For her undergraduate project, jessica studied an enzyme that catalyzes the reaction a = b. for substrate a, she determined that km = 4.5 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. a.) in one experiment where [a] = 5 mm, she found that the initial velocity, v0 was 334 nm min–1. what was the [et] she used in this experiment?

answer: your mm

explanation:

hydrocarbons are organic compounds that contain only hydrogens and carbons. they can be saturated (those which contain only carbon-carbon single bonds) or unsaturated (those which contain carbon-carbon double or triple bonds) in nature. hydrocarbons can undergo several reactions like substitution, elimination etc.  

on substituting one or more hydrogen atoms in hydrocarbon it results in the formation of haloalkane. as the halogen atoms are large compared to the carbon and hydrogen atoms, due to which the molecular weight increases and the bond become polar because of presence electronegative halogen atom and results in the increase in boiling point of the haloalkane.

thus, the correct option is (b) that is the boiling point of the new compound increases on substituting a hydrogen atom with a halogen in a hydrocarbon.

c. orbital shape i hope this is correct
