BIOMOLECULES AND ENZYMES

Detailed explanation-1: –Organisms use carbohydrates produced by photosynthesis by oxidizing them to produce energy for respiration.

Detailed explanation-2: -Carbohydrates are the nutrients most frequently used as an energy source (containing 4kcal per gram), as they are fast-acting and turn into energy as soon as they are ingested. This energy powers the brain and body. The energy that powers the brain and body is generated when carbohydrates are broken down.

Detailed explanation-3: -Glycogen is a complex carbohydrate that the body can easily and rapidly convert to energy. Glycogen is stored in the liver and the muscles. Muscles use glycogen for energy during periods of intense exercise.

Detailed explanation-4: -Carbohydrates closer to exercise are best as they can provide immediate glucose, versus fats which take longer to metabolize.

Detailed explanation-5: -Most of the carbohydrates in the foods you eat are digested and broken down into glucose before entering the bloodstream. Glucose in the blood is taken up into your body’s cells and used to produce a fuel molecule called adenosine triphosphate (ATP) through a series of complex processes known as cellular respiration.
