What is an emzyme.

Enzymes are typically proteins and each is composed of a specific sequence of amino acids. Hydrogen bonds form between specific amino acids and help create the 3-dimensional shape that is unique to each enzyme. The shape of an enzyme, particularly its active site, dictates catalytic specificity of a particular enzyme.transferase, any one of a class of more than 450 enzymes that catalyze the transfer of various chemical groups (other than hydrogen) from one compound to another. Transaminases, for example, catalyze the transfer of an amino group (―NH 2) from an amino acid to an a-keto acid.Phosphate, methyl (―CH 3), and sulfur-containing groups …Importance of Enzymes. Enzymes are involved in most of the biochemical reactions that take place in organisms. About 4,000 such reactions are known to be catalyzed by enzymes, but the number may be even higher. Enzymes allow reactions to occur at the rate necessary for life. In animals, an important function of enzymes is to help digest food.Enzymes. Enzymes are nitrogenous organic molecules produced by living organisms such as plants and animals. A long chain of one or more amino acids is connected together using amide or peptide bonds to make them. They are high-molecular-mass proteins that catalyse natural processes in the bodies of animals and plants.

Enzymes are a class of biomolecules responsible for catalyzing chemical reactions in cells. Enzymes make life possible, as they allow for many of the most important biochemical changes in cells. Indeed, without enzymes, crucial processes such as cellular respiration, photosynthesis, and protein synthesis would not occur.

For every enzyme, there is an optimum pH value, at which the specific enzyme functions most actively. Any change in this pH significantly affects the enzyme activity and/or the rate of reaction. To know more about the relation between pH and enzymes, and/or the effect of pH on enzymes, go through this write-up.

May 28, 2020 · General Properties Of Enzymes. Enzymes initiate and accelerate the rate of biochemical reaction. The activity of enzymes depends upon the acidity of medium (pH specific). Each catalyst is most active at a specific pH. For example, pH 2 for pepsin, pH 8.5 for trypsin. Most intracellular enzymes function at near neutral pH. Enzymes accelerate reactions also by altering the conformation of their substrates to approach that of the transition state. The simplest model of enzyme-substrate interaction is the lock-and-key model, in which the substrate fits precisely into the active site (Figure 2.24).Enzymes are generally globular proteins, acting alone or in larger complexes.
