ATP is composed of adenosine and three phosphate groups. Energy is released when its terminal phosphate bond breaks, forming ADP (adenosine diphosphate) and inorganic phosphate. This energy powers cellular activities like muscle contraction, nerve signaling, and biosynthesis.
How ATP works:
Production: Generated via:
Cellular respiration (mitochondria): Glucose breakdown yields ~38 ATP.
Photosynthesis (plants): Converts sunlight into ATP.
Cycle: ATP → ADP + Pi (releases energy); ADP is recycled back to ATP using energy from food or sunlight.
Why it’s called “currency”:
Universally used by all organisms.
Efficiently transfers energy between reactions.
Short-lived but continuously regenerated.
Key roles:
Fuels active transport (e.g., sodium-potassium pump).
Drives anabolic reactions (e.g., protein synthesis).
Supports mechanical work (e.g., muscle movement).
Without ATP, cells couldn’t function. It’s the linchpin connecting energy release (catabolism) and energy use (anabolism), making life possible.
