A plant that has seed very rich in an oil that can be directly used as a biofuel to power vehicles has been discovered. the plant is able to grow on a marginal farm land and thus fuel oil production would not compete with food production. unfortunately the plant only […]

The KM of a Michaelis-Menten enzyme for a substrate is 1.0 x 10-4 M. At a substrate concentration of 0.2 M, νo = 43 μM x min-1 for a certain enzyme concentration. However, with a substrate concentration of 0.02 M, νo has the same value. (A) Using numerical calculations show […]
