Explanation: 

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: -The primary source of energy in most of the organisms is carbohydrate as it is the most abundant in most of the organism. The carbohydrate is one of the macromolecules which is readily available for being converted to energy as per the requirement of the body.

Detailed explanation-3: -ATP is the most common short-term energy molecule (the energy is store in the phosphodiester bonds). There are four long term energy storge molecules, which are much larger than ATP. They are lipids, proteins, carbohydrates, and nucleic acids. Among them, lipids are the main energy storing molecule in the body.

Detailed explanation-4: -Carbohydrates, also known as carbs, are vital at every stage of life. They’re the body’s primary source of energy and the brain’s preferred energy source. Carbs are broken down by the body into glucose – a type of sugar. Glucose is used as fuel by your body’s cells, tissues, and organs.
