WebThe ribosome provides a set of handy slots where tRNAs can find their matching codons on the mRNA template and deliver their amino acids. These slots are called the A, P, and E sites. Not only that, but the ribosome also acts as an enzyme, catalyzing the chemical reaction that links amino acids together to make a chain. WebBecause active sites are finely tuned to help a chemical reaction happen, they can be very sensitive to changes in the enzyme’s environment. Factors that may affect the active site and enzyme function include: Temperature. A higher temperature generally makes for higher rates of reaction, enzyme-catalyzed or otherwise.
