|
active transport
|
|
|
diffusion
|
|
|
osmosis

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