What happens when an electrical gradient and a chemical gradient are applying opposite forces to active transport?
Ierofanga [76]

Answer:

Option B, they negate each other

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.
