The peptidyl transferase reaction is an exemplification that the ribosome is a ribozyme. True False

Fatty acids that are ester-bonded to glycerol (as glycerol-3-phosphate membrane lipids) can be found in all of the following eukaryotic organelles except: the mitochondrion the ribosome the peroxisome the nucleus the lysosome

Proteins that have been damaged, and usually marked with ubiquitin, are destined to be broken down and recycled in which of the following eukaryotic structures? the peroxisome the chromosome the lysosome the proteasome the ribosome

The true nucleus is generally absent in E.coli and other prokaryotes.Comment.

Select the correct statements regarding the transport of proteins to the ER shown in the diagram below.

Which side (in or out) of every living prokaryotic cell has more hydrogen, sodium, potassium, and calcium.

Identify the protein component of the transmembrane complex used by the salt-loving archaean Halobacterium halobium, which uses sunlight to create a proton gradient for ATP synthesis. bacteriochlorophyll bacteriorhodopsin cytochrome c chlorophyll retinal

Explain why the statement is correct. Which is true of the ribosomes of endoderm cells of the Cnidaria (jellyfish)? They: are attached to the Rough Endoplasmic reticulum (RER) and carry out the synthesis of the primary structure of proteins

Peptidoglycan (PG) is a heteropolymer that consists of glycan strands cross-linked by short peptide fragments and makes up the cell wall of archae . True  False

N-linked glycosylation of proteins occur in the ER. The attached oligosaccharides are further processed as these proteins travel through the Golgi apparatus.   true   false
