Active transport requires energy to move substances across a cell membrane against their concentration gradient, whereas passive transport does not require energy and relies on the concentration gradient. Examples of active transport include the sodium-potassium pump and endocytosis.
Yes, active transport requires transport proteins to move molecules against their concentration gradient, requiring energy in the form of ATP. These transport proteins facilitate the movement of specific molecules across the cell membrane.
This process is called endocytosis, where the cell membrane invaginates to form vesicles that transport materials into the cell. These vesicles can then fuse with other organelles or transport materials to other parts of the cell.
Facilitated diffusion is a form of passive transport that uses transport proteins to facilitate the movement of specific molecules across a cell membrane. These proteins help molecules move down their concentration gradient without requiring energy input from the cell.
One form of active transport is the sodium-potassium pump, which actively transports sodium ions out of the cell and potassium ions into the cell against their concentration gradients, using ATP as energy.
A prow is the front part of a ship. The prow of the boat split the water apart. The prow rammed the iceberg.
