Question 1 You are observing a reaction that is occurring fairly slowly. If you add an enzyme that can catalyze the reaction, what would you expect to observe? O It is impossible to predict. The reaction rate would increase. O The reaction rate would decrease. O The reaction rate would be unchanged.
Enzyme kinetics
In biochemistry, enzymes are proteins that act as biological catalysts. Catalysis is the addition of a catalyst to a chemical reaction to speed up the pace of the reaction. Catalysis can be categorized as either homogeneous or heterogeneous, depending on whether the catalysts are distributed in the same phase as that of the reactants. Enzymes are an essential part of the cell because, without them, many organic processes would slow down and thus will affect the processes that are important for cell survival and sustenance.
Regulation of Enzymes
A substance that acts as a catalyst to regulate the reaction rate in the living organism's metabolic pathways without itself getting altered is an enzyme. Most of the biological reactions and metabolic pathways in the living systems are carried out by enzymes. They are specific for their works and work in particular conditions. It maintains the best possible rate of reaction in the most stable state. The enzymes have distinct properties as they can proceed with the reaction in any direction, their particular binding sites, pH specificity, temperature specificity required in very few amounts.

How does an enzyme have the effect you identified in the previous question?
It decreases the energy state of the substrates and allows the reaction to proceed toward the product.
It increases the energy state of the products and allows the reaction to proceed.
It raises the activation energy and allows the substrates to be converted to products more readily.
It increases the energy state of the substrates and allows the reaction to proceed toward the product.

![The enzyme pepsin is active in your stomach (at around pH 4), where it catalyzes a reaction that breaks bonds between amino acids in
proteins. Would pepsin be expected to remain active at a neutral pH of 7? Why or why not?
You do NOT need a long essay, a few sentences is usually enough to explain why or why not.](/v2/_next/image?url=https%3A%2F%2Fcontent.bartleby.com%2Fqna-images%2Fquestion%2Fce87a6bc-4d37-43f9-a473-0b54b54b3e9d%2F64a6185d-60e8-47cd-acb8-36ad04935124%2Fpcjchkj_processed.jpeg&w=3840&q=75)
