1.What does ΔG of a metabolic reaction measure? the net change in free energy during a reaction the amount of heat energy gained or lost in a reaction the amount of matter transferred in a reaction the change in activation energy required in a reaction due to enzyme activity the activation energy of a reaction 2. Which of the following does a catalyst change during a chemical reaction? the free energy of the products heat entropy activation energy the free energy of the reactants 3. ATP is not the only molecule that can drive reactions. When ATP is depleted during exercise, muscle cells use phosphocreatine to drive the regeneration of ATP. Consider the following half reactions: 1. ATP + H2O → ADP + Pi ΔG = -7.3 kcal/mol 2. Phosphocreatine + H2O → creatine + Pi ΔG = -10.3 kcal/mol From these two reactions, calculate the Gibbs free energy of the following coupled reaction, catalyzed by creatine kinase: Phosphocreatine + ADP → ATP + creatine ΔG = ? Which is the correct net Gibbs free energy of the reaction? ΔG = -3 kcal/mol ΔG = -17.6 kcal/mol ΔG = 0 kcal/mol ΔG = +3 kcal/mol ΔG = +17.6 kcal/mol 4. Which source of energy does active transport use? the regeneration of ATP bound to an active transport pump the hydrolysis of ATP bound to an active transport pump the hydrolysis of GTP bound to the active transport pump the transport of ATP bound to an active transport pump the transport of GTP bound to an active transport pump 5. Which is an anabolic process? protein synthesis glycolysis ATP hydrolysis protein degradation active transport 6. The sodium-potassium pump is an active transport pump that uses energy to pump potassium into cells and sodium out of cells. Why is ATP energy required? to change the shape of the ions to transfer glucose in the same direction as Na+ ions to pump the Na+ and K+ ions along their diffusion gradient to pump the Na+ and K+ ions against their diffusion gradient for the membrane to change shape 7. Which definition best describes a cell's metabolism? the chemical reactions that break down glucose for energy the use of ATP as an energy carrier the energy level that must be overcome for a chemical reaction to move forward the burning of fat molecules for energy the sum of all the chemical reactions occurring in an organism 8. Which reaction can provide the energy needed to run an endergonic reaction? protein synthesis photosynthesis ATP hydrolysis enzyme catalysis All answers are correct. 9. Which process(es) can directly amplify signals in a transduction pathway? activating adenylyl cyclase activating kinases activating phosphatases activating phospholipase C All answers are correct. 10. What happens when protein kinase A (PKA) phosphorylates phosphorylase kinase in the epinephrine signal transduction pathway? Phosphorylase kinase becomes deactivated, and glucose production is suppressed. Phosphorylase kinase becomes activated, and glucose production is suppressed. Phosphorylase kinase becomes deactivated, and glucose production is enhanced. Phosphorylase kinase becomes activated, and glucose production is enhanced. None of the answers are correct. 11. Which is a catabolic process? glycolysis ATP synthesis ion transport photosynthesis translation of mRNA into protein 12. Which reaction does a kinase catalyze in a signal transduction pathway? binding of a signal molecule to a receptor production of cAMP phosphorylation of a target protein All answers are correct. None of the answers are correct.
Just completed an experiment on Gluconeogenesis looking at the different precursors. I am a bit stuck on why lactate and alanine might be of different efficiency as gluconeogenic substrates.
The parasympathetic nervous division is central to maintaining homeostasis of the body. Pick one of the oxygen delivery organs and one of excretory or digestive organs.
Why is it not safe to assume that two microorganisms with the same G+C content belong to the same species? In what ways are G+C content taxonomically valuable?
If a nail were driven into a tree at a height of five feet from ground level, and thereafter the tree grew an average of two feet in height per year, approximately how high above the ground level would the nail be ten years later
Discuss the relationship between the fitness of a deleterious recessive allele, the mutation rate of the allele, and the equilibrium frequency of that allele. Be sure to address the extreme when the allele is lethal (w = 0).
Approximately half of our vitamin K is synthesized by bacteria in the colon. Based on this information, why might taking a broad spectrum antibiotic produce frequent nosebleeds.
Explain the outcome/result as Alu TE is integrated into the coding region of a gene. Illustrate the mechanism of Alu TE integration.
Use the following data to answer the questions 1 and 2. In a sample of double-stranded DNA from a particular bacterium with a circular chromosome, 43% of the nucleotide bases are Guanine (G).
In plant communities today, leaf morphology is correlated with mean annual temperature, so paleobotanists use fossil leaf morphology to estimate the mean annual temperature of paleoclimates.
How would you determine the termination codon appear in the mRNA for this gene? Write the sequence with the 5' and 3' ends of the sequence indicate clearly.
Tumor-promoting mutations are described as being either gain-of-function or loss-of function. Describe the effects of both classes of tumor-promoting mutations on the cell cycle and apoptosis.
