Cellular Respiration and Photosynthesis Problem Solving

1. Fill in the table below to compare and contrast glycolysis, pyruvate oxidation, citric acid cycle, oxidative
   phosphorylation. I have filled in pyruvate oxidation using the information in section 7.3 and figure 7.7 as an
   example.
2. The reactions of the Calvin cycle used to be referred to as the “dark reactions” of photosynthesis implying
   that light was not required. However, experimental evidence demonstrates that in the absence of light the
   Calvin cycle shuts down. Why does this happen?
3. Brown fat is a type of adipose tissue that is most abundant in infants and hibernating animals. Brown fat
   mitochondria have proton channels located in their inner membranes. What effect does the proton channel
   have on oxidative phosphorylation in brown fat cells? Why would this be beneficial to hibernating animals?
