Question

Which of the following elements would be found in the LOWEST amounts in both the cell wall and cell membrane?
2 points
Carbon-C
Phosphorus-P
Hydrogen-H
Sodium-Na

Answer 1

Answer:

carbon

Explanation:

Answer 2

The correct answer will be sodium.

• The cell membrane is mainly composed of phospholipids.

       So the obvious component will be phosphorus and lipid.

        Lipid is a heterogenous compound that is made up of hydrocarbon.

• The cell wall is mainly composed of cellulose. Cellulose is made up of β-d-glucose. The glucose chain is made up of carbon, hydrogen, oxygen.

       So, Sodium would be found in the lowest amounts in both the cell wall  

       and cell membrane.
