The final electron acceptor of the electron transport chain that functions in aerobic oxidative phosphorylation is
labwork [276]

Answer: a. oxygen

Basically what (/the) ETC and oxidative phosphorylation is, is the products of the Krebs cycle being oxidized and oxygen receiving electrons. And when the phosphorylation part of oxidative phosphorylation occurs is when ADP gains its third phosphate group becoming ATP.

Forgive me for this poor response I was trying to be quick and it resulted in this vague and disorganized mess. To properly explain the ETC and oxidative phosphorylation it would be best to start from the beginning and explain all the stages of Aerobic respiration.

What happens as a result of osmosis when an animal cell containing 1% sugar is placed in pure water
Mama L [17]

The process of osmosis is the movement of water through a selectively permeable membrane from an area of higher concentration to an area of lower concentration.

If 1% sugar solution is placed in pure water, then there would be a higher concentration of water molecules outside the cell compared to inside the cell. The solution outside the cell would be hypo-tonic (containing fewer solute molecules than inside the cell). Water will move into the cell by inward osmosis and the cell would then swell.
