Answer:

A. A person descending a flight of stairs one step at a time.

Explanation:

Electron transport chain consists of electron carrier proteins through which movement of electrons from electron donor to the electron acceptor occurs. The energy released by downhill electron transport is conserved in form of electrochemical potential by uphill transport of protons across the impermeable membrane. The downhill flow of protons serve as energy source for ATP synthesis. Hence, the electron transport chain harness the energy of reduced NADH and FADH2 in step by step manner.

Answer:

Motor nerves

Explanation:

Pulling the leg quickly from the sharp object is an example of reflex action. It includes sensory receptors, sensory neurons, interneurons, the control center (spinal cord), motor neurons and effector.

As soon as she steps on the glass piece, the receptors present in the skin of her foot sole sense it and send the information to the control center via sensory neurons. The spinal cord commands the muscles of the effector organ (leg) via motor neurons to move to step away from the glass piece.
