Question

Framework elements take part in

• A. Synthesis of protoplasm
• B. Synthesis of cell wall
• C. Formation of storage products
• D. Both B and C

Answer 1

The correct option is D Both B and C

The elements like carbon, hydrogen, and oxygen are known as framework elements as these are basic elements which provide the structural framework to cell and also forms an integral part of the storage products. Oxygen is the most abundant element for the living organism. It is used for respiration. The oxygen inhaled supports the oxidation of food and releases energy. It plays an important role in the oxidative phosphorylation occurring in the mitochondria. The process produces energy in form of ATP. Carbon and hydrogen is an important constituent of carbohydrates which is an instant source of energy. Cellulose which is an important constituent of the cell wall is made up of carbon, hydrogen, and oxygen. Glycogen is the storage product made up of carbon, hydrogen, and oxygen.

So, the correct answer is option D.
