Detailed explanation-1: -Most of the chemical reactions in a cell take place in the cytoplasm. It is a jelly-like substance enclosed by the cell membrane. It consists of all the organelles that carry out speciic functions and all the chemical reactions take place here in cytoplasm.

Detailed explanation-2: -The cell membrane, therefore, has two functions: first, to be a barrier keeping the constituents of the cell in and unwanted substances out and, second, to be a gate allowing transport into the cell of essential nutrients and movement from the cell of waste products.

Detailed explanation-3: -Answer and Explanation: The part of the cell membrane that can catalyze chemical reactions are proteins. Proteins function as catalysts called enzymes and speed up chemical reactions.

Detailed explanation-4: -Lipid membranes that surround each biological cell and its various compartments host chemical reactions of paramount importance for the cell. Proteins embedded in the lipid membrane catalyze chemical reactions, transport ions and larger solutes, and participate in cell signaling pathways.

Detailed explanation-5: -The cytoplasm is the gel-like fluid inside the cell. It is the medium for chemical reaction.
