Ion pumps and phagocytosis
WebIon pumps and phagocytosis are both examples of ________. a. endocytosis b. passive transport c. active transport d. facilitated diffusion Expert Solution Want to see the full … WebIon pumps are channels that use the ATP hydrolysis energy to transfer ions from one side of a membrane to the other against their electrochemical gradient (Harold, 1986; Laüger, 1991 ). Similar to passive channels, they are selective, i.e. a pump structure is only adapted to the passage of a particular ion.

Web5 nov. 2024 · Sodium potassium pump; Bulk transport (phagocytosis and pinocytosis) Cell Membrane Transport. The structure of the cell membrane is designed so that it does not allow free movement of substances. However, it is semipermeable due to which certain substances can still move in and out of the cell. WebThis protein uses the energy released from hydrolysis of ATP (adenosine triphosphate) to pump three sodium ions out of and two potassium ions into the cell. ATP is an energy molecule, and when hydrolysis happens, it gets broken down to release the energy that …
