Detailed explanation-1: -Glucose is the most important source of energy for all living things. The food we eat is broken down into carbohydrates, the most important of which is glucose. Glucose is oxidized to provide energy to the body.
Detailed explanation-2: -In a process driven by light energy, glucose molecules (or other sugars) are constructed from water and carbon dioxide, and oxygen is released as a byproduct. The glucose molecules provide organisms with two crucial resources: energy and fixed-organic-carbon.
Detailed explanation-3: -Adenosine 5’-triphosphate, or ATP, is the most abundant energy carrier molecule in cells.
Detailed explanation-4: -Cellular respiration is the process that occurs in the mitochondria of organisms (animals and plants) to break down sugar in the presence of oxygen to release energy in the form of ATP. This process releases carbon dioxide and water as waste products.
