What is the final acceptor of electrons in the electron transport chain?

The final acceptor of electrons in the electron transport chain is "C" , that is oxygen.

The electron transport chain is composed of a series of electron carriers that operate together to transfer electrons from donors, like NADH and FADH2, to acceptors such as O2.

The electrons flow from carriers with more negative reduction potentials to those with more positive potentials and eventually combine with O2 and H+ to form water.

The difference in reduction potentials between oxygen and NADH is large, about 1.14 volts and makes possible the release of a great deal of energy.

Does cellular respiration occur in plants

Simora [160]

Cellular respiration occurs in both plant and animals. It is the process by which cells convert ADP (adenosine diphoosphate) into ATP (adenosine triphosphate).Plant and animal cells cannot use ADP as a form of energy. The mitochondria within the cells convert ADP into a useable form of cellular energy: ATP.

Explain how sediments eroded by the water in this stream become smoother and rounder in shape

bonufazy [111]

The sediments rub together to become smoother. Sediments which are transported in a mass by water or stream are in motion with respect to the motion of the stream water. They bump into each other which makes extruding parts vulnerable to getting knocked off which makes these particles round after a while.
