In order to make the proton gradient, protons are pumped across the mitochondrial membrane at several points in the electron transport chain. However, that proton gradient is only used to make ATP by the ATP synthase, which is technically separate from the electron transport chain.
Ethics are principles that govern a person’s behavior or the conducting of an activity

Answer:
The correct option is<em> A. Active transport moves substances against the concentration gradient.</em>
Explanation:
Active transport can be described as a transport mechanism in which molecules tend to move against the concentration gradient i.e from an area of lower concentration to an area of higher concentration. Energy is needed for this process to occur.
Facilitated diffusion can be described as a phenomenon is which molecules move along the concentration gradient i.e from a higher concentration to a lower concentration with the help of trans- membrane integral proteins
