Cells use enzymes as biological catalysts to increase or accelerate the rate of reactions, such as those in photosynthesis or glycolysis. This allows reactions to occur under conditions that sustain life.
1) Explain how an enzyme catalyzes a reaction. Include in your essay the three main steps of the cycle of enzyme-substrate interactions.
2) How is enzyme activity regulated by the cell?
Your essays should be several paragraphs in length for each question, be thoroughly paraphrased, and include appropriate in-text citations and a reference list in APA format.
