Question

4. What are the differences between ribosomes that make secretory proteins and those that make proteins intended for the cytosol?

Answer 1

Answer-

According to the given question-

(4) Ribosomes - Ribosomes are made up of ribonucleic acid (RNA) and proteins and are responsible for protein synthesis. ribosomes have two subunits. In prokaryotes carry 70S ribosomes which is made up of 30 S and 50 S subunit while in eukaryotes have 80S ribosomes which is mede up of 40 S and 60 S subunit.  some ribosomes are present in the cytoplasm of cell while some are attached to the Endoplasmic reticulum. The free flowing ribosomes of cytoplasm and the bounded ribosomes of endoplasmic reticulum have same structure and responsible for protein synthesis.

So the correct answer for the question is (B) Thesre is no difference between the ribosomes producing secretory proteins and those producing cyosolic proteins.

(5) According to the question a synthetic vesicle which is made up of pure phospholipid have 1 mM glucose and 1 mM sodium chloride and later placed in the water. we know that the concentration of solute inside the vesicle is very high because it have glucose and sodium chloride compared to the outside where only water if present or in other word we can say that the concentration inside the vesicle is higher compared to the outside which created a concentration gradient that causes rapid movement of water from outside to inside the vesicle.

So the correct answer is (C) Water diffuses in
