LIFE SCIENCE

Detailed explanation-1: -The body is a complex organism, and as such, it takes energy to maintain proper functioning. Adenosine triphosphate (ATP) is the source of energy for use and storage at the cellular level.

Detailed explanation-2: -During glycolysis, a glucose molecule with six carbon atoms is converted into two molecules of pyruvate, each of which contains three carbon atoms. For each molecule of glucose, two molecules of ATP are hydrolyzed to provide energy to drive the early steps, but four molecules of ATP are produced in the later steps.

Detailed explanation-3: -It is the creation of ATP from ADP using energy from sunlight, and occurs during photosynthesis. ATP is also formed from the process of cellular respiration in the mitochondria of a cell. This can be through aerobic respiration, which requires oxygen, or anaerobic respiration, which does not.

Detailed explanation-4: -It is beneficial for the cell to break down glucose and store energy in ATP molecules because ATP provides an easily accessible and immediate source of energy for the cell, whereas glucose takes longer to break down and release energy.
