Cellular respiration always begins with glycolysis, which can occur either in the absence or presence of oxygen. Cellular respiration that proceeds in the absence of oxygen is anaerobic respiration. Cellular respiration that proceeds in the presence of oxygen is aerobic respiration.May 6, 2020
Explanation:
What happens when there is no oxygen available?
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.
What would happen to cellular respiration in the absence of oxygen?
In aerobic respiration, one molecule of glucose is broken down to produce 34 to 36 molecules of ATP, the energy currency of the cell. If there was no oxygen available, aerobic respiration would stop and organsims that rely on aerobic respiration would die.Nov 28, 2016
In anaerobic respiration, glucose breaks down without oxygen. The chemical reaction transfers energy from glucose to the cell. Anaerobic respiration produces lactic acid, rather than carbon dioxide and water. Unfortunately this can lead to painful muscle cramps.
