Answer 1

1. Proteins are large biomolecules that are made up of amino acid residues. They are synthesised in cells by translation of the genetic material coded in the genes.

These proteins serve a majority of functions inside the cells, like:

a) Helps in structural formation of the cell membrane and provides fluidity to the cell membrane.

b) These proteins act as enzymes (catalysts) and enhance the rate of various reactions.

c) The proteins found in the cell membrane also serve the purpose of gates and allow the entry of selected molecules into and out of the cell.
