The B1 variant of is characterized by an unusual phenotype. Patient samples contain both isoenzymes; however, lacks activity toward alpha-specific substrates. In a previous report, we analyzed the biochemical consequences of an Arg178---His substitution in the alpha-subunit, causing the B1 phenotyp...
Explain how during enzyme catalysis the transition state is stabilized providing binding energy that is used to lower the activation energy. Consider two enzymes A and B, which are not related. However, the two enzymes coincidentally share the same value for Vmax. Using this ...
The location on an enzyme where a substrate binds and is transformed to product is known as the: a. active site b. enzyme cofactor c. prosthetic group d. enzyme assay e. exositeWhen considering enzymes, what is a competitive behavior? How does it affect Vmax and ...

Calculate the maximum speed VMAX , Michael constant K M value. 1.2 Results: ( 1 ) The substrate is special Since HMT-18920 enzymes are β- glucoside enzymes, and β- glucoside enzymes are widely specific to the substrate, through enzyme hydrolysis PNPG , Onpg , PNPX , α-PNPG , pnp ...
Enzymes in the cell: what’s really going on - Brooks - 2004 () Citation Context ...e much larger than the substrate concentration, the appropriate kinetic equation is v Vmax[S]/(Km+ [Et]+[S]), where [S] is [JHf] and [Et] is the total JHE concentration in the hemolymph (Cha,...
What is an accurate way to record enzyme activity? How do enzymes lower the activation energy of chemical reactions? What are enzyme's roles in chemical reactions? What are enzymes? What role do they play in biological and chemical reactions? Do enzyme reactions ever reach vmax? Why or wh...
These enzymes act on substrates, which will help convert the enzymes into products. They also play a vital role in metabolism. Answer and Explanation: a) Isocitrate dehydrogenase: This enzyme has a vital role in Kreb's cycle. Ox...
In enzyme activity, both co-enzymes and co-factors are greatly involved. Briefly explain the difference between the two and state the functions of each. What are the structural factors that affect an enzyme's kinetics (Km/Vmax)? What factors can cause denaturing of proteins and thus inhibit ...
What does a lower Vmax mean?Enzymes:Enzymes are proteins that speed up the rate at which biological reactions take place. They do this by offering these reactions an alternative reaction mechanism that has lower activation energy. Protein Synthesis:The synthesis of proteins requires that a DNA ...
