|
|
H+ ions serve as the final electron acceptor
|
|
|
a concentration gradient is generated when H+ ions are passively transported from the matrix to the intermembrane space of the mitochondrion
|
|
|
energy is released as H+ ions move freely across the mitochondrial membrane
|
|
|
ATP is synthesized when H+ ions move through a channel in ATP synthase
|
Detailed explanation-1: -The process of ATP synthesis using ‘free energy’ obtained when electrons are passed to several carriers (ETC) is known as chemiosmosis. The actual point of the synthesis of ATP takes place when electrons pass the inner mitochondrial membrane. Energy is released within this process, resulting in the synthesis of ATP.
Detailed explanation-2: -As H +start superscript, plus, end superscript ions flow down their gradient and back into the matrix, they pass through an enzyme called ATP synthase, which harnesses the flow of protons to synthesize ATP.
Detailed explanation-3: -Solution: In chemiosmotic synthesis of ATP, H+ diffuses through ATP synthetase from thylakoid space into stroma.
Detailed explanation-4: -ATP synthase complex (FoF1-ATP synthase). This complex allows protons to flow back into the matrix and uses the free energy change from this process to synthesize ATP from ADP and inorganic phosphate (Pi).
