NEET BIOLOGY

Detailed explanation-1: -Cellular respiration takes place in the cells of all organisms. In the cell, the food (glucose) is broken down into carbon dioxide and water using oxygen. When breakdown of glucose occurs with the use of oxygen it is called aerobic respiration. Food can also be broken down, without using oxygen.

Detailed explanation-2: -Cellular respiration is the process by which organisms use oxygen to break down food molecules to get chemical energy for cell functions. Cellular respiration takes place in the cells of animals, plants, and fungi, and also in algae and other protists.

Detailed explanation-3: -While most aerobic respiration (with oxygen) takes place in the cell’s mitochondria, and anaerobic respiration (without oxygen) takes place within the cell’s cytoplasm.

Detailed explanation-4: -Answer and Explanation: The correct answer C. You can obtain energy from both proteins and fat even though the initial energy expenditure is much. The preferred molecule that cells will use to generate energy is glucose.

Detailed explanation-5: -Cellular respiration takes place in the cytoplasm and mitochondria of each cell of the body. Glycolysis occurs inside the cytoplasm, while the TCA cycle occurs inside the matrix of the mitochondria.
