Large quantities of oxygen are dissolved in water and make up a large percentage of air. Organisms extract it from these media. The ultimate source of molecular oxygen in the air and water appears to be as a byproduct of photosynthesis in plants and some single-celled organisms.
Anaerobic respiration does not require oxygen, while cellular respiration does. Anaerobic respiration produces less energy compared to cellular respiration.
cellular respiration
The reactants in cellular respiration are glucose and oxygen. Glucose is broken down in a series of reactions to produce energy, carbon dioxide, and water, with oxygen acting as the final electron acceptor in the process.
O2 ADDED: Not O2, but one atom of oxygen.
Cellular respiration is the process by which cells break down glucose to produce energy in the form of ATP. Aerobic respiration specifically refers to the type of cellular respiration that requires oxygen to produce ATP. In contrast, anaerobic respiration does not require oxygen.
Mitochondrion
Glucose and oxygen enter a cell's cytoplasm for aerobic cellular respiration.
Oxygen is the difference! Cellular respiration requires oxygen, while cellular fermentation does not.
Yes, Oxygen is required for cellular respiration.
Cellular respiration need oxygen. This oxygen is supplied by external respiration
If by respiration you mean breathing, the substance coming in is oxygen.
Cellular respiration uses oxygen.
Because cellular respiration occurs in the presence of oxygen.
cellular respiration uses oxygen but fermentation does not use oxygen

Anaerobic respiration does not require oxygen, while cellular respiration does. Anaerobic respiration produces less energy compared to cellular respiration.
cellular respiration requires oxygen while fermentation does not
