chemiosmotic theory
Quick Summary
The chemiosmotic theory explains how cells generate adenosine triphosphate (ATP), the primary energy currency. This theory, proposed by Peter Mitchell, states that the energy released from electron transport chains in mitochondria and chloroplasts is used to pump protons across a membrane. This creates an electrochemical gradient, a form of potential energy. As protons flow back across the membrane through an enzyme complex called ATP synthase, the energy is harnessed to synthesize ATP from ADP and inorganic phosphate. This process is crucial for cellular functions, powering various biochemical reactions necessary for life.12345
