Question

what do you mean by the active transportation across the membrane of a cell please explain in very detail ???

Answer 1

⭐To sustain life or for survival many substances need to be transported into or out of and between cells.

⭐Cell membranes are semipermeable which means that they have control over what molecules can or cannot pass through the cell membrane .

⭐It is the term which is used to describe the processes of moving materials through the cell membrane that requires the use of energy.


⭐ There are three main types of Active Transport that is

✨The Sodium-Potassium pump.

✨Exocytosis

✨Endocytosis.


⭐Active transport requires the assistance of a type of protein called a carrier protein that uses energy supplied by ATP.


⭐FURTHUR:--

➡Active transport is the movement of molecules across a membrane from a region of their lower concentration to a region of their higher concentratioN.

⭐basically , To move substances against a concentration that requires a cell must use energy.

Answer 2

$\huge\mathfrak\red{Answer:}$

Active transport is the movement of molecules across a cell membrane in the direction against their concentration gradient, going from a low concentration to a high concentration.

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. Secondary active transport involves the use of an electrochemical gradient. Active transport uses cellular energy, unlike passive transport, which does not use cellular energy. Active transport is a good example of a process for which cells require energy.
