Question: Effect of enzymes on chemical reactions certain proteins, known as enzymes, serve as catalysts for chemical reactions in living things. In 1913 leonor michaelis and l. M. Menten discovered the following formula giving the initial speed v (in moles/liter/second) at which the reaction begins in terms of the amount of substrate x (the substance that is being acted upon, measured in moles/liter):
V = ax
x + b
Where a and b are positive constants.
A. Find the horizontal asymptote of v.
B. What does the result of part (a) tell you about the initial speed at which the reaction begins, if the amount of substrate is very large?
