Question

questions, and 5 free-response questions. D Question 6 The lysosome... O membrane contains H+ pumps that use the energy of ATP hydrolysis to pump protons out of the organelle and into the cytosol degrades proteins, carbohydrates, and nucleic acids, but phospholipids cannot be hydrolyzed in this compartment. O can degrade misfolded proteins but not damaged organelles. O contains hydrolytic enzymes that are synthesized as zymogens. O contains hydrolytic enzymes that function optimally at neutral pH.

Answer 1

Option D.

Lytic enzymes are secreted as inactive zymogens. Activators convert these zymogens to active hydrolases.

Lysosomal membrane contains proton pump which transports proton from cytosol into the lysosome.

Lysosomal enzymes can degrade phopholipids and other organelles.

Lysosome has internal pH of ~ 5, which is acidic. Therefore, enzymes of lysosome are acid hydrolases.
