Process of Electron Transport Chain (ETC), is a series of transferring from electron donors to their acceptors. It basically means a transfer from high energy molecule to a low-energy molecule. This process of extracting energy by transfer is classified as a chemical reaction and we see it is the path taken of cellular respiration (NADH) and FADH2) and in photosynthesis, NADPH. It starts with an electron, NADH and FADH2, when the electron donors release a proton gradient and it creates an imbalance. Think of it as a see-saw with one heavy person on one end and a lighter one on the other end. The protons actually attempt to defuse back across this see-saw of a membrane and it releases energy during the cross over which we call Chemiosmosis.
Answer:
The rock cycle is a constant transformation of rocks between the three rock types of igneous, sedimentary, and metamorphic. If the sediments are buried behind other layers of sediment, they can lithify and form sedimentary rock. When rocks melt, magma is formed. Rocks form deep below the Earth, move and sometimes change, rise to the surface, and eventually return to their original location.
