When a reactant binds to an enzyme it binds in a region termed the?
The location within the enzyme where the substrate binds is called the enzyme’s active site. The active site is where the “action” happens.
What is the name of region where a reactant binds to an enzyme?
The part of the enzyme where the substrate binds is called the active site (since that’s where the catalytic “action” happens).
What is a reactant to which an enzyme binds?
The chemical reactants to which an enzyme binds are called the enzyme’s substrates. There may be one or more substrates, depending on the particular chemical reaction. In some reactions, a single reactant substrate is broken down into multiple products.
What happens to enzyme and substrate during a chemical reaction?
Explanation: a) The substrate fits into the active site of an enzyme during a chemical reaction. After changes in the substrate are made the substrate are made, the substrate moves and another substrate fits into the active site. The shape of the active site remains unchanged.
How does an enzyme alter rate of chemical reaction?
Enzymes are biological catalysts. Catalysts lower the activation energy for reactions. The lower the activation energy for a reaction, the faster the rate. Thus enzymes speed up reactions by lowering activation energy.
What kind of reaction is driven by the enzyme?
Enzymes allow many chemical reactions to occur within the homeostasis constraints of a living system. Enzymes function as organic catalysts. A catalyst is a chemical involved in, but not changed by, a chemical reaction. Many enzymes function by lowering the activation energy of reactions.
Which enzyme is the builder?
DNA Polymerase. What is the “builder enzyme” ; replicates DNA molecules to make new strands of DNA? Primase.
What is the chemical reaction that is catalyzed by the enzyme?
Enzyme catalysisAn enzyme catalyzes a biochemical reaction by binding a substrate at the active site. After the reaction has proceeded, the products are released and the enzyme can catalyze further reactions.
What are two ways a catalyst affects a chemical reaction?
The two main ways catalysts affect chemical reactions are by creating a way to lower activation energy or by changing how the reaction happens.
What are four factors that affect the rate of a chemical reaction?
The factors that affect reaction rates are:
- surface area of a solid reactant.
- concentration or pressure of a reactant.
- nature of the reactants.
- presence/absence of a catalyst.
How does an enzyme speed up a chemical reaction quizlet?
How do enzymes speed up chemical reactions? Enzymes speed up reactions by lowering activation energy, the lower the activation energy for a reaction, the faster the rate.
