enzyme has Vmax of 1500 mmol * min-1 * L-1 and Km of 0.50 mM. What is Ki for a competitive inhibitor of this enzyme if 0.10 mM inhibitor cuts the rate of catalysis 50% in the presence of 2.0 mM substrate?

Consider this initial-rate data at a certain temperature for the reaction described by

If e is the symbol for an element, which two of the following symbols represent isotopes of the same element? 1. e2. e3. ea.1 and 2c.1 and 4b.3 and 4d.2 and 3

Afusion reaction takes place between carbon and another element. neutrons are released, and a different element is formed. the different element is a) lighter than helium.b)heavier than helium.c)the same weight as helium.d)dependent on the element that reacted with carbon.
