Question

g Electron flow down the electron-transport chain leads to the transport of proteins: Group of answer choices from the matrix to the intermembrane space NONE OF THESE from the intermembrane space to the matrix from inside the mitochondria to the outside from outside the mitochondria to the inside

Answer 1

from the intermembrane space to the matrix

Step-by-step explanation:

In the electron transport chain (ETC), electrons flow from one protein complex to another. However, as this electrons are transfered, protons (H+) is built up from the intermembrane space of the mitochondria to the mitochondrial matrix.

Hence, according to this question, a proton gradient is formed when hydrogen ions (H+) are moving from the intermembrane space to the matrix of the mitochondrial.
