Question

Protoplasm is formed of

• A. $\mathrm{C},\mathrm{H},\mathrm{N},\mathrm{and}\mathrm{O}$ ions
• B. $\mathrm{O}\mathrm{and}\mathrm{N}$ ions
• C. $\mathrm{H}\mathrm{and}\mathrm{C}$ ions
• D. $\mathrm{O}\mathrm{and}\mathrm{P}$ ions

Answer 1

The correct option is A

$\mathrm{C},\mathrm{H},\mathrm{N},\mathrm{and}\mathrm{O}$ ions

The correct option is A.

The explanation for the correct option:

1. The protoplasm is the transparent living material of the cell which comprises the nucleus, and cytoplasm and is covered by the cell membrane.
2. The protoplasm is made up of glycoproteins.
3. The composition of glycoproteins is glucose and proteins.
4. The backbone of carbohydrates and proteins is built with carbon, hydrogen, oxygen, and nitrogen ions.

The explanation for the incorrect option:

Option B:

1. Oxygen and Nitrogen ions are also important in the structure of protoplasm
2. Similarly, Carbon is the most essential ion.

Option C:

1. Carbon and hydrogen ions are not the only components in the protein.
2. Nitrogen and oxygen are also present in glycoproteins.

Option D:

1. Phosphorus is not always present in all the structures of glycoprotein.
2. It is a trace element.

Final Answer: Protoplasm is formed of Carbon, Nitrogen, Oxygen, and Hydrogen ions.
