question 82

Multiple Choice

In the lab you isolate a chlorella mutant that is unable to switch xanthophyll pigments into the inactive, non-heat-dissipating form. If you released that mutant into a small pond shaded by trees, would the mutation spread, and why?

• A)No, because the light absorbed by chlorophyll would be released as heat and thus not used to make ATP or NADPH.
• B)No, because the xanthophylls prevent the production of reactive oxygen species.
• C)Yes, because the xanthophylls prevent the production of reactive oxygen species.
• D)Yes, because the heat released by the xanthophylls would warm up the cells and enhance photosynthesis.
