Question
Chapter 5, Problem 5SA
Summary Introduction
To explain: The reason behind oxygen level measurement provides an indication rate of photoreaction and describes how the plant can use carbon dioxide provided by bicarbonate solution, as well as explain how increasing carbon dioxide source affects the rate of photoreaction in plants.
Introduction:
Photosynthesis is a biochemical process in which plants capture light energy and through a series of reactions produce organic energy molecules that later fuel the reactions of fixing atmospheric carbon dioxide and water into organic food molecules.

In chloroplasts, the light reactions power the creation of ATP via chemiosmosis. In relation to this process, which of the following is true?
a) ATP synthase breaks ATP down into ADP, creating energy to fuel chemiosmosis.
b) Oxygen is used as a source of electrons to replace those lost in photosystem II.
c) Chemiosmosis during the light reactions is also used in the reduction of NADPH and FADH2.
d) As excited electrons fall back down to a lower energy state, they create a proton gradient that is used to fuel the phosphorylation of ADP.
If a plant is removed from its natural environment and exposed to 100 percent CO2 composed of the radioisotope 14C, which of the following will not occur?

- In the photosynthesis lab, a group of students found that in the blue light condition, there was a change in absorbance (ΔA620) of 0.324 in extracted spinach chloroplasts. The students later went on a hike and located a plant they had never seen before and were interested in how the photosynthesis rates would compare to their experiment with spinach chloroplasts. They extracted chloroplasts of the unknown green-leaved plant and exposed them to the same experimental conditions as before. The students calculated the ΔA620 to be 0.100.
