1 BIOCHEMISTRY EXAM 2 | QUESTIONS & ANSWERS (VERIFIED) | LATEST UPDATE | GRADED A+ Covalent Catalysis Correct Answer: Active site contains a reactive group (Nucleophile) General Acid-Base Catalysis Correct Answer: Molecule (other than Water) acts as a proton donor or acceptor Metal Ion Catalysis Correct Answer: Metal ion serves as an electrophilic catalyst and stabilizes reaction intermediate Temperature Correct Answer: As temperature rises, reaction rate increases; loss of activ...

Drug Pricing (CHPA)The US is the only developed nation that lets ____ set their own prices - correct answer drugmakers in Europe, Canada and Australia they see the market for cures as ____ ____ and set the prices through a ___ process - correct answer essentially uncompetitive bureaucratic how do drug companies set their American prices? They set their prices regardless of what? - correct answer they don't focus on the cost of making the pills, they look at what their competitors charge...

Enzymes - ANSWER--Increase reaction rate (Vo) - "velocity"; M/min or mol/min -Are not used up in reaction Enzyme functions under mild conditions - ANSWER-- temperature - pH - pressure Structure of Enzymes - ANSWER-- vast majority are proteins - many need a non-amino acid component to be functional Function of Enzymes - ANSWER-Enzymes increase velocity by which product is formed over time Enzyme kinetics - ANSWER-- Helps understand and predict enzymatic reactions and factors aff...

enzyme concentration correct answers the more enzyme present, the faster substrate reacts pH correct answers enzymes have optimum pHs above and below which the rate decreases Pepsin is correct answers a proteolytic enzyme found in the Stomach Chymotrypsin is a correct answers proteolytic enzyme found in the intestine Temperature correct answers enzymes have an optimum temperature, above which they begin to denature An enzyme, tyrosinase, is key in the production of melanin (the mo...

1. Competitive inhibitor - Ans a. Binds to the active site and prevents the substrate from binding b. -Adding more substrate would increase the rate of the reaction (can outcompete the inhibitor) c. -usually transition state analogs 2. Noncompetitive inhibitor - AnsSpecial case of the mixed inhibitor where it can allosterically bind to both the enzyme or enzyme-substrate complex with equal affinity -increasing substrate concentrations will not be able to affect rate 3. Uncompetitive in...

A complex organic molecule that is necessary for enzyme function but is NOT permanently associated with the enzyme is a: A) prosthetic group. B) cofactor. C) holofactor. D) coenzyme. E) metal ion. - D) coenzyme. A double-reciprocal plot of 1/V0 versus 1/[S] for an enzyme in the presence of increasing concentrations of an uncompetitive inhibitor will have lines corresponding to the different inhibitor concentrations that are BEST described by which statement? A) The lines will intersect...

A+ GRADE. Which level of protein structure is disrupted through the hydrolysis of peptide bonds? Quaternary Tertiary Primary Secondary - Correct Answer -Primary The primary structure of a protein is the sequence of amino acids held together by peptide bonds. Peptide bonds are formed by dehydration reactions and disrupted by hydrolysis. A mutation in the beta-hemoglobin gene, which results in the replacement of the amino acid glutamate in position 6 with the amino acid valine, leads to the...

Biochem Module 3 Advanced Test 2024.True or False: The amino acids serine and methionine both contain sulfur atoms. - ANSWER false True or False. The side chain of proline is bonded to the backbone nitrogen atom. - ANSWER true True or False: The name of the molecule that binds to an enzyme is called the apoenzyme. - ANSWER false True or False: An inhibitor that binds at the active site is an uncompetitive inhibitor. - ANSWER false Which amino acids differ by only one atom? Ser and ...
