In the reaction provided below, glucose-6-phosphate accumulates in the cell and binds to hexokinase at a site that is distinct from the active site. This prevents hexokinase from binding to its substrate. What type of inhibition is occurring in this example? - correct answer Non competitive
In Chronic Mylogenous Leukemia (CML), a mutation results in the production of BCR-ABL, an enzyme that speeds up cell division using ATP as a substrate. The drug Gleevec, impairs the activity of the enzyme. Using the illustrations of the enzyme below, what best describes how the drug exerts its effect? - correct answer Gleevec is a competitive inhibitor and prevents ATP from binding with the active site of the enzyme.
What happens to the enzyme at the end of the cycle? - correct answer The enzyme is used again. The enzyme will bind to a substrate.
Inhibitors that have a similar structure to a substrate of an enzyme are most likely to bind to the enzyme's ____________ and be a ____________ inhibitor. - correct answer Active site, competitive
You are in charge of designing a drug that inhibits the activity of a specific enzyme. An important criteria for the drug selection is to ensure that the drug directly competes with the original substrate by binding to the active site of the
enzyme. Which of the following kind of inhibitor would be an ideal choice? - correct answer Competitive site
What process takes place in the inner membrane of the mitochondria? - correct answer Electron Transport Chain Where is energy stored in an ATP molecule? - correct answer In bonds between phosphate groups
Which of the following processes does NOT take place in the mitochondria of a cell? - correct answer Conversion of pyruvate to lactic acid
Carbohydrates, fatty acids, and amino acids can all enter the citric acid cycle through which molecule? - correct answer Acetyl-CoA
During strenuous exercise, oxygen is scarce in skeletal muscle fibers. How many net ATP molecules are produced during glycolysis? - correct answer A defect occurs that prevents pyruvate from converting to lactate under anaerobic conditions. What is a possible consequence? - correct answer Glycolysis stops because NAD+ levels are low
How many rounds of beta oxidation are needed to break down the pictured fatty acid? - correct answer 8
The fatty acid CH3(CH2)4CH=CH(CH2)4COOH has been through one round of beta oxidation. What is the structural formula for the remaining fatty acid? - correct answer 'CH3(CH2)4CH=CH(CH2)2COOH'
In the absence of oxygen in the exercising muscle, why does the amount of lactate in the blood change? - correct answer The amount of lactate increases because lactate produced in muscles anaerobically must travel to the liver.
How does the change in lactate concentration affect the pH of the blood in muscle tissue? - correct answer An increase in lactate concentration causes the pH of the blood in muscle tissue to decrease.
