TRUE OR FALSE
A coupled reaction is a pair of reactions, one exothermic and one endothermic.
ATP contains less energy than ADP.
In the ATP-ADP cycle, when the phosphate is removed, energy is released.
In coupled reaction, an endothermic reaction supplies the energy needed to drive an exothermic reaction.
Chlorophyll absorbs green light.

Many commercial herbicides act by inhibiting photosynthetic electron transport. They are investigating three herbicides for potential inhibitors of photosynthetic electron transport.
a) How can you determine whether these substances have an inhibitory effect on photosynthetic electron transport? How can you quantify the effect?
b) An inhibitor has produced a strong effect in "in vitro" tests, but the effect is significantly less in "in vivo" tests. What can be the reason for the reduced effect "in vivo"?

The hydrogen added on the end of the formula is an indication that NAD has been reduced. As you read in the textb0ook section on oxidative phosphorylation, a series of redox reactions oxidize NADH back to NAD. All redox reactions are paired oxidation and reduction reactions, so what was reduced? Ultimately O2 is reduced to H2O (note the addition of hydrogen due to reduction). Oxygen is said to be the final electron acceptor, as no further redox reactions take place. In lab we will again look at differences among bacteria in their metabolism as a way to distinguish different species. First we will look at anaerobic respiration. When oxygen levels are low, some microbe can use a different compound than oxygen as their final electron acceptor. Sulfate SO,, carbonate CO3²", and nitrate NO; are all common alternatives, rich in oxygen, which can accept those electrons.…arrow_forward
