Where does the oxygen in respiration come from?
The oxygen in respiration comes from your lungs. You breathe the oxygen in, it gets in to your blood stream and is delivered to your cells.
glucose and oxygen are the reactants in this equation, glucose come from the sugars broken down from your food and oxygen come from your lungs, passing through the thin cell wall of the bronchioles into your bloodstream which are in turn absorbed by the mitochondria and the process of respiration takes place
Aerobic Respiration is a respiration of a bacteria with oxygen. Glucose + Oxygen --> Energy + Water + Carbon Dioxide Anaerobic Respiration is a respiration of a bacteria without the presence of oxygen. Glucose -- > Energy + Carbon Dioxide -----by vigneshsherlekar Aerobic Respiration is a respiration of a bacteria with oxygen.

respiration without oxygen present is anaerobic respiration. & fermentation occurs when oxygen is not present. fermentation= A+LS If oxygen is not present; anaerobic respiration begins to occur. Anaerobic respiration does not need oxygen. It happens when there is not enough oxygen for aerobic respiration. Here is the word equation: glucose → lactic acid (+ energy) Much less energy is released by anaerobic respiration than by aerobic respiration.
If by respiration you mean cell respiration, then yes oxygen is consumed in the process of cell respiration. As a matter of fact, oxygen is the last electron acceptor in the electron transport chain, the last stage of cell respiration. In cell respiration, you produce ATP, which is essentially used by your body to get energy. That is why you need oxygen! !!
