True
Step-by-step explanation:
Substrates are molecules which bind to the active site of an enzyme and are chemically changed as a result of that binding. -The active site of each enzyme is specific for specific substrates. -The substrate often fits into a pocket or a groove on the enzyme. -Often the name of the substrate shows up in the name of the enzyme; for instance, catechol is the substrate for catechol oxidase. -A cofactor can be considered a substrate because it also binds to an enzyme.B.)Which of the following statements are true about binding sites on enzymes? (Mark all correct responses) -An active site is the location on an enzyme to which a specific substrate binds -On many enzymes, there are binding sites away from the active site to which molecules can bind and alter the activity of the enzyme. -The rate at which molecules bind to enzymes is influenced by the concentration of that particular molecule -The shape of the active site (and therefore the rate of binding of the substrate to the active site) can be changed by changing the shape of the enzyme -Molecules with similar shape will compete for binding sites on the the enzyme
