Quiz 6 Saved Match the term to the phrase that most accurately describes it to test your understanding of enzyme terminology. Endoenzyme Enzymes which function inside a cell Regulated enzyme Enzymes which are always present in a cell in relatively constant amounts Exoenzyme The production of these enzymes can be turned on or off as needed Constitutive enzyme Enzymes which are secreted and function outside a cell Reset

Answer 1

Endoenzyme----- Enzymes which function inside a cell.

Regulated Enzyme----- The production of these enzymes can be turned on or off as needed.

Exoenzyme----- Enzymes which are secreted and function outside a cell.

Constitutive Enzyme----- Enzymes which are always present in a cell in relatively constant amounts.

Detailed Explanation for the answer:

Endoenzymes: (Endo- means Internal) enzymes are also known as intracellular enzymes i.e. they carry out all their catalytic functions inside the cell in which they were originally produced or originated. For e.g. Endoamylase.

Exoenzyme: (Exo- means External) Since some enzymes function inside the cell, so they are categorised as endoenzymes while some are produced by the cell but function outside the cells. Therefore they are known as Exoenzymes. For e.g. Proteases, Cellulases.

Regulated Enzyme: Regulatory Enzymes are responsible for controlling certain functions in the cells or can be used to switch off or switch on a process or a biochemical pathway. There the production of these enzymes can be turned off and on according to requirements. for eg Feedback Inhibition The production of enzyme inhibited by the end product of the catalytic reaction, whenever its concentration exceeds its requirements in the cells. For e.g. Kinases

Constitutive Enzymes: Constitutive enzymes are those which remain constant in its production rate and in amount even if a substrate is present or not. They are always present in constant amounts. Foe e.g. Glycolytic Enzymes.
