10 Questions
What is the name given to inactive protease enzymes?
Zymogens
What is the process by which zymogens are activated?
Proteolytic cleavage
What is the main reason for the synthesis of zymogens as inactive precursors?
To prevent premature cleavage of proteins at the site of synthesis or secretion
Which of the following best describes the activation of zymogens?
It is an irreversible process
What is the primary purpose of the activation of zymogens?
To switch on processes at the appropriate time and place
Which of the following is a key feature of zymogen activation?
It occurs through specific proteolytic cleavage
What is the purpose of synthesizing proteases as inactive zymogens?
To prevent premature activation and cleavage of proteins
Which of the following best describes the activation mechanism of zymogens?
It requires specific proteolytic cleavage by an activator
What is the primary advantage of synthesizing proteases as inactive zymogens?
It prevents premature cleavage of proteins at the site of synthesis
Which of the following best describes the role of zymogens in biological processes?
They enable the appropriate timing and regulation of proteolytic events
Test your knowledge on the activation pathways of zymogen/proenzymes for various enzymes such as trypsin, chymotrypsin, carboxypeptidase, and elastase. Learn about the role of activators and the conversion of inactive proenzymes into active proteases.
