I am a bit confused about this PPT slide explanation. Why would a high energy transition state be favored when it requires more activation energy in an enzyme-substrate binding scenario?
1. Provide the best coenzyme(s) for each step shown below. Give a 1–2 sentence rationale for your choice. 2. Reaction (C) can require multiple coenzymes, or the enzyme may only require one. Briefly describe how the reaction that uses only one coenzyme works. Be specific about the mechanism.
Give detailed Solution with explanation needed...give correct answer please
What is the function of Histidine as part of the catalytic triad? O The alcohol group of histidine makes a nucleophilic attack on a peptide C=O bond. O The imidazole group acts as a general base and extracts a proton from serine activating it to attack the substrate O The imidazole group acts as a general base and extracts a proton from aspartate activating it to attack the substrate O The imidazole group acts as a general base and extracts a proton from aspartate allowing it to activate serine by transferring a proton
To investigate the effects of a newly discovered inhibitor and enzymology list obtained the results showed in the figure below. Which statement best describes the binding of its inhibitor on the enzyme? ~y=0.768r+4.7425 3-0.568x+46576 19 . . . . ● x X The inhibitor binds at the active site. The inhibitor binds away from the active site, but after substrate binding. The inhibitor binds away from the active site before or after substrate binding. The inhibitor binds close to the active site, but after substrate binding. The inhibitor binds close to the active site, but prior to substrate binding. red by a strain

1967, Rabin demonstrated that a single substrate reaction catalised by an enzyme that has a single binding site for the substrate, can show sigmoidal kinetics. Discuss this scenario so that it is clear why a plot of Vo versus [SJ at fixed total enzyme concentration will be sigmoidal.
