EVERYDAY SCIENCE

Detailed explanation-1: -Explanation: Basically it is not used to provide energy. Protein helps to repair and build your body tissues. It is not the energy provider.

Detailed explanation-2: -Protein helps repair and build your body’s tissues. It drives metabolic reactions, maintains pH and fluid balance, and keeps the immune system strong. It also transports and stores nutrients and can act as an energy source. Protein is crucial to good health.

Detailed explanation-3: -Proteins help fight disease, control the rate of reaction and move substances into or out of cells. However, proteins do not store and transmit genetic information and thus the correct answer is A.

Detailed explanation-4: -For any substance to be genetic material, it must be able to replicate. It must be structurally and chemically stable. It must also provide scope for mutation which is a necessary condition for evolution. Proteins can not replicate, although they can cause replication in other entities (prions).

Detailed explanation-5: -Proteins have multiple functions, including: acting as enzymes and hormones, maintaining proper fluid and acid-base balance, providing nutrient transport, making antibodies, enabling wound healing and tissue regeneration, and providing energy when carbohydrate and fat intake is inadequate.
