Also inside the nucleus is the (chromatin/ chromosomes / nucleolus) which contains ribosomal RNA. The eukaryotic cell contains a variety of structures in the cytoplasm. The (ribosomes / golgi apparatus / mitochondria) are the site of protein synthesis and can be free floating or attached to the ER. The ER exists in two forms. One form contains ribosomes and is termed (rough / bumby / smooth) ER and the other is lacking ribosomes and is termed (silky / smooth / rough) ER. The ER packages substances that are sent to the packaging house of the cell. This organelle is the

Glycophorins are a type of membrane protein found on red blood cells. They allow red blood cells to circulate through the blood vessels without sticking to the walls of the blood vessels or to other cells. Describe how a glycophorin protein would be synthesized by the cell. Include What parts of the cell are involved and what happens at each location. The process of protein synthesis (i.e. transcription, translation, etc).
Now assume that the protein you are making is one that is not destined to be secreted into the extracellular space, but instead is meant to function within the cytoplasm. How will the synthesis of these types of protein be different? Why?

Each ribosome is specific for a particular type of protein where the ribosomes of the cytolasm are responsible for the synthesis of proteins that stay in the cell while ribosmes of the ER synthesize secretory proteins. Select one: True False
A peripheral protein, which is not integral to the cell membrane, is also called: a multi-pass transmembrane protein (like band 3.0 protein) a single-pass transmembrane protein (like glycophorin A) a monolayer-associated protein (like the COX-1 protein) a protein-attached protein (like cytochrome c) a lipid-linked protein (like the Ras protein)
Match the following with what organelle (one per blank) it is designated to go (letters can be used once, twice or not all): A. Lysosome B. Golgi body C. Endoplasmic reticulum mRNA transcript has a KDEL (amino acid code). protein is N- glycosylated protein has a mannose-6-phosphate sugar D. Nucleus MRNA a transcript has a long string of hydrophobic amino acids E. Peroxisome MRNA transcript encodes for a string of basic amino acids
If the location in which a protein functions is the endomembrane system then the protein is made on a ribosome attached to the outside of the rough endoplasmic reticulum. As the protein is made it is forced through a pore so that it ends up inside the RER. For each enzyme listed or described below state the kind of ribosome on which it's made (cytosolic, RER). If it's made on a RER ribosome, state the final destination of the protein in the endomembrane system. Protein Ribosome type Location in endomembrane system (if applicable) ACE2 receptor (human protein the SARS-CoV-2 spike protein latches on) A histone protein A mature acid hydrolase that will function as an intracellular lipase Cortisol synthesizing enzyme (hint, cortisol is a steroid lipid) Tubulin
Protein modifications that involve disulfide bonds occur in the following;(there may be more than one answer) golgi endoplasmic reticulum ) chloroplast (plastids) peroxisome mitochondria
Gaucher disease, caused by the inhibited digestion of lipids, results in the accumulation of fatty acids within many organs in the body and leads to their subsequent dysfunction. Which of the following describes the most likely subcellular component and related process responsible for the development of Gaucher disease? A B с D Lysosomes contain insufficient amounts of enzymes necessary for the metabolism of lipids. The Golgi complex produces vesicles with highly permeable membranes that cannot ef- fectively regulate the movement of particles. Mitochondria are not producing a sufficient amount of ATP required for the digestion of lipids. The rough endoplasmic reticulum contains an unusually high number of ribosomes, re- sulting in an overproduction of digestive enzymes.
The endoplasmic reticulum and Golgi apparatus are both membrane-bound organelles found in eukaryotic cells. Which statement describes one way in which the endoplasmic reticulum and the Golgi apparatus work together? The Golgi apparatus assembles mRNA, and the endoplasmic reticulum translates them into proteins. The endoplasmic reticulum assembles mRNA molecules, and the Golgi apparatus translates them into proteins. The Golgi apparatus assembles proteins, and the endoplasmic reticulum modifies and packages them. The endoplasmic reticulum assembles proteins and the Golgi apparatus modifies and packages them.
Describe the mRNA journey through the cell after the nucleus has given the instructions. Describe how each organelle affects the mRNA journey as it travel through the cell and, ultimately, through the cell membrane. Organelles you should mention include the nucleus, nuclear membrane, nucleolus, ribosomes, endoplasmic reticulum, cytoplasm, Golgi body, and plasma/cell membrane.
Describe the process of protein synthesis and trafficking of a protein, a lysosomal hydrolase, destined to be inside the lysosome. You do not need to detail the mechanism of translation but do state the role of the ribosome in getting your hydrolase to the lysosome. In your description please give some detail on the function and purpose of the organelles the protein will pass through and how it gets from organelle to organelle. In other words what happens to the protein along the way?
