The alternative pathways of photosynthesis using the C4 or CAM systems are said to be compromises Why?
a) c4 compromises on water loss and CAM compromises on photorespiration
b)each one both minimizes photorespiration and optimizes the calvin cycle
c)c4 plants allow less water loss but Cam plants allow more water los
d)Cam plants allow more water loss, while c4 plants allow less CO2 into the plant
e) each one minimizes both water loss and rate of photosynthesis
P680+ is said to be the strongest biological oxidizing agent. Why?
a)it is the receptor for the most excited electron in either photosystem
b)NADP reductase will then catalyze the shift of the electron from Fd to NADP+ to reduce it to NADPH
c)This molecule results from the transfer of an electron to the primary electron acceptor of photosystem II and strongly attracts another electron
d)it is the molecule that transfers electrons to plastoquinone (Pq) of the electron transfer system.
e)this molecule is found far more frequently among bacteria as well as in plants and plantlike Protists
For each molecule of glucose that is metabolized by glycolysis and the citric acid cycle, what is the total number of NADH+FADH2 molecules produced?
a)5
b)4
c)6
d)12
e)10
