glucose
how does cellular respiration occur
Glucose must be present in order for cellular respiration to occur. Cellular respiration is the process in which glucose is broken down in to ATP (energy), Carbon Dioxide, and water. Glucose is a reactant in the sense that it must be present for the reaction to occur.
Oxygen is the element that must be present for both steps of cellular respiration to occur. It acts as the final electron acceptor in the electron transport chain, allowing for the production of ATP through oxidative phosphorylation.
The anaerobic reactions of cellular respiration occur in the cytoplasm of the cell.
The anaerobic reactions of cellular respiration occur in the cytoplasm of the cell.
mitochondrion
Cellular respiration occurs in the mitochondria.
Cellular respiration occurs most often in the mitochondria of the cell.
By there being no Oxygen during cellular respiration, then another process called Fermentation would occur which carries on with cellular respiration without oxygen molecules being present during the cycle, but the results of cellular respiration would still be the same.
it occurs in the lung
in the cytoplasm
In order for respiration to occur, three things must be present: oxygen, a source of energy (such as glucose), and a metabolic system capable of breaking down the energy source to release energy for cellular processes.
