Question

question 1-2
what will happen to the rate of enzyme activity if substrate is continuously added to a fixed amount of enzyme?
initially decrease, then increase
initially increase, then remain constant
initially decrease, then remain constant
initially increase, then decrease

Explanation:

Enzyme - substrate reactions follow Michaelis - Menten kinetics. Initially, with more substrate available, more enzyme - substrate complexes can form, increasing the reaction rate. But once all enzyme active sites are saturated, adding more substrate has no effect as the enzyme is already working at its maximum capacity.

Answer:

Initially increase, then remain constant
