ATP (Adenosine Triphosphate)

Definition

ATP, or Adenosine Triphosphate, is a molecule that provides energy for many processes in living cells, making it essential for various bodily functions and exercise.

Scientific / Technical Definition

Adenosine Triphosphate (ATP) is a complex organic chemical that provides energy to drive many processes in living cells. It consists of an adenine base attached to a ribose sugar, which is further connected to three phosphate groups. The energy released during the hydrolysis of ATP drives various cellular processes, including muscle contraction, nerve impulse propagation, and chemical synthesis.

Benefits

• Provides energy for cellular functions
• Supports muscle contraction during exercise
• Facilitates metabolic processes
• Aids in the transportation of macromolecules across cell membranes

Examples

• Mitochondria produce ATP in cells
• ATP is used during muscle contraction in activities like running and weightlifting

Additional Information

• Effects: ATP is critical for nearly all physiological processes and is known as the 'energy currency' of the cell.
