Antibiotic-resistant bacteria have an enzyme, penicillinase, that catalyzes the decomposition of the antibiotic. the molecular mass of penicillinase is 31200 g/mol. the turnover number of the enzyme at 28 °c is 2.00 × 103 s–1. if 4.10 μg of penicillinase catalyzes the destruction of 2.83 mg of amoxicillin, an antibiotic with a molecular mass of 364 g/mol, in 29.6 seconds at 28 °c, how many active sites does the enzyme have? assume that the enzyme is fully saturated under the conditions described above.

Imagine that a new planet is discovered with two moons of equal mass: moon a and moon b. the mass of the new planet is greater than the combined mass of its moons. moon a is farther away from the new planet than moon b. what is the planet's gravitational pull on moon a compared to the planet's gravitational pull on moon b? the planet's gravity repels moon a with a greater force than it repels moon b, which is why moon a is farther away. the gravitational pull on moon b is greater than on moon a because moon b is closer to the new planet than moon a. the gravitational pull on moon b is greater than on moon a because moon b is farther away from the new planet than moon a. the gravitational pull on moon a is the same as the gravitational pull on moon b because distance does not affect the planet's gravity.
