- Ribosomes in the cytoplasm capture mRNA that can be translated into an enzyme for the lysosome. a) Explain what happens from the time the enzyme begins to form in the cytoplasm until it ends up in the lysosome and also explains how the enzyme is transported to the lysosome?arrow_forwardYou are studying a cytoskeletal accessory protein, AB2. You believe it is involved in receptor-mediated endocytosis allowing for the entry of a novel virus, SARS-CoV X, into the host cell. To confirm that AB2 is required for viral entry, you engineer an AB2 protein containing an N-terminal hydrophobic signal sequence and a C-terminal KDEL sequence (AB2-SSKDEL) and express it in human epithelial airway cells. You compare cells expressing wild-type (WT) AB2 (lacking the signal sequence and KDEL sequence) with cells expressing AB2-SSKDEL. You are looking at the entry of a GFP (green) virus into cells. If AB2 is required for viral entry, via receptor-mediated endocytosis, what results would you expect to see in terms of viral entry? A. WT AB2 - Green ER AB2-SSKDEL - No green ER B. WT AB2-NO green cells AB2-SSKDEL - Many green cells OC. WT AB2 - Many green cells AB2-SSKDEL - NO green cells D.WT AB2 - Green nuclei AB2-SSKDEL - No green nucleiarrow_forwardA useful technique for studying microtubule motors is to attach them by their tails to a glass coverslip (which can be accomplished quite easily because the tails stick avidly to a clean glass surface) and then allow them to settle. The microtubules may then be viewed in a light microscope as they are propelled over the surface of the coverslip by the heads of the motor proteins. Because the motor proteins attach at random orientations to the coverslip, however, how can they generate coordinated movement of individual microtubules rather than engaging in a tug-of-war? In which direction will microtubules crawl on a ‘bed’ of kinesin molecules (i.e., will they move plus-end first, or minus-end first)?arrow_forward
- How many ribosomes are actively synthesizing proteins at any instant in an E. coli cell growing with a 45-min doubling time? The birth size of E. coli is 1-μm diameter and 2-μm length. The water content is 75%. About 60% of the dry material is protein, and the rate of amino acid addition per ribosome is 20 amino acids per second. The average molecular weight of free amino acids in E. coli is 126.arrow_forwardIdentify the following by describing their functions: EF-G, EF-Tu, EF-Ts, EF-P, and peptidyl transferasearrow_forwardYou treat a cell with a fluorescently-labelled antibody that recognizes microtubules, and you observe what appears to be a spindle apparatus. Is the cell a prokaryote or a eukaryote? Explain. Some archaebacteria species live in extremely high-salt environments. Cite a specific example of protein modification that has allowed these bacteria to accomplish this.arrow_forward
- As a researcher who studies cytoskeletal dynamics, you create a microtubule subunit that cannot hydrolyze GTP. How would the critical concentration for the minus end of a polymer formed by these mutant subunits compare to that of the minus end of a fiber formed by normal microtubule subunits? Why? How would the critical concentration for the minus end of a fiber formed by these mutant subunits compare to that of the plus end of a fiber formed by normal microtubule subunits? Why?arrow_forwardEach type of molecule listed below is recognized by a specific class of nuclear import receptor (importin) or nuclear export receptor (exportin). For each type of molecule, state whether you think it is recognized by an importin or exportin and explain why (in terms of where that molecule is synthesized, what that molecule does, and where it does it). (a) RNA polyermase II: (b) ribosomal protein: (iii) †RNA:arrow_forwardList and describe the three main types of cytoskeleton. If you wanted to do immunocytochemistry to specifically stain each type of cytoskeleton, what is a protein that could be used for each cytoskeletal type (in other words, what is a unique protein for each cytoskeletal type)? What are three types of actin structures? Describe the involvement of actin structures in cell migration. How is the growth and shrinking of microtubules regulated? Then describe the roles of microtubules in: chromosomal separation during mitosis and the movement of organelles and vesicles within a cell. Describe a possible mechanism on how signaling pathways might impact the cytoskeleton, so that cell migration could be regulated in a localized manner within a multicellular organism. (hint: think about the possible transcriptional regulation of the G-protein regulators) What are 2 main challenges of protein targeting? Then describe one way these challenges are overcome during signal-based targeting and one way…arrow_forward

The cell wall is thus fragile and the bacteria die. Penicillin and its derivatives are structural analogs of the natural substrates of these enzymes. Why doesn't penicillin normally kill humans, unless a severe allergic reaction (anaphylaxis) develops? How does penicillin inhibit transpeptidase?arrow_forwardA typical human hepatocyte (liver cell), a widely studied eukaryotic cell, has a diameter of about 20 μm. Calculate the volume of both a prokaryotic and a eukaryotic cell. To appreciate the magnitude of the size difference between the two cell types, estimate how many bacterial cells would fit inside the liver cell.
