Enzymes play an important role in various actions and reactions of the body. However, they do not always act independently and often depend on other body components, such as substrates, which are molecules that these enzyme molecules can latch on to and use as catalysts to speed up their actions. Typically, in chemistry, a substrate is a chemical species that reacts or combines with a reagent, acting as a catalyst, facilitating the main reaction and playing an important part in the production of the desired product.
It is an important topic in biology and biochemistry and plays a vital role in various life processes. Essentially, in biochemistry, the substrate, also known as an enzyme-substrate, is a substance upon which an enzyme acts, producing a product. Substrate property is the set of properties that a substrate has and how they act and carry out their functions through reactions.
Enzymes: Their actions and their relation to substrate
The simplest way to describe enzymes would be to say that they are proteins that combine with other body components to produce various important products or carry out various important life processes. It is an important area of study in biochemistry and medicine. Enzymes act as biocatalysts, that is, biological catalysts. Then, this is where substrates come in, as the molecules upon which enzymes act are known as substrates. These substrates are converted into various desired molecules known as products in terms of biology, the substrate in the catalyzation of the chemical reactions by the enzymes. Thus, this would be the correct answer if asked, “what does a substrate do to an enzyme?”
Naturally, without any external intervention, metabolic and biological processes are not fast enough to sustain life. This is why enzymes are important, as they act as catalysts and speed up these processes fast enough to sustain life properly. A linked series of chemical reactions, which occur inside a cell and are better known as a metabolic pathway, greatly depend on enzymes. The importance of enzymes can be understood because they are known to act as catalysts in more than 5000 different types of biological processes and reactions.
What does a substrate do, exactly?
Substrates essentially act as a site for the action of an enzyme. When there is a solitary substrate, an enzyme-substrate complex bond is formed by bonding the enzyme reaction site and the substrate. The substrate is then modified into one and, in some cases, multiple products, which were desired. After this, these products are released from the enzyme active site. This process is repeated as it is now free to receive another substrate molecule upon the release of the products from this active site.
However, when there is more than one substrate, the substrate molecules can bond together like a chain and then react together and be turned into products. Sometimes, an enzyme may react with a substrate and produce a product that has a particular colour. This kind of substrate is known as a “chromogenic” substrate. In many cases, fluorescent products are also produced when enzymes react on certain substrates, and such substrates are known as “fluorogenic” substrates.
How do substrates bind with enzymes?
Studies have shown that substrates bind with enzymes similarly to how ligands bind themselves to proteins. However, a major point of difference is that, before they bind to the enzymes, they undergo a vital chemical process in which they are converted to products. Only then can they bind with the enzymes.
The substrate interacts with the amino acids at the binding sites and undergoes a chemical process induced by enzymes and thus happens at the binding site. The binding site has previously been referred to as the active site of the enzymes, and this is where amino acids are contained, and they help the substrates be converted to products.
The working mechanism of an enzyme in a substrate
Right at the beginning, the enzyme binds itself to the substrate molecule, and its original shape gets distorted. This distortion in shape is highly essential as this activates the substrate molecule and also brings down the total activation energy required by the substrate molecule and thus greatly facilitating the binding of the substrate molecule and the enzyme. It has a positive impact on the substrate molecule turning into the product. The number of activated molecules keeps increasing, and so does the conversion rate to the product.
Conclusion
Thus, the substrate property of enzymes is highly important in the proper functioning of the body as they aid in important biological processes and help the enzymes, which are the biological catalysts. Substrate property is highly important and will help the reader understand the working of enzymes and various vital metabolic processes of the human body.
