BIOMOLECULES AND ENZYMES

Detailed explanation-1: -After a meal, fat is put into storage. Between meals, stored fat is slowly released, keeping our cells supplied with fuel. While the brain needs glucose, our liver, muscle, and fat cells prefer to burn fat.

Detailed explanation-2: -Triglycerides, cholesterol and other essential fatty acids-the scientific term for fats the body can’t make on its own-store energy, insulate us and protect our vital organs. They act as messengers, helping proteins do their jobs.

Detailed explanation-3: -White fat is specialized to store energy in the form of triglycerides, an especially efficient method because this class of molecules is highly energetic and stored anhydrously. On fasting, the release of fatty acids and glycerol to provide fuel for the rest of the body occurs via enzymatic hydrolysis called lipolysis.

Detailed explanation-4: -Glucose is the main source of fuel for our cells. When the body doesn’t need to use the glucose for energy, it stores it in the liver and muscles. This stored form of glucose is made up of many connected glucose molecules and is called glycogen.

Detailed explanation-5: -Fat is the body’s most concentrated source of energy, providing more than twice as much potential energy as carbohydrate or protein (9 calories per gram versus 4 calories each per gram). During exercise, stored fat in the body (in the form of triglycerides in adipose or fat tissue) is broken down into fatty acids.
