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?

Observations show that interstellar clouds can have almost any shape and

What are some properties of transverse waves?

An air-filled capacitor is formed from two long conducting cylindrical shells that are coaxial and have radii of 26 mm and 103 mm. the electric potential of the inner conductor with respect to the outer conductor is - 700 v (k = 1/4πε 0 = 8.99 × 109 n · m2/c2) the energy stored in a 1.0-m length of this capacitor is closest to
