Penicillinase, also known as β‑lactamase, is a bacterial enzyme that hydrolyzes and inactivates the antibiotic penicillin. penicillinase follows simple michaelis–menten kinetics and reaches half its maximal rate of 6.8×10−10 µmol⋅min−1 when the penicillin concentration is 5.2×10−6 m. what would happen to the initial reaction velocity, , of penicillinase if the penicillin concentration were 10.4×10−6 m?

Explanation:

The given data is as follows.

Now, according to Michaelis-Menten kinetics,

where, S = substrate concentration = M

Now, putting the given values into the above formula as follows.

                              =

This means that would approache .

answer: enthalpy

explanation:

for a exothermic reaction, the energy is released i.e. the energy of the products is lower than the energy of the reactants.

= enthaply

= energy of products

= energy of reactants

as , thus comes out to be negative. negative value of enthalpy shows that the reaction is exothermic.

cytokinesis is the splitting of a cell membrane to form 2 identical daughter cells. it's similar to mitosis as both cells have identical copies of dna and cytokinesis is a step in the mitotic cycle.
