Question
1. You must water a plant not only to keep it hydrated but to provide a source of electrons for the light reactions.
a.) True
b.) False
2. Buildup of the pH gradient can occur in the electron transport chain of photosynthesis even when the electron transport is abolished.
a.) True
b.) False
3. Elimination of the proton gradient in the chloroplast will result in failure to produce ATP.
a.) True
b.) False
4. The pH gradient established by the electron transport chain in photosynthesis:
a.) Exists between the matrix and the mitochondrial intermembrane space
b.) Sets up a voltage gradient that drives GTP formation
c.) Is established by electron transfer from FADH2 and NADPH from the TCA
cycle to oxygen
d.) Occurs in part because Fe-S clusters can only transport electrons and not protons
e.) None of the above
Explanation / Answer
1. True
Plants need water for following two process:-
A) germination:-finition: it involves seeds or spores to form new tissue following increased metabolism.
B) photosynthesis:-it involve synthesis of organic compounds using carbon dioxide and water (accompany release of oxygen) using light energy absorbed by chlorophyll.
