True and False
1. Exposure to light, temperatures above 40°F, andoxygen will increase the rate of pigment discoloration and lipid rancidity, which areoxidative chemical processes.
2. The Fe-S clusters in the ETC accept electrons but not protons fromthe preceding step.
3. Nitrogen fixation represents aprocess by which atmospheric nitrogen oxidized to make 2 ammoniumions.
4. In a mitochondrion, the TCAcycle cannot continue on indefinitely without oxgen because the electron transportchain will be incapable of oxidizing NADH and FADH2.
5. When you inhale, you take in O2. What is the chemical fate of these oxygen atoms?
