EVERYDAY SCIENCE

Detailed explanation-1: -Solution: The energy released during respiration is used for carrying out various life processes. Some of the energy liberated during the breakdown of the glucose molecule is in the form of heat, but a large part of it is converted into chemical energy released by these ATP molecules.

Detailed explanation-2: -Releasing energy Respiration releases energy from food in the form of ATP and heat-it is an exothermic process.

Detailed explanation-3: -The first stage of cellular respiration, called glycolysis, takes place in the cytoplasm. In this step, enzymes split a molecule of glucose into two molecules of pyruvate, which releases energy that is transferred to ATP.

Detailed explanation-4: -So, the correct option is ‘40%’

Detailed explanation-5: -During cellular respiration, glucose is broken down in the presence of oxygen to produce carbon dioxide and water. Energy released during the reaction is captured by the energy-carrying molecule ATP (adenosine triphosphate).
