The production of energy is:

Explanation

Anaerobic respiration is generally faster than aerobic respiration because it does not require oxygen, allowing cells to produce energy more quickly in the absence of oxygen. This process yields ATP (adenosine triphosphate) through fermentation or other pathways, often resulting in byproducts like lactic acid or ethanol. However, anaerobic respiration produces less ATP per glucose molecule compared to aerobic respiration.
