Q. How can the activity rate be increased by enzyme?
Initially, an increase in substrate concentration leads to an increase in the rate of an enzyme-catalyzed reaction. As the enzyme molecules become saturated with substrate, this increase in reaction rate levels off. At low temperatures, an increase in temperature increases the rate of an enzyme-catalyzed reaction.
Q. What does increased enzyme activity mean?
Increasing Enzyme Concentration will increase the rate of reaction, as more enzymes will be colliding with substrate molecules.
Q. Why is there a maximum for enzyme activity?
The rate of an enzyme-catalyzed reaction increases with an increase in the concentration of an enzyme. At higher temperatures, the protein is denatured, and the rate of the reaction dramatically decreases. An enzyme has an optimum pH range in which it exhibits maximum activity.
Q. What happens to enzymes at 100 degrees Celsius?
When a protein is heated beyond its normal temperature range, heat will increase the kinetic energy of atoms in the protein, causing molecular motion that breaks the various bonds that hold the protein in shape. whereas human proteins, adapted to life at 37 degrees Celsius, denature at 100 degrees Celsius.
Q. What temperature do enzymes work best?
about 98.6 degrees Fahrenheit
Q. What is it called when the protein structure of an enzyme breaks down?
A process called catalysis happens. It could be broken down or combined with another molecule to make something new. It will break or build chemical bonds.
Q. What are 2 properties of enzymes?
General Properties Of Enzymes
- Enzymes initiate and accelerate the rate of biochemical reaction.
- The activity of enzymes depends upon the acidity of medium (pH specific).
- Enzymes can accelerate the reaction in either direction.
- All enzymes possess active sites which participate in the biochemical reactions.
Q. How can you tell if a protein is an enzyme?
Enzymes are protein molecules – long chains of amino acid residues. Groups like these help a substrate to attach to the active site – but only if the substrate molecule has an arrangement of groups in the right places to interact with those on the enzyme.
Q. How do you know a protein is an enzyme?
As a general rule, the “-ase” suffix identifies a protein as an enzyme, whereas the first part of an enzyme’s name refers to the reaction that it catalyzes. Enzymes lower the activation energy necessary to transform a reactant into a product.
