what is active transport across cell membrane ??
Answers
Answer :----
⭐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.

⭕.⚫Active Transport is the term used to describe the processes of moving materials through the cell membrane that requires the use of energy.
⚫.⭕There are numerous situations in living organisms when molecules move across cell membranes from an area of lower concentration toward an area of higher concentration.
This is counter to what would be expected and is labeled "active transport".
⚫.⭕ There are times when membranes are impermeable to some molecules because of their size, polarity, etc. and only the smaller solvent molecules like water molecules will move across the membrane.
There are three main types of Active Transport:
✴ The Sodium-Potassium pump
✴Exocytosis
✴Endocytosis
