Verified step by step guidance1
Step 1: Understand the concept of cellular respiration. Cellular respiration is the process by which cells convert glucose into energy (ATP). It can occur in the presence or absence of oxygen.
Step 2: Learn the difference between aerobic and anaerobic respiration. Aerobic respiration requires oxygen to produce ATP, while anaerobic respiration does not use oxygen and typically produces less ATP.
Step 3: Recognize that fermentation is a type of anaerobic respiration. It occurs in the absence of oxygen and results in byproducts like lactic acid or ethanol, depending on the organism.
Step 4: Understand that photosynthesis is not a form of cellular respiration. It is the process by which plants and some other organisms convert light energy into chemical energy stored in glucose.
Step 5: Conclude that aerobic respiration is the type of cellular respiration that requires oxygen, as it uses oxygen to break down glucose completely into carbon dioxide and water, producing a high yield of ATP.
