Question

Which of the following statements is not correct
w.r.t. palade particles?
(1) These are involved in protein synthesis
(2) They are also present in bacteria
(3) They are associated with intracellular
digestion of food
(4) They are also called organelles within the
organelle

Answer 1

Answer:

They are also present in the bacteria

Answer 2

The statement not correct w.r.t palade particles is option (3) They are associated with intracellular digestion of food. U

EXPLANATION

• Palade particles are also known as Ribosomes .
• The Ribosomes are granular structure present in all Eukaryotic and Prokaryotic cells.
• The main function of ribosomes is synthesis of protein.
• Ribosome is made up of two sub units that function as an entity to translate mRNA into a polypeptide chain.
• Bacteria (Prokaryotes) have 70s ribosomes, While in Eukaryotes have 80s ribosomes.
• In Eukaryotic cells the Ribosomes are present in other cell organelles such as mitochondria, chloroplasts and Rough Endoplasmic Reticulum. For this reason, Ribosomes are known as organelles within an organelle
• Lysosome is an enzyme that is associated with intracellular digestion of food in unicellular organisms such as Ameoba.

Hence, The incorrect statement is option (3) They are associated with intracellular digestion of food.
