Verified step by step guidance

Understand that the rate of a biochemical reaction can be influenced by several factors, including substrate concentration, enzyme concentration, and temperature.

Recall that increasing the concentration of substrates ([substrate]) generally increases the reaction rate because more substrate molecules are available to interact with enzyme active sites.

Recognize that increasing the concentration of enzymes ([enzyme]) can also increase the reaction rate, as more enzyme molecules are available to catalyze the reaction.

Consider the effect of temperature on reaction rate. Slightly increasing the temperature can increase the kinetic energy of molecules, leading to more frequent and effective collisions between enzyme and substrate, thus increasing the reaction rate.

Identify that increasing the concentration of products ([product]) is not a method to increase the reaction rate. In fact, it can lead to product inhibition, where the accumulation of products can slow down or reverse the reaction.
