Acell's work is carried out by the many different types of molecules it assembles. are especially important because they are involved in a variety of processes, such as cell signaling, immune response, and enzyme activity. a. lipids b. proteins c. nucleic acids d. carbohydrates

Proteins.

Explanation:

Protein is one of the most important biomolecule of the living organisms. Proteins are made up of the polymers of the amino acids. These are the primary building block of the body.

Proteins are involved in the assembly of different molecules. Proteins are involved in the immune response initiation, the enzymatic activity and the cell signalling of the molecules.

Thus, the correct answer is option (B).

oxygen = 21% of the atmosphere

nitrogen = 78%

carbon dioxide = 0.1%

argon =0.934%
