phosphatase correct answers enzyme that removes a phosphate group from its substrate According to the information in the passage, which statement best describes the function of the MR in response to stimulation of the sympathetic nervous system? The MR: "Blood flow to the brain is regulated by changes in arterial vessel diameter in response to intravascular pressure, a process called the myogenic response (MR). The MR allows cerebral resistance vessels to achieve a state of partial constr...

Cytochrome c oxidase correct answers An enzyme responsible for electron transfer in the ETC, so inhibiting it would slow or stop the ETC. Dosing of Blast Phase Chronic Myeloid Leukemia (BP-CML) cells with cyanide would result in: correct answers Reduced intercellular ATP and apoptosis or necrosis. Cyanide binds to cytochrome c oxidase and prevents electron transfer. Inhibiting cytochrome C oxidase would decrease ATP production. thus, large dose would also cause cell death (apoptosis or ne...

Synthesis of which of the following are subject to end-product inhibition? A. AMP, GMP, and CTP only B. AMP, GMP, CTP, and UTP C. AMP and GMP only D. UTP and CTP only correct answers B. AMP, GMP, CTP, and UTP B. The diagram shows that AMP, GMP, and CTP all exert end-product (term-12feedback) inhibition, and the passage states that UTP inhibits carbamoyl phosphate synthase, a necessary enzyme in the pathway to UTP synthesis. Which of the following is the most likely value of an asth...

Magnetic fields exert forces on moving __________ particles correct answers Charged Does a photon have a positive, negative, or no charge? correct answers No charge In a chiral center, what happens if the lowest priority group is in the front of the molecule? back? correct answers Front = reverse order direction Back = normal Which direction is R chiral center? S? correct answers R = clockwise S = counterclockwise What is electron affinity? correct answers The amount of energy rele...

(*Molecular Biology) Hydrolases correct answers Enzymes that catalyze reactions between a specific substrate and water in order to break a covalent bond. (*Molecular Biology) pI (Isoelectric point) of an amino acid correct answers The pH at which an amino acid carries no electrical charge (average of the pKa's of the carboxyl and amino group) (*Genetics) Silent Mutations correct answers Mutations that do not change the amino acid sequence (*Molecular Biology) When are Amino aci...

Chemical and Physical Foundation of biological Systems Questions with Correct Answers

During Reaction 2, did the oxidation state of N change? NH3(aq) + CO2(aq) + H2O(l) → NH4+(aq) + HCO3-(aq) correct answers The part of Reaction 2 that involves nitrogen is the protonation of ammonia (NH3 + H+ →NH4+). Acid-base reactions do not involve oxidation state changes. The oxidation state of N in NH3 is -3. Each H is +1 and is balanced by the -3 of N to make a neutral compound. The oxidation state of N does not change when the N is protonated. Oxidation rules correct answers RULE...
