Intracellular & Extracellular Enzymes Flashcards
1
Q
What are intracellular enzymes?
A
enzymes that catalyse reactions inside cells
within the cell
2
Q
What are extracellular enzymes?
A
enzymes made inside cells but catalyse reactions outside of cells
usually exported by exocytosis
3
Q
What is an example of an intracellular enzyme?
A
catalas
2H2O2 -> 2H2O + O2
Hydrogen peroxide is a harmful waste product of cell metabolism
4
Q
What is an example of an extracellular enzyme?
A
e.g. amylase
starch -> maltose
made by cells in salivary glands and secreted into mouth / small intenstine
e.g. trypsin
long polypeptides -> short polypeptides
made in pancrease and secreted into small intenstine and hydrolyses peptide bonds
