An enzyme is a biological catalyst. It speeds up a reaction by lowering the activation energy required to start the reaction. It speeds up a reaction, but remains unchanged unless certain limiting factors are introduced. It is composed of polymers of amino acids. An enzyme has an optimum pH ...
Explain how an enzyme speeds up a reaction as a catalyst. Coenzymes: Coenzymes are organic molecules that help the enzymes to act as catalysts by binding to the active sites of the enzymes. Enzymes are mostly protein in nature, whereas coenzymes are mostly nonprotein molecules. Mostly vitamins...
speeds up reactions by lowering activation energy activation energy energy needed for reaction to begin names of enzymes end in "ase", identify the reactant, and describes their function metabolism the sum of all chemical reactions taking place continuously in a cell or an organism enzymes ending ...
a reaction. Enzymes speed up reactions by lowering the energy barrier allowing reactions to progress. An important property of enzymes is that although they can cause chemical changes in other molecules, they are unchanged by the reaction. As a result, a singleenzymecan catalyze the transformation...
What is the role of enzymes as a catalyst? Explain how an enzyme speeds up a reaction as a catalyst. What is the molecule that the catalyst/enzyme acts on called? a. activation energy b. enzyme c. substrate d. active site What are the properties of an enzyme that make it a good bio...
substance that speeds up rate of chemical reaction and is NOT altered by the reaction Ferric oxide is a chemical catalyst (rust outside iron nail) Catalase is a biological catalyst/enzyme that converts H2O2 into H2O and O2 enzymes speed up reactions by activation energy active site place where...
An enzyme speeds up the rate of the chemical reactions by lowering the reaction’s activation energy‚ which means that by definition‚ an enzyme functions as biological catalyst. The activation energy is the energy that is used to get a reaction started. The function of an enzyme is ...

A molecule that is essential for the activity of some enzymes; it may exist free in solution within a living organism, but functions by binding to an enzyme to assist in catalyzing a reaction. The molecule itself may be temporarily changed during the reaction, but is ultimately restored to it...
