Detailed explanation-1: -Which process temporarily disrupts homeostasis because it increases an already high concentration of chemicals in the cell? Active transport though membrane proteins.

Detailed explanation-2: -Active transport is usually associated with accumulating high concentrations of molecules that the cell needs, such as ions, glucose and amino acids. If the process uses chemical energy, such as from adenosine triphosphate (ATP), it is termed primary active transport.

Detailed explanation-3: -Diffusion is the movement of molecules from an area of high concentration of the molecules to an area with a lower concentration. For cell transport, diffusion is the movement of small molecules across the cell membrane.

Detailed explanation-4: -Types of active transport include ion pumps, such as the sodium-potassium pump, and vesicle transport, which includes endocytosis and exocytosis. Cell transport helps cells maintain homeostasis by keeping conditions within normal ranges inside all of an organism’s cells.

Detailed explanation-5: -Homeostasis and Cell Function Keeping a stable internal environment requires constant adjustments as conditions change inside and outside the cell. The adjusting of systems within a cell is called homeostatic regulation.
