LIFE SCIENCE

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: -Carbohydrates are the body’s main source of quick energy because very little energy is required to break them down. There are three classes of carbohydrates: monosaccharides, disaccharides, and polysaccharides.

Detailed explanation-3: -Likewise, carbohydrates, which are made up primarily of molecules containing atoms of carbon, hydrogen, and oxygen, are essential energy sources and structural components of all life, and they are among the most abundant biomolecules on Earth.

Detailed explanation-4: -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-5: -Explanation: There are four classes of biological molecules: fats, carbohydrates, proteins, and nucleic acids. Of these, fats produce the most energy per gram at a whopping nine calories per gram. Carbohydrates and proteins produce less than half of this, at only four calories per gram.
