Question

.......... is the site for many biochemical reactions necessary to sustain life.

• A. Cytoplasm
• B. Ribosome
• C. Cell membrane
• D. Cell wall

Answer 1

The correct option is A Cytoplasm

Ribosomes are cell organelles, which are present in free or in bound form. They are involved in the synthesis of proteins.
The cell membrane is the outer covering of the cell, which protects the cell. It also supports the framework of the cell.
The cell wall is a protective outer covering of the cell. It supports the contents of the cell and protects from pathogen attack and wear and tear. It is made of cellulose, lignin.

Cytoplasm is a gel-like substance present in all cells. All of the cell organelles are suspended in the cytoplasm. Most of the cellular activities as metabolic pathways like glycolysis, key processes like cell division occur in the cytoplasm. Hence, it is the place, where life-sustaining biochemical reactions occur. Thus, the correct answer is option A.
