Which statement regarding regulation of glycolysis and gluconeogenesis is FALSE? A) Phosphofructokinase-1 and fructose 1,6-bisphosphatase are PRevented from forming a futile cycle by reversible covalent modificatio...

What is the difference between the net number of ATP generated by glycolysis from glucose produced by the glycogen phosphorylase enzyme reaction as compared to glucose obtained from the diet? correct answers One less net ATP is generated in glycolysis from dietary glucose as compared to glucose from glycogen. Part 1: Glycogen metabolism is regulated by both allosteric control and covalent modification. Circle the best underlined words describing glycogen regulation and record the number. corr...

UNE Medical Biochemistry Midterm Review Already Graded A A family presents for genetic counseling. The couple has two female children who are alive and well; however, their infant son recently died in the nursery with severe hemolysis (lysis of red blood cells) and jaundice. The wife recalls she lost a brother in infancy with severe hemolysis, induced after a viral infection. The physician suspects a glucose-6-phosphate dehydrogenase deficiency, this would result in a deficiency in which of the...

Complex IV (Cyt c oxidase) c.) Complex V (ATP synthase) d.) complex II (Succinate-Q reductase) - correct answer. Complex II (succinate-Q reductase) (D) Which of the following would be consistent with an exergonic reaction? a.) ∆S would be negative b.) ∆G would b...

Biochemistry Test 1 Questions and Answers Graded A+ What is the role of allosteric sites in enzyme regulation? Allosteric sites are regions where molecules can bind and influence enzyme activity by changing its shape. How do competitive inhibitors affect enzyme function? Competitive inhibitors compete with substrates for binding at the active site, reducing enzyme activity. What determines the tertiary structure of a protein? The tertiary structure is determined by interactio...

BI234 CH - MICROBIAL METABOLISM EXAM QUESTIONS AND ANSWERS WITH COMPLETE SOLUTIONS What role do enzymes play in metabolic pathways? Enzymes control the chemical reactions in metabolic pathways. They are necessary for metabolism to occur. How is the action of a competitive inhibitor different from that of an allosteric inhibitor? -Competitive inhibitors have a shape that is similar to the substrate of the enzyme and bind to the active site of the enzyme - these inhibitors compete for the ac...
