Question:
Cyclic electron flow may be photoprotective (protective t light-induced damage). Which of the following experiments could provide information on this phenomenon?
a. using mutated organisms that can grow but that cannot carry out cyclic flow of electrons and compare their abilities to photosynthesize in different light intensities
b. using plants that can carry out both linear and cyclic electron flow, or only one or another of the processes, and measuring their light absorbance
c. using bacteria that have only cyclic flow and look for their frequency of mutation damage
d. using bacteria with only cyclic flow and measuring the number and types of photosynthetic pigments they have in their membranes
e. using plants with only photosystem I operative and measure how much damage occurs at different wavelengths
Answer:
A: using mutated organisms that can grow but that cannot carry out cyclic flow of electrons and compare their abilities to photosynthesize at different light intensities
