Answer:
Concentration gradient means difference in solute concentration among two regions of a solution.
Explanation:
When there is a difference in solute concentration in the two regions of a solution then the term concentration gradient is used .
Various membrane transport process such as passive transport(diffusion and osmosis),facilitate transport depends on concentration gradient of solute molecule in both sides of plasma membrane.
During passive and facilitate diffusion solute molecules are transported along their concentration gradient that means from high concentration region to the region of low concentration until equilibrium is being established.
The one that is loosing electron is oxidation process and the one that is gaining electron is reduction.
b) Reduction reaction occur at cathode while oxidation reaction occur at Anode.
Explanation:
The main difference between the reduction and oxidation process is based on gaining and loosing of electron.
Reduction and oxidation both occur simultaneously. one is loosing electron and other is gaining. The one that is loosing electron is oxidation process and the one that is gaining electron is reduction.
B) Reduction reaction occur at cathode while oxidation reaction occur at Anode
