Answer:
<h2>
Tetracycline affects the binding of tRNA to the ribosome.
</h2><h2>
Chloraamphenicol affect: growth of the protein chain.</h2>
Explanation:
1. Antibiotics block protein synthesis mostly in prokaryotes only as prokaryotes contain 70s ribosome.
2. Antibiotics are of various types, which have different targets in protein synthesis, some works on small sub-unit of ribosome and some on large sub-unit.
⇒Tetracycline would directly affect binding of tRNA to the A site on ribosome. tRNA brings amino acid to the ribosome which pairs with codon on mRNA.
⇒ Chloraamphenicol would directly affect growth of the protein chain because it block peptidyl transfer so the elongation of protein terminates.
Answer:
Proteins in a membrane are C. Both answer choice is true.
Explanation:
Membranes have different types of proteins. <em>Peripheral proteins are the ones that are placed on the inside suface held in place by the cytoskeleton. Integral proteins are the ones that are embedded in the membrane and protrude from either surfaces of the bilayer. </em>These integral proteins also can be carrier proteins, which facilitate passage of molecules through the membrane
; enzymatic proteins, whichcatalyze a specific reaction or they can recognize pathogens, baing cell recognition proteins. In the membrane we can find aquaporins too, which are membrane channel proteins that enable water to cross a membrane.
A Golgi apparatus receives proteins from the rough endoplasmic reticulum. The Golgi apparatus modifies, sorts, and packages the proteins to be sent out of the cell to be used. Hope this helps! :)
