The covalent catalytic mechanism of an enzyme depends on nucleophilic attack by an active site cys whose pk is 8. a mutation in a nearby residue alters the microenvironment so that this pk increases to 10. would the mutation cause the reaction rate to increase or decrease?

i guess that visual aids present persuasive examples to what you are presenting, some factors would be theme (does it fit with the color, information, what you are presenting), size (can you see it, is it a big enough span of data/information), and overall look of the visual aid.

hope this : )

it is a negative acceleration

gravitational energy

electrical energy

kinetic energy

ligh energy
