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.
DNA replication goes in the 5' to 3' direction because DNA polymerase acts on the 3'-OH of the existing strand for adding free nucleotides. DNA replication can take place both the directions chemically. ... But these nucleotide triphosphates hydrolyze spontaneously under aqeuous conditions.
