From where does the
electron transport
chain get the highenergy electrons that
are passed down the
chain?
ANSWER
BACK TO GAME

NADH and FADH2 molecules.
(The original source of these
electrons is hydrogen atoms
from glucose.)

$500 Answer
The energy is used to actively
transport H+ particles across
the inner mitochondrial
membrane. The concentration
gradient that is created is then
used to power the production
of ATP.

Comparing Photosynthesis
and
Cellular Respiration
FINAL ROUND Question
If photosynthesis is the
process that “deposits” energy
in a “savings account,” then
what is cellular respiration?
ANSWER
BACK TO GAME
FINAL ROUND Answer
Cellular respiration “withdraws” the
energy that was deposited by
photosynthesis and re-invests the
energy into ATP.
