2022 Phase 2 1 question
-
If the pH in lysosomes is increased to alkaline, what will be the outcome?Lysosomal hydrolytic enzymes are active only at acidic pH and become inactive at alkaline pH.
2016 1 question
-
Which one of the following cell organelles is enclosed by a single membrane?
Lysosomes have a single membrane.
The lysosome is a spherical organelle covered by a single membrane containing degradative enzymes ('suicidal bags'). The other organelles are double-membrane bound.
2016 Phase II 1 question
-
A cell organelle containing hydrolytic enzymes is:
2002 AIPMT 1 question
-
Hydrolytic enzymes which act on low pH are called as : -Lysosomes contain many hydrolytic enzymes, such as lipases, proteases, carbohydrases and nucleases.
These enzymes work best at an acidic pH (about 4.5–5) maintained inside the lysosome, so they are called acid hydrolases.
Protease and amylase are particular types of hydrolytic enzyme, not the general name; peroxidase is an oxidoreductase.
So hydrolytic enzymes acting at low pH are called hydrolases (acid hydrolases).
2000 AIPMT 1 question
-
Lysosome contains :Lysosomes are membrane-bound vesicles formed from the Golgi apparatus.
They contain hydrolytic enzymes (acid hydrolases) such as lipases, proteases, carbohydrases and nucleases, which work at acidic pH and digest worn-out organelles, food particles and microbes.
So lysosomes contain hydrolytic enzymes.
