Simple definition of enzyme
Webb16 aug. 2024 · Enzymes are the biological macromolecules which speed up the rate of biochemical reactions without undergoing any change. They are also called as biological catalysts. An enzyme is a highly selective catalyst that greatly accelerates both the rate and specificity of metabolic reactions. Properties of Enzymes. WebbEnzymes are biological catalysts. Just like other catalysts, they reduce activation energy, allowing reactions to proceed in a desired direction. Because their activity is dependent on the folding of a protein, they are usually sensitive to the temperature, pH, and salt concentration of the environment they work in.

Webb7 nov. 2024 · An enzyme is a macromolecule that catalyzes a chemical reaction. In other words, it makes an unfavorable reaction able to occur. Enzymes are built from smaller molecules to make an active subunit. One of the most important parts of an enzyme is the coenzyme. Key Takeaways: Coenzymes WebbOn the basis of chemical nature, enzymes are also 2 types: (i) Simple enzymes: They consist of only proteins, e.g. urease, lysozyme, pepsin, trypsin etc. (ii) Holoenzyme or Conjugate enzyme: These enzymes consist of proteinous part called apoenzyme and non-proteinous part called co-factor.
