What are the 2 different ideal conditions enzymes depend on?
Enzymes work best within specific temperature and pH ranges, and sub-optimal conditions can cause an enzyme to lose its ability to bind to a substrate.
What type of compound is a enzymes?
All known enzymes are proteins. They are high molecular weight compounds made up principally of chains of amino acids linked together by peptide bonds.
Why do enzymes have different optimal temperatures?
At the optimum temperature, the kinetic energy in the substrate and enzyme molecules is ideal for the maximum number of collisions. At high temperatures the shape of the enzyme is altered so that it is no longer complementary to its specific substrate.
Why are proteins good enzymes?
The ability of proteins to undergo shape changes and reversibly so, make them most suited to function as enzymes among other things. Other biological macromlecules like sugars and fats are less suited for such a function.
What makes proteins the ideal types of compounds to act as enzymes?
enzymes What makes proteins the ideal types of compounds to act as enzymes? Proteins are large molecules that are able to bend into many different shapes. This enables the formation of active sites with specific shapes for specific substrates.
How does an enzyme speed up a chemical reaction?
A substance that speeds up the rate of a chemical reaction. Catalysts work by lowering a reaction’s activation energy. The reactants in an enzyme-catalyzed reaction. Substrates bind to a part of an enzyme called the active site and remain bound to the enzyme until the reaction is complete, when the products are released.
Substrates The reactants in an enzyme-catalyzed reaction. Substrates bind to a part of an enzyme called the active site and remain bound to the enzyme until the reaction is complete, when the products are released. How does the addition of a catalyst affect the energy of activation of a chemical reaction?
How are proteins able to bend into many different shapes?
Proteins are large molecules that are able to bend into many different shapes. This enables the formation of active sites with specific shapes for specific substrates. THIS SET IS OFTEN IN FOLDERS WITH… 2.4 Chemical Reactions and Enzymes
