Answer
The processes and roles of "chemiosmosis" and "ATP synthase" in the mechanism of ATP generation
Solution
a
Chemiosmosis: This process involves the movement of ions (specifically hydrogen ions, H⁺) across a selectively permeable membrane, down their electrochemical gradient. In cellular respiration, this occurs in the mitochondria, where the electron transport chain creates a proton gradient across the inner mitochondrial membrane
b
ATP Synthase: This enzyme is embedded in the inner mitochondrial membrane and utilizes the energy from the proton gradient created by chemiosmosis to synthesize ATP from ADP and inorganic phosphate (Pi). The flow of protons through ATP synthase drives the rotational mechanism of the enzyme, facilitating the production of ATP
Key Concept
Chemiosmosis and ATP synthase are crucial for ATP generation in cellular respiration.
Explanation
Chemiosmosis creates a proton gradient that provides the energy for ATP synthase to produce ATP, the primary energy currency of the cell.
