Question

what would happen if the concentration of h+ ions were higher inside the mitochondrion than outside the mitochondrion when the channel opened?
a. more h+ ions would be created.
b. h+ ions would flow into the mitochondrion.
c. h+ ions would not flow.
d. h+ ions would flow out of the mitochondrion.

Explanation:

Step1: Understand diffusion principle

Ions move from high - to low - concentration.

Step2: Analyze ion concentration

Given higher H⁺ concentration inside mitochondrion.

Step3: Determine ion flow

When channel opens, H⁺ ions flow out to equalize concentration.

Answer:

D. H⁺ ions would flow out of the mitochondrion.
