NEET BIOLOGY

Detailed explanation-1: -Glucose, a 6-carbon sugar, is a simple carbohydrate or “mono-saccharide.” Sugar is a source of quick energy for the body because it is easily metabolized (broken down).

Detailed explanation-2: -Answer and Explanation: ATP is an organic compound that is the main source of energy for all living systems. Certain researchers prefer to call glucose the main source of energy, but glucose is catabolized into energy. Basically, there are four sources of energy: carbohydrates, lipids, proteins and nucleic acids.

Detailed explanation-3: -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-4: -Lipids are energy-rich organic compounds made of carbon, hydrogen, and oxygen. Lipids contain more energy than carbohydrates. Cells store energy in lipids for later use. Proteins are large organic molecules made of carbon, hydrogen, oxygen, nitrogen, and, in some cases, sulfur.

Detailed explanation-5: -Simple carbohydrates: Various forms of sugar, such as fructose (fruit sugar) and sucrose (table sugar), are simple carbohydrates. They are small molecules, so they can be broken down and absorbed by the body quickly and are the quickest source of energy.
