Question
Biology Question on Cell: the unit of life
Movement and accumulation of ions across a membrane against their concentration gradient can be explained by
A
Facilitated Diffusion
B
Passive Transport
C
Active Transport
D
Osmosis
Answer
Active Transport
Explanation
Solution
Active transport is a cellular process that requires energy (usually in the form of ATP) to move ions or molecules against their concentration gradient, from a region of lower concentration to a region of higher concentration. This process allows cells to maintain specific ion concentrations inside and outside the cell, which is essential for various cellular functions.
Therefore, The correct option is (C): Active Transport
