only during the day

when there is less oxygen available

Detailed explanation-1: -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.
Detailed explanation-2: -During strenuous exercise when oxygen is less it causes lactic acid buildup leading to muscle fatigue. Inadequate oxygen drives muscles towards anaerobic respiration.
Detailed explanation-3: -In animals Most organisms cannot respire without oxygen. But some organisms and tissues can continue to respire if the oxygen runs out. These organisms and tissues use the process of anaerobic respiration.
Detailed explanation-4: -Glycolysis, which is the first step in all types of cellular respiration is anaerobic and does not require oxygen. If oxygen is present, the pathway will continue on to the Krebs cycle and oxidative phosphorylation. However, if oxygen is not present, some organisms can undergo fermentation to continually produce ATP.
Detailed explanation-5: -Anaerobic respiration is also referred to as fermentation. When in absence of oxygen, the glucose molecule is broken down to produce alcohol and energy it is referred to as anaerobic respiration. It is majorly observed in lower groups of animals and fungi. It happens in the cytoplasm of the cell.
