The role played by the inner mitochondrial membrane in producing ATP is as follows:
• The inner mitochondrial membrane comprises electron transport proteins. At the inner mitochondrial membrane, a high-energy electron is passed via an electron transport chain.
• This released energy pumps hydrogen out of the matrix space, resulting in the formation of a gradient.
• This gradient pushes hydrogen ions back through the membrane, with the help of ATP synthase.
• With this, the enzymatic activity of ATP synthase generates ATP from ADP.
