Question

What happens when an electrical gradient and a chemical gradient are applying opposite forces to active transport?

A) they strengthen each other
B) they negate each other
C) they triple the strength of each other
D) they weaken the power of each gradient by half

Answer 1

B) they negate each other

Step-by-step explanation:

The combined effects of electrical and chemical gradients lead to the formation of an electrochemical gradient. This simply means that both an electrical gradient and a chemical gradient can have an effect on the movement of substances, and that their effects may combine (the chemical and electrical gradients encourage movement in the same direction), or they may negate (one gradient opposes another).

Answer 2

Option B, they negate each other

Step-by-step explanation:

Electrical gradient force is more or less equal to the chemical gradient during an active transport. The number of electron produced during the establishment of chemical gradients, were transferred through the cellular circuit to produce electrical gradient of an equivalent amount in opposite path.

Thus, both electrical and chemical gradient are opposite to each other and hence they negate out each other.
