BIOMOLECULES AND ENZYMES

Detailed explanation-1: -Metabolism or metabolic rate is defined as the series of chemical reactions in a living organism that create and break down energy necessary for life. More simply, it’s the rate at which your body expends energy or burns calories.

Detailed explanation-2: -Metabolism: Converting food into energy. Metabolism is the process by which the body changes food and drink into energy. During this process, calories in food and drinks mix with oxygen to make the energy the body needs.

Detailed explanation-3: -A slow metabolism burns fewer calories, which means more get stored as fat in the body; that’s why some people have difficulty losing weight by just cutting calories. A fast metabolism burns calories at a quicker rate, which explains why some people can eat a lot and not gain extra pounds.

Detailed explanation-4: -When the number of calories you take in from food matches the number of calories you burn to sustain your metabolism, digestion, and physical activity, your weight will remain stable. Thus, the “calories in versus calories out” model is strictly true. You need a calorie deficit to lose weight.
