Important biological reactions catalyzed by enzymes: Oxidase, reductase = oxidation, reduction reaction, Dehydrogenase = removes hydrogen (oxidation), can also work in reverse (reduction), Kinase (adds), phosphatase (removes) phosphate groups, Protease, amylase, lipase = hydrolyzes proteins, carbohydrates, fats, DNAse, RNAse, nuclease = hydrolyzes phosphodiester bonds in nucleic acids, Polymerase = makes DNA/RNA/protein (polymers of nucleic acids/amino acids), Transcriptase = transcribes RNA from DNA template (reverse transcriptase makes DNA from RNA template), Ligase = forms bonds between 2 strands of DNA/RNA, Enzymes decrease the activation energy (E. Enzymes increase the rate of a reaction by decreasing the activation energy. 'months' : 'month' }} The bile duct releases pancreatic juice and bile into the small intestine. {{ nextFTS.remaining.days }} RNase II is a monomer of 72 kDa and 644 amino acids (aa), encoded by the rnb gene from E. coli.The rnb gene is transcribed by two promotors, P1 and P2, and terminates in a Rho-independent terminator 10 nts downstream of the rnb stop codon. as Structure determines function. Premature infants lack vitamin K because they haven't had time to acquire the gut bacteria that makes vitamin K), Water soluble vitamins: anything that's not fat soluble. Small intestine. {{ nextFTS.remaining.days > 1 ? An inhibitor binds to an allosteric site on the enzyme to deactivate it. Competitive inhibition increases Km (the amount of substrate needed to achieve maximum rate of catalysis). When solving a problem that includes a table, which rule helps you identify the biological ideas that you'll need to reference in order to solve the problem? Induced fit model: flexible active site. Enzyme C is more active at lower pH values. Enzyme B has more enzyme activity than Enzyme A at a pH of 6. Endonuclease: endonuclease is an enzyme that cuts DNA at or near specific recognition nucleotide sequences known as restriction sites. Primary: this is the sequence of the protein or RNA chain. {{ nextFTS.remaining.months > 1 ? Different bonds/interactions contribute to the stability of each level of protein structure. To learn more about this decision, please visit our helpdesk article at the link below. Enzymes affect the kinetics of a reaction, but not the thermodynamics. An identification of the copyright claimed to have been infringed; accessory digestive organ: an organ that helps primary digestive organs like stomach and intestine in the digestion. You can overcome competitive inhibition by providing more substrate. The #1 social media platform for MCAT advice.
