The body needs oxygen because without it, cells cannot function. The respiratory system brings in oxygen to the body, and it is circulated throughout the body via the blood in the circulatory system. The oxygen is a key ingredient in many cell processes, and without it, the body would fail.
Oxygen is required for many processes in the body including making energy.
Respiration occurs in two phases: anaerobic, which does not require oxygen, and aerobic which does require oxygen.
Most animals, including humans, require oxygen for respiration. This includes mammals, birds, reptiles, and many invertebrates. Additionally, some bacteria and fungi also require oxygen for their respiration processes.
Glycolysis is the only part of cellular respiration that does not require oxygen. It is the process by which glucose is broken down to produce pyruvate and a small amount of ATP. The subsequent steps of cellular respiration, including the Krebs cycle and electron transport chain, require oxygen to fully extract energy from glucose.
This is anaerobic respiration, also called fermentation or substrate level phosphorylation
In organisms that undergo anaerobic respiration, glycolysis occurs, which does not require oxygen. After glycolysis, fermentation takes place to regenerate NAD+ for glycolysis to continue in the absence of oxygen. The citric acid cycle and oxidative phosphorylation, which require oxygen, do not occur in anaerobic respiration.
Respiration occurs in two phases: anaerobic, which does not require oxygen, and aerobic which does require oxygen.

Aerobic respiration requires oxygen and Anaerobic respiration does not require oxygen!

Oxygen is essential for aerobic respiration, oxygen helps blood flow which helps with our circulation. Anaerobic respiration does not require oxygen.

respiration
The major difference between anaerobic respiration and aerobic respiration is the presence of oxygen. Anaerobic respiration does not require oxygen and produces less energy, while aerobic respiration requires oxygen and produces more energy. Anaerobic respiration typically produces lactic acid or ethanol as byproducts, while aerobic respiration produces carbon dioxide and water.
yes they do
Aerobic respiration is the respiration that requires oxygen. It needs oxygen in order to generate ATP. Anaerobic respiration does not require oxygen.
