3. Not Changed
Explanation:
I got them all correct.
The Catalysts (also called enzymes) are those chemical substances having the ability to increases reaction rates, and they do so by lowering the activation energy that is required to initiate the chemical reaction.
Characteristics of a Catalyst:
- Catalysts are generally specific in nature for a particular chemical reaction.
- They have the ability to alter the rate of a chemical reaction.
- They are required to lower the activation energy of both forward and reverse reaction.
- They are not consumed in the reaction and eventually can be reused in the subsequent reaction.
- They are required in very small amounts or quantities.
- Temperature, pH, and inhibitors can affect the efficiency by which a catalyst act.
An inhibitor is a substance that can reduce or entirely inhibit a chemical reaction or the activity of another substance (such as a catalyst or an enzyme). There are three kinds of reversible inhibitors: competitive, noncompetitive/mixed, and uncompetitive inhibitors.
- Competitive inhibitor: It resembles the normal substrate that binds to the catalyst or an enzyme at its active site, and prevents the substrate from binding.
- Noncompetitive inhibitor: It binds to an allosteric site resulting in decreased efficacy of the enzyme.
- Mixed inhibitor: This type of inhibitor can bind to the enzyme whether or not the enzyme has already bound the substrate.
