Question

multiple select question select all that apply which statements accurately compare the intermembrane space and the matrix of a mitochondrion? there is a higher concentrations of protons in the intermembrane space compared to the matrix. there is a lower concentrations of protons in the intermembrane space compared to the matrix. the matrix is negative compared to the intermembrane space. the matrix is positive compared to the intermembrane space.

Explanation:

During the electron - transport chain in mitochondria, protons are pumped from the matrix into the intermembrane space. This creates a proton gradient where the intermembrane space has a higher concentration of protons than the matrix. Also, due to the separation of charge by the proton - pumping process, the matrix is negatively charged compared to the positively charged intermembrane space.

Answer:

There is a higher concentrations of protons in the intermembrane space compared to the matrix.
The matrix is negative compared to the intermembrane space.
