Cell The Unit Of Life Question 114
Question: The acidic condition within the lysosome is maintained by:
Options:
A) digestive enzymes synthesised on RER.
B) pumping $ C{l^{-}} $ ion out of lysosome.
C) pumping protons $ ({H^{+}}) $ into the lysosome.
D) All of the above
Show Answer
Answer:
Correct Answer: C
Solution:
[c] The lysosome is filled with 40 types of acid hydrolases (digestive enzymes).
The acidic pH 5 (4.6 to 5) is due to the action of ATP proton pump in the membrane of the lysosome.
All the enzymes do not occur in the same lysosome.
There digestive enzymes are synthesised on RER and packed into lysosomes.
