Section Four (enzymes) Flashcards
Enzymes speed up the rate of biological reactions, so are therefore known as what?
Biological catalysts.
What part of the enzyme does the substrate bind to?
Active site.
Which molecule binds to the active site of the enzyme?
Substrate.
What word means the active site has changed shape?
Denatured.
State the variable that you measure.
Dependent.
State the variable that you change.
Independent.
State the variable you keep the same.
Control.
State the enzyme that catalyses the breakdown of starch to glucose.
Amylase.
State the general name of the pH where the rate of reaction is at its highest.
Optimum pH.
State the general name of the temperature where the rate of reaction is at its highest.
Optimum temperature.
State the solution that tests for the presence of starch.
Iodine solution.
What colour will the iodine turn if starch is present?
Blue/black.
