Given the following estimate the Vmax of the enzyme substrate / system. (Enter only a number do not enter units) We know from references that the Km of the system is 3.00 M.
Testing a substrate concentration of 3.00 M we see an enzymatic rate of 752 units per second.

the answers would be

the first one and the second one

a 20-cm-long, cylindrical graphite (pure carbon) rod is inserted into an oxidizing atmosphere at 1145 k and 1.013 x 105 pa pressure. the oxidizing process is limited by the diffu- sion of oxygen counterflow to the carbon monoxide that is formed on the cylindrical surface.
