Final answer:
The proton gradient generated by electron transport consists of an ion gradient and a voltage gradient.
Step-by-step explanation:
True. The proton gradient generated by electron transport consists of two components an ion gradient and a voltage gradient. As electrons flow through the electron transport chain, protons are pumped across the membrane from the matrix to the intermembrane space. The uneven distribution of protons establishes both a concentration and electrical gradient, forming the proton gradient.
