The correct answer is: Protons are pumped out of the mitochondrial matrix into the intermembrane space
Chemiosmosis can be described as movement of ions across a selectively permeable membrane, down their electrochemical gradient. It occurs during the cellular respiration within mitochondria and it is involved in ATP synthesis (oxidative phosphorylation via ATP synthase).
Electrons from electron carriers (NADH and FADH) donate electrons to the electron transport chain and that causes changes in protein complexes of electron transport chain. As a consequence, protein complexes pump H+ across a selectively permeable cell membrane from the mitochondrial matrix into the intermembrane space of mitochondria.
H+ can only get back and pass through the inner mitochondrial membrane with the help of ATP synthase (down their electrochemical gradient). ATP synthase turned by the force of the H+ diffusing through it forms ATP by adding a phosphate to ADP.
An isolated colony on a selective medium is not considered a pure culture because inhibited organisms might be masked by the colonies. This statement is true.
On the basis of their constitution or usage, culture media can be classified into various groups; these include defined, complex, selective, as well as enrichment medium.
A selective medium consists of dyes or noxious substances/chemicals which inhibit the growth of specific microorganisms but promote the growth of other microbes.
A pure culture is a laboratory culture which contains a single species of microorganism. It is free from other microorganisms.
Since selective media affects the growth of distinct organisms differently, therefore, an isolated colony formed in such type of medium is not considered a pure culture.

Q+ZT -> Z+QT
hoping that's correct or are there any answer choices?
Answer:
○ D. Humans are using up natural capital faster than it is being replenished.
Explanation:
I assume this is the answer, due to the past/recent media on Earth and the economy.
