Strings of 50 or more amino acids are known as proteins, large molecules that serve the functions of promoting normal growth, repairing damaged tissue, contributing to the body's immune system, and making enzymes. The latter are a type of protein that functions as a catalyst, a substance ...

What are Enzymes? What is an enzyme, and how does it work? The definition of anenzymeis a protein that serves as a biologicalcatalyst, meaning that it makes a chemical reaction occur more quickly without being consumed or otherwise permanently altered by it. Each type works to facilitate a ...
Enzymes are a Special Type of Protein Enzymes are a type of catalyst, which is a substance that speeds up the rate of a chemical reaction. Enzymes are. Enzymes. Enzymes. A catalyst lowers activation energy. Enzymes. What is an enzyme? Enzymes are proteins, which means they are organic. C...
Oligonucleotide catalysts such as ribozymes and DNAzymes can cleave RNA efficiently and specifically but are typically dependent on high concentrations of divalent cations, limiting their biological applications. A modular XNAzyme catalyst composed of 2′-deoxy-2′-fluoro-β-d-arabino nucleic acid (FAN...
Figure 1: Two diagrams showing the activation energy both with and without an enzyme. With the enzyme, the activation energy is much lower, so the reaction occurs at a faster rate. Definition: Enzyme An enzyme is a biological catalyst that speeds up the rate of a reaction without being used...
Function of Enzymes Enzymes make rxns go faster by reducing the amount of activation energy needed for the reaction to start Activation Energy What’s needed to get the rock rolling down the hill on its own? ENERGY INPUT Enzymes are Biological Catalysts A catalyst speeds up the rate of the ...
