What are the functions of proteins and nucleic acids in the cell?

1. The main function of nucleic acids is storage and transmission of hereditary information (DNA) and participation in protein synthesis (RNA).
2. Functions of proteins:
– construction (membrane proteins);
– catalytic (enzymes);
– signal (formation of nerve impulses);
– protective (antibodies, blood coagulation factors);
– contractile (actin and myosin in muscles);
– transport (hemoglobin);
– regulatory (hormones);
– storage (ovalbumin – egg protein);
– energy (oxidation of 1 g of protein – 17.9 kJ).
