4. 
   Enzyme
   A protein that catalyses a biochemical reaction. For example, chemical engineers make nitrogen (N2) into ammonia (NH3) using high temperatures and pressures - generating the power to make fertiliser by this process accounts for about 2% of all anthropogenic greenhouse gas emissions. Bacteria do the same thing at soil temperature and pressure using enzymes to catalyse the reaction.

8. 
   Enzyme
   Specific proteins which act as biological catalysts to regulate the rate of biochemical reactions in all living organisms by lowering the energy of activation. Enzymes may be biologically synthesised, extracted and employed to catalyse laboratory or industrial biochemical reactions.

11. 
    Enzyme
    a protein that controls and helps a chemical reaction to take place, but is not used up in the process. Usually each enzyme is specific for a particular step in a reaction. Enzymes are sensitive to their environment, especially to excessive temperature or pH.

    Enzyme
    Protein or protein-based molecules that speed up chemical reactions occurring in living things. Enzymes act as catalysts for a single reaction, converting a specific set of reactants (called substrates) into specific products. Without enzymes life as we know it would be impossible.The increase in rate can be as much as 10¹⁰ times that of...

22. 
    Enzyme
    A macromolecule, usually a protein, that functions as a (bio) catalyst by increasing the reaction rate. In general, an enzyme catalyzes only one reaction type (reaction selectivity) and operates on only one type of substrate (substrate selectivity). Substrate molecules are transformed at the same site (regioselectivity) and only one of a chiral sub...
