The kinetics analyses of an enzyme are measured as a function of substrate concentration in the presence and in the absence of 2mM inhibitor.
[S] (μM): 3, 5, 10, 30, 90
Velocity (μmol/min): With No Inhibitor: 10.4, 14.5, 22.5, 33.8, 40.5
Velocity (μmol/min) With Inhibitor: 4.1, 6.4, 11.3, 22.6, 33.8
(a) What are the values of Vmax and Km in the absence of inhibitor? In its presence?

The earth consists of a variety of different organisms. despite their diversity, however, some similarities on the structural and metabolic levels may be seen. these similarities can be attributed to a. similarities among organisms in their proteins and nucleic acids. b. the ability of organisms to readily adapt to sudden environmental changes. c. similarities in organisms' habitats and niches. d. the ability of all organisms to interbreed and produce new species.

Acar company is testing seatbelts using crash test dummies. the company finds that when cars come to a sudden stop, the crash test dummies' bodies continue to move forward. the seat belt keeps the crash test dummies from hitting the back of the seat in front of them. why do the crash test dummies' bodies continue to move forward even though the car stopped? a. the friction opposing their bodies' movement keeps them in motion. b. the inertia of their bodies keeps them in motion. c. the forward acceleration of the car keeps them in motion. d. the gravity pulling on the car keeps them in motion.

Ecologist have observed a sharp increase of sulfur dioxide in the air . what might be a possible consequence of excessive sulfur dioxide in the air ? a. acid rain b. ozone layer depletion c. ozone layer hole d. increase in sea levels
