Question
Chapter 8.3, Problem 2TQ
Summary Introduction
To review:
The regulation of production of ribosomal RNAs and ribosomal proteins when the growth rate has declined due to the limited availability of amino acids.
Introduction:
Translation is the process of translating the genetic information from the sequence of a mRNA (messenger ribonucleic acid) to the sequence of a polypeptide. tRNA (transfer ribonucleic acid) acts as an adapter molecule that reads the code from one end and brings the specific amino to the other.

Talk about a antibiotic that inhibits bacteria by inhibiting protein synthesis. Explain how these antibiotics interact with the protein synthesis machinery; what part of the protein synthesis machinery do they bind, and do all of these antibiotics bind to the same part of the machinery? How does this work to stop protein synthesis? Explain how it halts protein synthesis. Are these antibiotics bacteriostatic or bactericidal. Why and what does that mean for therapy?
Free ribosomes in the cytosol and ribosomes bound to the ER membrane have:
1) different types of small subunits but the same large subunits
2) the same types of large and small subunits
3) different types of large and small subunits
4) different types of large subunits the same small subunits

- What would happen to the cytoskeleton if you replaced all of the normal GTP in cells with a chemical variant of GTP that behaves in every way like normal GTP except that it cannot be hydrolyzed to GDP? It would prevent BOTH polymerization and depolymerization of microtubules. It would prevent microtubule polymerization. It would NOT affect EITHER polymerization or depolymerization of microtubules. It would prevent microtubule depolymerization.arrow_forwardProtein synthesis occurs in all living cells. Why, then, are some antimicrobial drugs that target protein synthesis selectively toxic to bacteria? The protein synthesis in human cells will only occur inside the nucleus. The ribosomes found in human cells and those found in bacterial cells have different structures. Protein synthesis in bacteria is completed by ribosomes, while protein synthesis in humans is completed by polymerase enzymes. The protein synthesis in human cells occurs less frequently than that in bacterial cells.arrow_forwardIn eukaryotic cells, ribosmes are found in the cytosol and on the rough endoplasmic reticulum. Where will the proteins synthesized at each location?arrow_forward
- Paramecium caudatum is a unicellular organism that can phagocytose and digest a bacterium using hydrolytic enzymes. Proteases are one example of hydrolytic enzymes that can break down proteins into polypeptides and amino acids. Name all of the organelles involved, in the order that the protease will go through. from its synthesis to its final destination. Note that this protease needs to be modified through the addition of a carbohydrate in order to be functional.arrow_forwardWhich of the following best describes a way in which a normal growth factor can stimulate cell division? A A growth factor can bind to membrane receptors and initiate a signal transduction path- way that causes the synthesis of division-facilitating enzymes. B с D A growth factor can supply necessary biomolecular building blocks for cell division by diffusing through the cell membane. A growth factor can facilitate the transport of glucose into the cell, thereby providing it with nutrients to support cell division. A growth factor can inhibit specific checkpoints in the cell cycle and allow the cell to skip or bypass certain cell cycle phases.arrow_forwardWhich is true of ribosomes found in eukaryotic cells? They: A) contain DNA B) synthesize carbohydrates C) are attached to the Rough Endoplasmic reticulum (RER) and carry out the synthesis of proteins D) are found inside the endoplasmic reticulum E) are originally found associated with the endoplasmic reticulum in prokaryotic cells.arrow_forward
- 3738: The lungs are composed of tiny sacs that fill with air during breathing process. How does this tissue help the lungs do its function? It allows the lungs to produce more blood. It allows muscles to open and close them. It allows air to contact a large surface. It allows the lung to pump the air. :)In response to critically low nutrient levels, yeast cells often enter into a dormant, non-dividing state. This state allows yeast cells to survive until nutrient levels are restored, at which point the cells typically re-enter the cell cycle. Based on the information above, critically low nutrient levels caused yeast cells to ________. transition to meiosis transition to G1 phase to G0 phase transition from G0 phase to G1 phase transition to mitosisarrow_forwardChoose the correct order of events for protein synthesis of an INTEGRAL MEMBRANE PROTEIN. 1. Translation occurs on a ribosome in the cytosol 2. Vesicle containing protein fuses with the Golgi apparatus. 3. Vesicle containing protein buds off the rough endoplasmic reticulum. 4. Vesicle containing protein fuses with the plasma membrane. 5. Transcription leads to generation of the MRNA. 6.

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.arrow_forward
- Shock (failure of the circulatory system) is an abnormal condition in which blood flow is inadequate. The most common causes of shock are massive blood loss and obstruction of blood flow. As a result of shock, there is a failure to provide cells with oxygen and nutrients. In this circumstance, cells swell and lysosomal membranes rupture, among other effects. Describe how energy is generated during shock and why cell structure becomes destabilized.arrow_forwardBriefly describe the function of the following in protein synthesis: a) rRNA, b) tRNA c) mRNAarrow_forwardIn addition to providing support, the cytoskeleton immobilizes enzymes and moves organelles to suitable positions in the cytoplasm.
