Biochemical energy refers to the energy stored in the bonds of chemical compounds, particularly in biological molecules like carbohydrates, fats, and proteins. This energy is released during metabolic processes, allowing organisms to perform essential functions such as growth, movement, and reproduction. In living cells, biochemical energy is often stored in the form of adenosine triphosphate (ATP), which acts as a universal energy currency. When ATP is broken down, it releases energy that powers various cellular activities, including muscle contraction and nerve impulse transmission. This process is vital for maintaining life and supporting biological systems.
