Endocytosis is the provess used by the cell to bring in large molecules.
The process that brings food into the cell during active transport is called endocytosis. This involves the cell membrane engulfing and forming a vesicle around the food particles to bring them into the cell. Once inside the cell, the vesicle fuses with other cellular components for further processing.

During active transport in the sodium-potassium pump, three sodium ions are pumped out of the cell while two potassium ions are pumped into the cell against their concentration gradients, using energy from ATP.
Active transport is the movement of a substance across a cell membrane using chemical energy. This process requires the use of a carrier protein and ATP to transport molecules against their concentration gradient.

ATP is often used as the source of energy during active transport.
Active transport requires the use of energy, usually in the form of ATP, to move molecules or ions across a cell membrane against their concentration gradient. This process is essential for maintaining cell functions and often involves specific transport proteins or pumps.
During active transport, a cell must expand its energy in the form of ATP to pump molecules or ions across a membrane against their concentration gradient. This process requires energy to create a concentration gradient and move substances from low to high concentration.
During active transport in the sodium-potassium pump, three sodium ions are pumped out of the cell while two potassium ions are pumped into the cell against their concentration gradients, using energy from ATP.
ATP
ATP (adenosine triphosphate) is used during active transport but not passive transport. Active transport requires energy to move substances against their concentration gradient, while passive transport relies on diffusion to move substances down their concentration gradient without the need for energy.
