Choose the wrong one.
A. Lipid biosynthesis occurs in peroxisome
B. Removal of toxic chemicals is done by SER
C. Lysosome is suicidal bag
D. Protein synthesis takes place by ribosomes
Answer: Option A
Solution (By Examveda Team)
a. Lipid biosynthesis occurs in peroxisome is wrong.The endoplasmic reticulum (ER) is the main site for lipid synthesis. Intracellular lipid trafficking is necessary to maintain most other organelle membranes as they cannot synthesize lipids de novo.
b. Removal of toxic chemicals done by SER is true.
SER is a membrane-bound network of tubules without surface ribosomes. SER is not involved in protein synthesis. Its main function is the synthesis of lipids, steroids, and carbohydrates, as well as the metabolism and removal of exogenous substances, such as drugs or toxins.
c. Lysosome is suicidal bag is correct.
Lysosomes are capable of digesting nucleic acid, polysaccharides, fats and proteins. Along with them lysosomes also digest or damage their cells with their enzymes, which leads to cell death.
d. Protein synthesis taking place by ribosomes is also correct.
The ribosome is universally responsible for synthesizing proteins by translating the genetic code transcribed in mRNA into an amino acid sequence.
