Pyruvate dehydrogenase (PDH) activity is controlled by phosphorylation such that PDH activity is increased (R state) when it is dephosphorylated. What enzyme decreases PDH activity (T state)? -Correct Answer -PDH kinase malate dehydrogenase = citrate cycle enzyme -Correct Answer -Biochemical reaction = dehydrogenation reaction Succinyl- CoA synthetase = citrate cycle enzyme -Correct Answer -Biochemical reaction= Substrate level phosphorylation reaction succinate dehydrogenase = citrate ...

Acetylcholinesterase is an important enzyme in the nervous system. Acetylcholinesterase activity is blocked by the nerve agent sarin gas, which forms a covalent bond with a Ser in the active site of the enzyme. Sarin gas is a(n) irreversible inhibitor. competitive inhibitor. reversible inhibitor. allosteric effector. -Correct Answer -irreversible inhibitor. "forms a covalent bond with a Ser" An inhibitor that binds only to the ES complex and not free enzyme is known as a(n)...

Which state of glycogen phosphorylase gives the enzyme its highest activity? -Correct Answer -phosphorylated glycogen phosphorylase Observe the ribbon structure of pepsin. To do this, click the green-outlined box at the bottom of the player. Green x's will appear over your selection. Then go to the dropdown menu and on the "Display" line, click the "Toggle Ribbon for selection" icon. Then click the "Toggle CPK for selection" icon to remove the space-filling display. To re...

Consider the following interaction between a protein and its : [P] + [L] [PL]. If [L] = 5 mM, [P] = 3 mM, and [PL] = 2 mM, what is the dissociation constant? -Correct Answer -7.5 mM Which of the TWO following statements about x-ray crystallography are true? -Correct Answer -Only crystallized proteins can be analyzed. The x-ray beam is scattered by the protein sample. A purified protein shows a single band on a native polyacrylamide gel. The band runs toward the cathode at pH 7. The fig...

After centrifugation, there is a 10% decrease in activity and a 75% decrease in total protein. What is purification of the target protein? -Correct Answer -3.6-Fold Below is a fractional saturation curve for O2 binding to adult hemoglobin. Assume that curve Y represents a system at pH 7.4 and with a normal physiological level of 2,3-BPG. Curve X represents a system that -Correct Answer -has a higher pH with a normal physiological level of 2,3-BPG. Consider the following interaction between...

Fatty acids are amphipathic, meaning that within the molecular structure, A. One end is polar and the other is non-polar B. Both ends interact with water, they are both hydrophilic C. Both ends repel from water, they are both hydrophobic D. One end is negatively charged and the other end is positively charged A. One end is polar and the other is non-polar High-throughout DNA sequencing and bioinformatics have greatly facilitated our ability to study evolutionary history. Which of the...

Select the TWO true statements below describing the standard free energy change (delta G) and the equilibrium constant (Keq). The equilibrium constant is equal to ratio of the concentration of reactants over products at equilibrium. If the value of the equilibrium constant is known, the value for the standard free energy change can be determined. The value for the standard free energy change is constant for a given reaction. The standard free energy change is a function of enzyme c...
