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.

What limits us from doing cellular respiration?
A lack of oxygen can limit people from cellular respiration. As well as oxygen, food also limits cellular respiration.
What are the reactant in the equation for cellular respiration?
glucose and oxygen are the reactants of cellular respiration
What is the final hydrogen acceptor in cellular respiration of most plants and animals?
For animals, the final hydrogen acceptr in cellular respiration is
The process that releases energy from food in the presence of oxygen is?
Cellular Respiration Biology 1 honors student.
What product of photosynthesis is needed by both plants and other organisms for cellular respiration?
The products of photosynthesis are glucose and oxygen. Oxygen is used in cellular respiration.
Where does oxygen come from in cellular respiration?
Mitochondrion
Where does glucose an oxygen come for to react in cellular respiration?
Glucose and oxygen enter a cell's cytoplasm for aerobic cellular respiration.
What are the difference cellular respiration and respiration?
Oxygen is the difference! Cellular respiration requires oxygen, while cellular fermentation does not.
Why is oxygen necessry for cellular respiration?
Yes, Oxygen is required for cellular respiration.
Why is external respiration vital to cellular respiration?
Cellular respiration need oxygen. This oxygen is supplied by external respiration
In cellular respiration what substances come from the outside?
If by respiration you mean breathing, the substance coming in is oxygen.
What happens if an organism performs cellular respiration without oxygen?
Anaerobic respiration does not involve oxygen.
Cellular respiration involves the use of carbon dioxide or oxygen?
Cellular respiration uses oxygen.
What can cellular respiration be?
Cellular respiration can be anaerobic (without oxygen) or aerobic (occurs in the presence of oxygen).
Why is cellular respiration an aerobic respiration?
Because cellular respiration occurs in the presence of oxygen.
What limits us from doing cellular respiration?
A lack of oxygen can limit people from cellular respiration. As well as oxygen, food also limits cellular respiration.
What are the reactant in the equation for cellular respiration?
glucose and oxygen are the reactants of cellular respiration
