Question

Select the correct statement regarding active ion uptake, which differentiate it from secondary

Answer 1

As there are no options given so, i'm providing a few basic differences:

(i) Active ion uptake uses the ATP's as energy source whereas secondary ion uptake relies upon the Electrochemical potential difference.

(ii) Active uptake occurs from lower concentration to a region of higher concentration and secondary uptake occurs from region of higher concentration to lower concentration.

(iii) Absorption of glucose in human intestines is an example of Active uptake and Electron Transport Chain in Mitochondrion of plant cells is an example of secondary ion uptake.
