Enzymes are biological catalysts that help speed up chemical reactions in living organisms. They are highly specialized proteins with distinct structures that allow them to interact with particular substrates. Enzymes have several properties that make them important in several biological processes and thus used in healthcare sector to look for injuries and illnesses. In this article, we will discuss the types and properties of enzymes, along with their functions. But primarily, we will find the answer to this question, which is not a characteristic of enzymes.
1. What is an Enzyme?
Enzymes are proteins functioning as biological catalysts. They speed up chemical processes in living organisms. They are very efficient and operate in mild conditions. They interact with specific molecules known as substrates. It allows them to convert into various products. They are present in all living organisms, including humans, bacteria, plants, and animals.

2. What is the Role of an Enzyme?
The primary function of enzymes is to aid digestion. The process of transforming food into energy is digestion. Enzymes are present in our saliva, pancreas, intestines, and stomach. They disintegrate proteins and carbohydrates, then use the nutrients to develop and repair cells.
Additionally, they also help in breathing, building muscle, nerve functioning, and getting rid of toxins in the body.
3. What are 3 Functions of Enzymes?
After learning about which is not a characteristic of enzymes, let us discover about their 3 functions. Enzymes have an important role in many biological processes. This includes metabolism, digestion, and catalysis. Here is their brief description:
- Catalysis: To speed up chemical reactions by lowering the activation energy is their primary function. They enable reactions to proceed at a much faster rate in their presence.
- Digestion: Enzymes play a critical role in the digestion of food. Digestive enzymes break down complex macromolecules into simpler forms. The body absorbs and uses them.
- Metabolism: Enzymes are involved in the metabolism of various substances like proteins, lipids, and carbohydrates in the body. They break down these molecules into smaller components. They serve as a source of energy and in other essential cellular processes.

4. What are the Characteristics of Enzymes?
Enzymes have a number of distinguishing characteristics that allow them to act as biological catalysts. The following are the 7 properties of enzymes:
- Enzymes are highly efficient catalysts. They are capable of increasing the reaction rate by millions of times.
- The enzymes do not start a reaction. They do help in speeding it up.
- Each enzyme has an optimal temperature and pH to efficiently alter the reaction.
To control reaction rate in living organisms, enzymes can be regulated. - They can be used repeatedly.
- They are sensitive to pH levels, temperature, and related environmental conditions. They work best in a pH range of 6 and 8. An increase in temperature causes a decrease in enzyme activity.
- Enzymes recognize and bind to the substrate at a specific active site. This is when the chemical reaction takes place. Their velocity increases with an increase in substrate concentration.
- They carry out only a single type or a limited range of reaction because they are highly specific.
5. Which is not a Characteristic of Enzymes?
No chemical changes take place in an enzyme during the reaction they catalyze. They are not consumed or altered in the reaction. Therefore, a characteristic that is not associated with enzymes is that they are consumed or chemically changed during the reaction they catalyze..
6. What are the 4 Types of Enzymes?
Scientifically there are 6 types of enzymes based on the chemical process they carry out.
They are Oxidoreductases, Transferases, Hydrolases, Lyases, Isomerases, and Ligases.
But to simplify it, they are categorized in the following 4 types. So, before you know which is not a characteristic of enzymes, take a look at the types of enzymes mentioned below:
- Oxidoreductases – Oxidation is a chemical reaction in which electrons move from one form of a molecule to another. These help to catalyze oxidation reactions and reduction reactions.
- Transferases – These enzymes work to transport the functional group between the acceptor and the donor molecules. Two types of compounds are transferred to make chemical group transitions. A transaminase transfer from one amino group to another.
- Hydrolases – Hydrolases are water-soluble enzymes that aid the hydrolysis reaction. This catalysis is the hydrolysis reaction. They help a bond hydrolyze. The enzyme breaks down proteins into their peptides with the help of water.
- Lyases – If single bonds are created, they can be replaced with more than one bond. Aldolase breaks bonds naturally.

7. Is Protein and Enzyme Same?
No, proteins and enzymes are not the same. We know which is not a characteristic of enzymes, now let’s find out differences between protein and enzymes.
| Enzymes | Proteins |
| Made up of proteins. | Constituted of amino acid leftovers. |
| Only found in secondary and basic protein structures. | Present in primary, secondary, third, and fourth structures. |
| Non-covalent bonds are included in hydrogen bonds. | They have peptide bonds in their basic structure and non-covalent bonds in their higher degrees. |
| Help speed up biochemical processes. | One of the main biomacromolecules that contribute to the structure and function of the human body. |
8. Are all Enzymes a Protein?
Yes, all enzymes are proteins because a few amino acids help reduce the energy required for an enzyme. Only a few proteins have the ability to use their active sites to promote an effective reaction by binding to the substrate. As a result, while all enzymes are proteins, not all proteins are enzymes.
This description also serves as an answer to the question what kind of protein is an enzyme? Because the arrangement of amino acids is the fundamental structure of a polypeptide chain. This dictates the enzyme’s three-dimensional structure, including the active site’s shape. Did you read this interesting article on What is the Difference Between Natural and Artificial Selection?
