The various parts of the endomembrane system serve different functions in the cell. In this activity, you will identify the role
Viktor [21]

Answer:

A) Lipid synthesis : Smooth endoplasmic reticulum.

B) Calcium ion storage : Smooth endoplasmic reticulum.

C) Poison detoxification : Smooth endoplasmic reticulum.

D) Protien synthesis : Rough endoplasmic reticulum.

E) Protien modification and sorting : Golgi apparatus

F) Cisternal maturation : Golgi apparatus.

G) Macromolecule digestion : Lysosomes

H) Autophagy : Lysosome.

Explanation:

<u>Smooth endoplasmic reticulum</u> is involved in the synthesis and storage of lipids . It also stores the calcium ions and contain enzymes responsible for the detoxification of the poisonous substances like CCL4 and other agents. SO the answer of A , B  and C is Smooth endoplasmic reticulum.

<u>Rough endoplasmic reticulum</u> contains ribosomes which synthesize protiens thus answer of D is RER.

The <u>Golgi apparatus</u> functions as a factory in which the protiens recieved from the endoplasmic reticulum are modified and sorted and is also involved in cysternal maturation so answer of option E and F is Golgi apparatus.

<u>Lysosomes</u> are the part of endomembrane system involved in the digestion of the macromolecules and in the recycling of the worn-out organelles hence also involved in autophagy. Hence answers of G and H is lysosomes.
