Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
Active transport is the movement of large materials across a cell membrane from ____ to ____ concentration
A
high to low
B
low to high
C
high to high
D
low to low
Explanation: 

Detailed explanation-1: -This is the biological process in which molecules move against the concentration gradient and require chemical energy to move biochemical compounds from a lower region to the high region. Therefore, this process uses ATP – Adenosine triphosphate to pump molecules through a concentration gradient.

Detailed explanation-2: -During active transport, substances move against the concentration gradient, from an area of low concentration to an area of high concentration. This process is “active” because it requires the use of energy (usually in the form of ATP).

Detailed explanation-3: -In cellular biology, active transport is the movement of molecules or ions 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.

Detailed explanation-4: -Osmosis: Osmosis is the movement of solvent particles across a semipermeable membrane from a dilute solution into a concentrated solution.
