Question

What is active transport ​

Answer 1

Answer:

In cellular biology, active transport is the movement of molecules across a cell membrane from a region of lower concentration to a region of higher concentration—against the concentration gradient. Active transport requires cellular energy to achieve this movement

Explanation:

Active transport is a kind of cellular transport where substances move against a concentration gradient. This means that the direction is from an area of lower concentration to an area of higher concentration. Hence, this process will require expenditure of energy, and the assistance of membrane proteins, such as carrier proteins.

Answer 2

Answer:

•Active transport is the energy-requiring process of pumping molecules and ions across membranes against a concentration gradient.

•Active transport processes help maintain homeostasis.
