 1

Answer:

Lactate reacts with oxidized nicotinamide adenine dinucleotide (NAD+) to form pyruvate, reduced nicotinamide adenine dinucleotide (NADH), and a proton (H+). ... Water, because at the end of the mitochondrion electron transport chain — part of ATP synthesis through oxidative phosphorylation (a.k.a.

Answer 2

Answer:

hope it helps

Explanation:

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.

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.
