Protons are pumped across the mitochondrial inner membrane as electrons are transferred through the mitochondrial electron transport chain. which of the following statements about proton pumping are correct?
a. protons are pumped into the matrix of the mitochondria. b.the nadh dehydrogenase, cytochrome b-c1, and cytochrome oxidase complexes all pump protons across the membrane. c.the ph inside the mitochondrial matrix is higher than in the intermembrane space. d.the mitochondria use the proton gradient to synthesize atp.

B, C and D

Explanation:

Option A is wrong because protons are not pumped into the matrix of the mitochondria, but rather protons are pumped from the mitochondrial matrix to the inner membrane space.

Option B is correct. The NADH dehydrogenase, cytochrome b-c1, and cytochrome oxidase complexes are all protons pumps and pump protons across the membrane.

Option C. Is correct. The pH inside the mitochondrial matrix is higher than in the innner membrane space.

Option D is correct. The mitochondria use the proton gradient to synthesize ATP by the enzyme ATP synthase.

0 because theres a difference between pickled peppers and peers.

b. read the phase at the intersection of any given temperature and pressure.
