Question

Bacteriorhodopsin is a protein found in Halobacterium halobium that converts light energy into a transmembrane proton gradient that is used for ATP synthesis. After light is absorbed by the protein, the following initial reaction sequence occurs.

BR​→ J​→ K k1=2.0x10^ 12 s^- ­1 k2 = 3.3 x 10^ 11 s^ ­-1

a. At what time does the intermediate J​reach its maximum concentration?

b. Plot the concentration of each species versus time.
