Q

Structure of lysosome

A

Has vacuole bound by membrane reservoir of approximately 50 hydrolytic enzymes which are optimum functional at acidic PH

For example acid hydrolases like amylase nucleus Peptodasd lipase

Q

What is pyelonephritis. How is it caused.

A

It is the inflammation of kidney.
It is caused due to the malfunctioning of lysosomal enzyme degenerative disorder

17
Q

Autophagic lysosome

A

Found by the union of primary lysosomes around dead or old organelles which surround them with vacuolar membrane and digest them by autolysis or autodigestion.

18
Q

primary lysosomes

A

Newly synthesis lysosome with inactive enzymes
