Find kcat for a reaction in which Vmax is 4 x 10-4 mol-min-1 and the reaction mixture contains one microgram of enzyme (the molecular weight of the enzyme is 200,000 Da). Enzyme has one active site. (Hint: Find the number of moles of active site first)

The  grandmother cell  is a hypothetical  neuronthat represents a complex but specific concept or object.[1]  it activates when a person "sees, hears, or otherwise sensibly discriminates"[2]  a specific entity, such as his or her grandmother. the term was in use at least as early as 1966 amongst staff and students in the department of experimental psychology, university of cambridge, england. a similar concept, that of the  gnostic neuron, was proposed two years later

Okay well gravitational energy is matter forced by gravity making energy though the kinetic energy then the electric energy produces electricity from the kinetic energy and the kinetic energy gets its energy from the gravitational energy. was that the answer you wanted or something else?  

Hcn is the correct answer leave a good rate and .
