If a C3 plant and a C4 plant are placed together in a sealed illuminated box with suffi cient moisture, the C4 plant thrives while the C3 plant sickens and eventually dies. Explain.
Carbonyl cyanide m-chlorophenyl hydrazone (CCCP) is an ionophore that allows the free passage of protons through membranes and is a metabolic poison of mitochondria. A researcher tested CCCP on the green alga Hydrodictyon africanum. Results showed that CO2CO2 fixation was severely inhibited, whereas O2O2 release and production of NADPH were only mildly affected. What is the MOST likely explanation of the results for the inhibition of carbon fixation?
A.
CCCP disrupts the synthesis of ATP at the mitochondrial membrane.
B.
CCCP inhibits splitting of water at the thylakoid membrane.
C.
CCCP inhibits the flow of electrons at the mitochondrial membrane.
D.
CCCP disrupts the synthesis of ATP at the thylakoid membrane.
Give two examples (names) for each: C3, C4 and CAM plants. In what environments do you expect to find a C3, C4 or a CAM plant?

Ironically, plants have embedded in the inner membrane of their mitochondria a protein named the “uncoupling protein” that essentially can carry out the same process caused by dinoseb. The mechanism of uncoupling oxidative phosphorylation involves which of the following scenarios. A. Excess electrons oxidize lipids in the mitochondrial membranes, thus destroying the electron transport chain B. Excessive oxygen is consumed via reduction to water, thus depriving the mitochondria of the ability to carry out phosphorylation that requires oxygen C. The membrane selectivity required to maintain a proton gradient is altered so the potential for driving ATP synthesis via chemiosmosis is degraded D. Uncoupling oxidative phosphorylation kicks a cell into a fermentative pathway that cannot supply sufficient ATParrow_forwardPDHC is an enzyme complex consisting of 3 different enzymes.
