1) In humans they help our bodies to repair, regulate, and protect themselves. Proteins help in the building and repair of tissues, and in body processes such as water balancing, nutrient transport, and muscle contractions. Many essential enzymes and hormones are proteins.Enzymes are proteins that catalyze chemical reactions. Enzymes speed up the reactions in biological systems by lowering the activation barrier needed to start that reaction.Proteins are basically essential for life.
2) Biochemical processes are the chemical processes that occur in living organisms, involving biomolecules. Biomolecules are organic molecules produced by organisms
