- MATHEMATICAL You do an enzyme kinetic experiment and calculate a Vmax of 100 mol of product per minute. If each assay used 0.1 mL of an enzyme solution that had a concentration of 0.2 mg/mL, what would be the turnover number if the enzyme had a molecular weight of 128,000 g/mol?MATHEMATICAL For the Vmax obtained in Question 26, calculate the turnover number (catalytic rate constant) assuming that 131024mol of enzyme were used.MATHEMATICAL Which is more favorable energetically, the oxidation of succinate to fumarate by NAD+ or by FAD? Give the reason for your answer.
- If an enzyme catalyzed reaction has a KM of 5mM and a Vmax of 60 nm/sec, the substrate concentration at 30 nM/sec is? Thank you.Enzyme Kinetics question Enzyme used is 10uL of a 10 ng/uL solution to a reaction mix in a final volume of 2.0 mL. (Enzyme used is 20kDa monomeric enzyme if matters) Based off lineweaver burk where 300 uM of inhibitor is used noninhibited formula is y= 4x + 0.1 (x axis is 1/S 1/mM) (y axis is 1/Vo sec/mM) inhibited formula is y = 4x + 1 I found Km as 1 mM for inhibited Vmax as 1mM/sec for inhibited How would I find Kcat? How would I find Ki?The purpose of the progress curve is to determine if an enzymatic reaction rate remains constant for given concentrations of enzyme and substrate, for a given assay time (20 min). How long did the rate of reaction of WGAP remain constant in your experiments? How do you know? What would cause the reaction rate to not be constant and plateau after some time?
- Question- How many RefSeq nucleotide sequence records are there in GenBank for alcohol dehydrogenase in corn? Do they all code for alcohol dehydrogenase?Question:- The enzyme aromatase is found in the cytoplasm of some cells and converts testosterone to estrogen. You decide to test aromatase from a particular cell, and oops, your lab partner admits he drastically increased the pH in all the test tubes. Which of the following is a likely result? a. The enzyme will be denatured and the substrate will not bind to the active site. b. The enzyme will convert testosterone to estrogen at a faster rate. c. The mistake will have no effect on the experiment, because enzymes are not sensitive to pH. d. The free energy will be lowered and the reaction will not proceed spontaneously.THOUGHT QUESTION Imagine we identify a gene that is directly responsible for the effects of vasopressin on male mammals, including humans-we will call it trust1-that leads to the production of a vasopressin receptor in the brain, which we will call TRUST1. There are different versions of trust1, all of which lead to different levels of the behavior associated with this neuropeptide on male behavior. Give some examples where it would be a good idea to know a particular males genotype-that is, which of the trust1 genes he has. Give an example of when you think science has gone too far and this information should not be known.
