Question

Circle the letter of each sentence that is true about lysosomes.
2. They contain enzymes that help synthesize lipids.
b. They break down organelles that have outlived their usefulness.
c They produce proteins that are modified by the ER.
d. They contain enzymes that break down lipids, carbohydrates,
and proteins.

Answer 1

Answer:

The correct answer is b They break down organelles that have outlived their usefulness.

Explanation:

Lysosomes are digestive organelle that play an important role in intracellular digestion also called Autophagy.

                         Lysosome contain many hydrolytic enzymes such as acid hydrolase that aid in the digestion of various cellular constituents.

                      During autophagy double membrane autophagosome containing phagophore that play an important role in engulving the material destined to be degraded,form around that organelles that are either dysfunctional or no longer important for the cell .  autophagosome then fuse with lysosome to form phagolysosome in which the contents of autophagosomes are digested by the catalytic activity of Acid Hydolase enzyme .
