Photosynthesis, when there isn’t enough glucose

Detailed explanation-1: -During anaerobic respiration, lactic acid is produced. This happens when the demand for energy is more and supply of oxygen is less, mainly during heavy exercise. The lactic acid thus formed is broken down by the supply of oxygen.
Detailed explanation-2: -4: Lactic acid fermentation makes ATP in the absence of oxygen by converting glucose to lactic acid (through a pyruvate intermediate). Making lactic acid from pyruvate oxidizes NADH, regenerating NAD+ so that glycolysis can continue to make more ATP rapidly.
Detailed explanation-3: -How cells extract energy from glucose without oxygen. In yeast, the anaerobic reactions make alcohol, while in your muscles, they make lactic acid.
Detailed explanation-4: -In this process two NADH + H+ are converted to two NAD+. Our muscle cells can undergo this process when they are in oxygen debt. If enough oxygen is not present to undergo aerobic respiration, pyruvate will undergo lactic acid fermentation.
Detailed explanation-5: -Lactic acid is the waste product produced during anaerobic respiration.
