Homework Answers
Glycolysis is a metabolic pathway where glucose is broken down to form pyruvate and ATP.
1) High levels of Amino Mono Phosphate (AMP) will speed up the glycolysis because when there are high levels of AMP in a cell it indicates that the cell was deprived of energy and it requires energy as early as possible so glycolysis occurs fast to provide energy to the cell in the form of ATP.
2) High levels of ATP will slow down the glycolysis because ATP in high levels will inhibit the rate limiting enzyme phosphofructo kinase (PFK) in the liver.
3) if there are high levels of inorganic phosphate then the process will restart

Epinephrine signaling , like that of insulin, is a multi-step
pathway with several amplification steps. Identify each of the
steps below as either allosteric activation or enzymatic.
Abbreviations: Epi (epinephrine), β2AR
(β2 adrenergic receptor), R2C2
(subunit composition of protein kinase A where R is the regulatory
subunit and C is the catalytic subunit), PDE (cyclic AMP
phosphodiesterase), PPase (phosphoprotein phosphatase).
One of these is wrong but I don't know which one you can only
choose enzymatic or allosteric as the answer...

Do expect the cell to produce more ATP from one glucose molecule or from one fatty acid molecule? Explain your answer. Indicate whether the following statements are true or false. If a statement is false, explain why it is false The proteins of the electron-transport chain remove a pair of high-energy electrons from the cofactors, NADH and FADH_2, after which the electrons move across the inner mitochondrial membrane to maintain the voltage gradient. Gluconeogenesis is a linear reaction pathway that...

15. Which statement below about the interconversion of the alpha and beta anomers of D-glucopyranose is true? The interconversion requires an enzyme called an isomerase The interconversion is spontaneous in water because the acetal functionality is labile The interconversion is spontaneous in water but is slow which is why we typically draw glucose having one anomeric form...

Metabolic Pathway Engineering Problem Set 5 Engineering a Fermentation System: Fermentation of plant matter to produce ethanol for fuel is one potential method for reducing the use of fossil fuels and thus the CO2 emissions that lead to global warming. Many microorganisms can break down cellulose then ferment the glucose to ethanol. However, many potential cellulose sources, including agricultural residues and switchgrass, also contain substantial amounts of arabinose, which is not as easily fermented. Escherichia coli is capable of fermenting...

1. What is happening in a healthy individual about an hour into a glucose tolerance test? (Note: At this early time-point, blood glucose levels are still high. Also, remember that a person who is taking a glucose tolerance test was fasting for 12 hours prior to the test!) (Select ALL that apply!) Hint: Review pages 319-325, 462-467 and 489-491 of Tymoczko 3E before attempting this question. A. Glucose is being exported by the liver B. Glucose is being taken up...

Please help with the option and explain the answer. Based on what you know about interactions between the Krüppel gene and Hunchback protein in early Drosophila embryos (see the graphs on slide 12 from lecture 12) , predict what would happen with the pattern of Krüppel expression in the embryos in which Hunchback protein is uniformly over expressed at high levels throughout the A/P axis. a) Expression pattern will remain the same b) Expression will be extended to the antherior...

The mutated allele(s) has/have lost the function of keeping brain cells healthy, and is/are therefor a dominant disease O b. Huntington is a very rare and therfor recessive. c. Huntington strikes people after reproductive age and is therefor dominant. d. The mutated allele(s) has/have gained the...

Part II – Autopsy Report • Immediate cause of death was hypoxia (suffocation or lack of oxygen). • Tissue sections from heart, lung, kidney, and liver all show massive cell death. • Staining with specific dyes showed major mitochondrial damage within the affected tissues. • Oxygen levels in the patients’ blood were approximately 110 mm Hg (normal range is 75 – 100 mm Hg). Questions 1. Recalling your knowledge of the function of organelles, what function of the cells was...
