Answer:
My favorite animal is a cheetah. I have three reasons of liking the cheetah with consists of these fine abilities/skills/cool things. I like how the cheetah has a really pretty coat of spots and speckled with really makes it stand out and look different. I also like that the cheetah is lightning fast, but it's sad it can only run 60-70 miles per hour for a short period of time. I Also like that cheetahs can be in zoos and also can be trained, petted, and can also (rarely) have babies. Cheetahs need to be saved because they are starting to get really rare and endangered.

Answer:
D) In case 1, both PS I and PS II completely lose function; in case 2, a proton gradient is still produced.
Explanation:
The light dependent reaction of photosynthesis, which produces the ATP and NADPH needed in the light independent stage of the process, includes complexes of proteins and pigments called PHOTOSYSTEMS. These photosystems (I and II) are key to the functionality of the light dependent reactions in the thylakoid.
The major pigment present in both photosystems is CHLOROPHYLL A, which absorbs light energy and transfers electrons to the reaction center. Chlorophyll B is only an accessory pigment meaning it can be done without. Hence, if all of the chlorophyll A is inactivated in the algae but leaves chlorophyll B intact as in case 1, both PS I and PS II will lose their function because Chlorophyll A is the major pigment that absorbs light energy in both photosystems.
In case 2, if PS I is inhibited and PS II is unaffected, a PROTON GRADIENT WILL STILL BE PRODUCED because the splitting of water into protons (H+) and electrons (e-) occurs in PSII. Hence, H+ ions can still be pumped into the inner membrane of the thylakoid in order to build a proton gradient even without the occurrence of PS I.
