One of the ways in which ATP is used in the cell is to transport vesicles from the Golgi apparatus to different parts of the cells. Vesicles act like postmen, carrying tagged proteins and lipids from the sorting office (Golgi) to the delivery address (around the cell). The postvan is a tiny motor protein called… Continue reading Why do cells need ATP?
ATP synthase is the enzyme responsible for producing ATP in the last stage of oxidative phosphorylation. This diagram shows a detailed structure of ATP synthase, including the H+ channel through which the H+ ions flow down into the matrix, resulting in ATP production.
