Detailed explanation-1: -Adenosine 5’-triphosphate, or ATP, is the most abundant energy carrier molecule in cells. This molecule is made of a nitrogen base (adenine), a ribose sugar, and three phosphate groups.
Detailed explanation-2: -Carbohydrates are organic molecules composed of carbon, hydrogen, and oxygen, usually in a ratio of 1:2:1. Carbohydrates include sugars, starch, cellulose, and glycogen. Carbohydrates are the primary sources of energy for most organisms. The sugar glucose is the main source of energy for cells.
Detailed explanation-3: -A molecule of glucose, which has the chemical formula C6H12O6, carries a packet of chemical energy just the right size for transport and uptake by cells. In your body, glucose is the “deliverable” form of energy, carried in your blood through capillaries to each of your 100 trillion cells.
Detailed explanation-4: -Glucose and other food molecules are broken down by controlled stepwise oxidation to provide chemical energy in the form of ATP and NADH.
