HUMAN NUTRITION

Detailed explanation-1: -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-2: -Glucose, or blood sugar, is the main source of energy for your body’s cells, tissues, and organs. Glucose can be used immediately or stored in the liver and muscles for later use.

Detailed explanation-3: -Organisms mainly use two types of molecules for chemical energy: glucose and ATP. Both molecules are used as fuels throughout the living world. Both molecules are also key players in the process of photosynthesis.

Detailed explanation-4: -Carbohydrates play a significant role in the body for regular metabolic functions, and along with fat they are our bodies main energy source. However, carbohydrates yield more energy per unit of oxygen than fats. Since anaerobic exercise is in the absence of oxygen, the body uses carbohydrates immediately.
