What is the reaction that rubisco catalyzes? Why is rubisco the key enzyme for producing the worlds food, and how is it the key regulatory site of the Calvin cycle?
Figure 27.3 illustrates the response of R (ATP-regenerating) and U (ATP-utilizing) enzymes to energy charge. a. Would hexokinase be an R enzyme or a U enzyme? Would glutamine: PRPP amidotransferase, the second enzyme in purine biosynthesis, be an R enzyme or a U enzyme? b. If energy charge = 0.5: Is the activity of hexokinase high or low? Is ribose-5-P pyrophosphokinase activity high or low? c. If energy charge = 0.95: Is the activity of hexokinase high or low? Is ribose-5-P pyrophosphokinase activity high or low?
In 1976, a team of chemists in the United Kingdom was developing new insecticides by modifying sugars with chlorine Cl2, phosgene Cl2CO, and other toxic gases. One young Member of the team misunderstood his verbal instructions to test a newly made candidate substance. He thought he had been told to taste it. Luckily for him, the substance was not toxic, but it was very sweet. It became the food additive sucralose. Sucralose has three chlorine atoms substituted for three hydroxyl groups of sucrose table sugar. It binds so strongly to the sweet-taste receptors on the tongue that the human brain perceives it as 600 times sweeter than sucrose. Sucralose was originally marketed as an artificial sweetener called Splenda, but it is now available under several other brand names. Researchers investigated whether the body recognizes sucralose as a carbohydrate. They began by feeding sucralose labeled with 14C to volunteers. Analysis of the radioactive molecules in the volunteers urine and feces showed that 92.8 percent of the sucralose passed through the body without being altered. Many people are worried that the chlorine atoms impart toxicity to sucralose. How would you respond to that concern?
What do the electrons added to NAD do? a. They become part of a fermentation pathway. b. They go to another pathway for ATP production. c. They energize the entry of the acetyl group into the citric acid cycle. d. They are converted into NADP.
Which of the following pathways requires molecular oxygen (O2)? a. aerobic respiration b. lactate formation c. alcoholic fermentation d. photosynthesis
Yeast is a facultative anaerobe. This means that alcohol fermentation takes place only if: the temperature is close to 37°C the atmosphere does not contain oxygen sugar is provided to the cells light is provided to the cells
Catalase combines two hydrogen peroxide molecules (H2O2+H2O2) to make two molecules of water. A gas also forms. What is the gas?
The normal enzyme required for converting sugars into glucose is present in cells, but the conversion never takes place and no glucose is produced. What could have occurred to cause this defect in a metabolic pathway?
Describe nitrogen fixation and why it is important to agriculture.
Which statement correctly describes carbon fixation? the conversion of CO2 into an organic compound the use of RuBisCO to form 3-PGA the production of carbohydrate molecules from G3P the formation of RuBP from G3P molecules the use of ATP and NADPH to reduce CO2
In what form is energy transferred in a redox reaction?
Melvin Calvin and Andrew Benson determined the steps in the light-independent reactions of photosynthesis by exposing the green alga Chlorella to CO2 labeled with the radioisotope carbon 14. By looking at which compounds the C14 ended up in, they were able to identify all intermediates in this cyclic pathway. Why did they predict correctly that the same set of intermediates would be formed in the light reaction in land plants?
