For her undergraduate project, jessica studied an enzyme that catalyzes the reaction a↽−−⇀b. a↽−−⇀b. for substrate a, a, she determined that km=2.5 μmkm=2.5 μm and kcat=35 min−1. jessica graduated and her project has been passed on to you. unfortunately, jessica was so busy that she sometimes forgot to record all of the details of an assay in her lab notebook. your mentor suggests that you try to back calculate some of the missing concentration values. assume that the enzyme follows michaelis–menten kinetics. in experiment a, where [a]=5 mm, she found that the initial velocity, v0, was 424 nm min−1. what was the [et] in experiment a?

Why is soap used to remove grease? a. its nonpolar end dissolves the grease. b. it makes the water bond with the grease. c. it chemically bonds with the grease. d. its polar end dissolves the grease.correct answer for apex - a, its nonpolar end dissolves the grease.

Problem page combustion of hydrocarbons such as pentane ( c5 h12 ) produces carbon dioxide, a "greenhouse gas." greenhouse gases in the earth's atmosphere can trap the sun's heat, raising the average temperature of the earth. for this reason there has been a great deal of international discussion about whether to regulate the production of carbon dioxide.(a) write a balanced chemical equation, including physical state symbols, for the combustion of liquid pentane into gaseous carbon dioxide and gaseous water. (b) suppose 0.350 kg of pentane are burned in air at a pressure of exactly 1 atm and a temperature of 20.0 degree c. calculate the volume of carbon dioxide gas that is produced.be sure your answer has the correct number of significant digits.

Read the claim. breakfast is an important meal. it jump starts the body’s process of using calories to break down food. appetite can decrease with age, but going too long without eating causes metabolism to slow down. current research shows that incorporating legumes such as lentils and chickpeas into meals boosts metabolism for twenty-four hours. who might benefit from this claim? people who have a fast metabolism stores that sell exercise equipment people who take vitamin supplements grocery stores that sell legumes
