molecular physiology

Molecular physiology studies how molecules like proteins, DNA, and other small molecules function within the body to maintain health and support biological processes. It examines the interactions and mechanisms at a cellular level—such as how enzymes facilitate chemical reactions or how signals are transmitted between cells. This field helps us understand how our bodies operate at a tiny scale, revealing how molecular changes can impact overall health and disease. Essentially, molecular physiology bridges the gap between tiny molecular events and the complex functions of living organisms.
