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

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)

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.
In the eukaryotic cell, the members of the endomembrane system work together to synthesize protein products used for excretion out of the cell (e.g. insulin, milk etc.) and for use within the cell (e.g. lysosomes etc.).

Cancer cells treated with vitamin E succinate are generally more vulnerable to rupture of their lysosomal membranes (and subsequent apoptosis) than are normal cells, because: cancer cells often have an acidic cytosol, and their lysosomes have an acidic pH too cancer cells often have an acidic cytosol, but their lysosomes have an alkaline pH cancer cells often have an alkaline cytosol, and their lysosomes have an alkaline pH too cancer cells often have an alkaline cytosol, but their lysosomes have an acidic pH all of the above

If cells are treated with colchicine, a drug that promotes microtubule disassembly, the location of the ER and Golgi both change dramatically. Rather than being spread out quite widely through the cytoplasm, the ER appears to collapse into the area near the nucleus. (Recall that the ER membrane and the outer nuclear envelope are continuous with one another). In contrast, the Golgi stacks disperse from their usually more compact, central location to areas all over the cell. However, if colchicine is removed, and microtubules are allowed to reassemble, both organelles eventually return to their normal distribution in the cells. How do you account for the change in distribution of the ER & Golgi when microtubules are depolymerized? What protein(s), other than tubulins, allow normal cellular organization to be restored once colchicine is removed? (answer should include information to explain both the ER & Golgi)
A main function of the cell membrane is to be very selective as to what is able to cross through, a condition known as a barrier. In the fluid mosaic membrane model, lipids are organized in a arrangement, such that portions of the lipids are exposed to either the interior or exterior of the cell, while the lipid portions are sandwiched in the middle of the membrane. As part of the cell membrane, a main function of proteins is to provide while a main function of proteins is to provide Other cell membrane molecules include which function to provide fluidity to rigid membranes and rigidity to fluid membranes; and surface carbohydrates, which function to provide . Aminophospholipids move to the inner leaflet of the membrane, by an enzyme known as the
