Acs Exam Questions And Answers Latest Update (2024 / 2024) (Verified Answers)

helicase/DNAB {Ans: protein that catalyzes the ATP-dependent unwinding of DNA double helices (DnaB is the helicase in E. coli)}when in presence of carbon, hydrogen (will/will not) make an H-bond with carbon {Ans: will not (there isn't enough electronegativity to have a net-dipole moment)}Protein % composition from greatest to least by: {Ans: HDL>LDL>IDL>VLDL>Chylomicrons}quarternary structure {Ans: - not all proteins have - highest structure a protein can have proteins that have multiple subunits which makes up the whole protein such as hemoglobin}competitive inhibition {Ans: - inhibitor binds in active site - ES or EI only, as a competitive inhibitor in the active site means both cannot be bound at once (therefore NO ESI) - Vmax unchanged: can overwhelm inhibitor with excess substrate -Km increased: need more substrate to reach ½ Vmax There is lesser formation of E-S complex. High [S] solves problem.}identification of reducing sugars {Ans: contain an aldehyde group or have an anomeric carbon that does not participate in glycosidic bond}
