Answer:
The final electron acceptor of the electron transport chain is oxygen
Explanation:
Four electrons gotten from cytochrome c are involved in the conversion of a molecule of oxygen (O2) to two molecules of water (H2O). This final electron transfer occurs in complex IV. Complex IV, also known as cytochrome c oxidase, facilitates the the use of four protons from the matrix of the mitochondrion, in the production of water molecules while pumping four protons to the intermembrane space of the mitochondrion.
It would be F only because I wouldn’t make sense CI doesn’t exhibit crystalline neither does BR so F

Answer:
6.94 × 10⁴ J
Explanation:
We can calculate the work (W) associated with the compression of a gas at constant pressure using the following expression:
W = -P . ΔV
where,
P is the external pressure
ΔV is the change in the volume
Knowing that 1 atm.L = 101.325 J, the work of compression is:
The positive sign of the work means that the surroundings do work on the system.
