Question

Compare the relative energy storage of the macromolecules

Answer 1

Answer:

Hope this helps you

Explanation:

Glucose energy is stored as glycogen, with the majority of it in the muscle and liver. The liver uses its glycogen reserve as a way to keep blood-glucose levels within a narrow range between meal times. Some glucose is also used as building blocks of important macromolecules, such as RNA, DNA, and ATP.

Answer 2

Answer:

• There are four major biological macromolecules (biomolecules); carbohydrates, lipids, proteins, and nucleic acids. But for the purpose of energy for the body, only carbohydrates, lipids, and proteins are available. Nucleic acids are for the transmission of genetic information.
• Carbohydrates are polymers of monosaccharides. Chemically, these are polyhydroxy ketones or aldehydes. These are the abundant dietary source of the energy in the body. These form different components, such as cellulose, glycogen, starch, etc. Their relative energy content is 1,760 kJ per 100 grams.
• Lipids are not polymeric molecules. These include fats, waxes, fat-soluble vitamins, phospholipids, triglycerides, fatty acids, and sterols. They are the chief source of energy and play important role in the cellular structure. Their relative energy content is 4,000 kJ per 100 grams.
• Proteins are polymers of amino acids and form polypeptides. They are available in primary, secondary, tertiary, and quaternary classes based on structure. They have many dynamic and structural roles. Their relative energy content is 1,720 kJ per 100 grams.
• The comparison of the relative energy storage of the macromolecules; carbohydrates, lipids, and proteins are 1,760, 4,000, and 1,720 kJ per 100 grams, respectively. The highest energy is stored by lipids followed by carbohydrates and proteins.
