4. Calculate the energy released by the reduction of O2 with FADH2
1) If we put a photosynthetic organism in a closed, sealed environment and shine a light on it, we observe that the CO2 and O2 levels in the container reach constant levels.
a) Explain why this would occur.
b) What factor/value would you expect to be the primary determinant of this value?
If isolated mitochondria are incubated with asource of electrons such as succinate, but without oxygen,electrons enter the respiratory chain, reducing each of theelectron carriers almost completely. When oxygen is thenintroduced, the carriers become oxidized at different rates(Figure Q14–1). How does this result allow you to order the electron carriers in the respiratory chain? What is theirorder?
