Which of the following proteins would NOT be made on ribosomes that are bound to the rough endoplasmic reticulum? Question 13 options: A) a digestive protein that is found inside a lysosome B) insulin protein, which is secreted from the cell C) a protein that becomes part of the cytoskeleton D) an ion channel protein that is inserted into the cell membrane

Transcript

00:01 And in this answer we are going to see what kind of proteins are made by the bound ribosomes.

00:10 So, ribosomes are structures without membrane, that is they are not enclosed by a membrane and they are involved in protein synthesis.

00:26 So there are two types of ribosomes, namely the free ribosomes and the bound ribosomes.

00:32 The free ribosomes are found in the cytoplasm and they are not attached to any structures whereas the bound ribosomes are found attached to the rough endoplasmic reticulum.

00:46 So they stud the surface of the rough endoplasmic reticulum making it rough in appearance.

00:54 So the ribosomes have two subunits.

00:58 One is the large subunit which is involved in the polymerization of the amino acids into protein during translation and the small subunit which brings the aminoacile trna and binds it to the mrna codons.

01:23 So the bound ribosomes are involved in the synthesis of proteins that are secreted out of a cell that is secretary proteins or proteins which remain in the endomebrane system.

01:39 Or integrated into the cell membrane.

01:44 So option c, which says cytoskeleton protein, which remains in the cytoplasm, is not secreted by a bound ribosome because it is not secreted out of the cell, it remains in the cytoplasm and it is not enclosed in a endome membrane system.

02:09 So option c is the wrong option.

02:15 Option a which says enzyme that digest glucose in the cytoplasm is the correct option because digestive enzymes are extracellular which means they are synthesized and secreted outside the cell...
