- You have isolated a previously unstudied protein, identified its complete structure in detail and determined that it catalyzes the breakdown of a large substrate. You notice it has two binding sites. One of theses is large, apparently the bonding site for the large substrate; the other is small, possibly a binding site for a regulatory molecule. What do these finding tell you about the mechanism of this protein?
- With respect to the enzyme that converts X to Y, substance A functions as _____.
- What is substance X?
- In the figure, why does the reaction rate plateau at higher reactant concentrations?
- A noncompetitive inhibitor decreases the rate of an enzyme reaction by____.
- According to the induced fit hypothesis of enzyme catalysis, ______.
- The lock-and-key analogy for enzymes applies to the specificity of enzymes____.
- Which of the following is true of enzymes?
- What compound provides the reducing power for Calvin cycle reactions?
- Which of the following does NOT occur during the Calvin cycle?
- Which of the following sequences correctly represents the flow of electrons during photosynthesis?
- Refer to the figure. If the carbon atom of each of the incoming CO2 molecules is labeled with a radioactive isotope of carbon, which organic molecules will be radioactively labeled after one cycle?
- In the process of carbon fixation, RuBP attaches a CO2 to produce a six-carbon molecule, which is then split to produce two molecules of 3-phosphoglycerate. After phosphorylation and reduction produces G3P, what more needs to happen to complete the Calvin cycle?
- What is the primary function of the Calvin Cycle?
