List two ways that a fuel cell differs from an ordinary battery

Biology

Alecsey [184]2 years ago

The simple answer is that in a battery the chemical reactions that produce the electrical current are produced from materials that are already in the battery itself, whereas in a fuel cell, the reactants, almost always Hydrogen and Oxygen are fed to the cell like an external fuel.

. However, while a battery makes electricity from the energy it has stored inside the battery, a fuel cell makes its electricity from fuel in an external fuel tank This means that while a battery may run dead, a fuel cell will make electricity as long as fuel is supplied. For hydrogen fuel cells, hydrogen is the fuel and it's stored in a tank connected to the fuel cell. When hydrogen in the tank runs low, you refill it, or replace it with a full tank.

Which statement is most accurate concerning how photosystem II compares to the electron transport chain (ETC) of mitochondria? I
nordsb [41]

The correct answer is: In both systems, ATP is produced by chemiosmosis.  

Both of the processes, photosynthesis and electron transport chain in mitochondria use chemiosmosis (movement of ions across a semipermeable membrane, down their electrochemical gradient) to produce energy or ATP (via ATP synthase). The movement of hydrogen ions across the thylakoid membrane in order to galvanize the production of ATP is equal to the movement of those ions across the inner mitochondria membrane. Electrons are accepted by NADPH in photosynthesis (but not FADH2 as in mitochondria).
