How do bacteria survive in the body? - Answer Bacteria survive by utilizing their cytoplasmic membrane, cell walls, DNA replication, motility, and mechanisms of adaptation. What is the significance of the cytoplasmic membrane in bacteria? - Answer The cytoplasmic membrane performs functions typically divided among eukaryotic plasma membranes and organelles, including oxidative metabolism and nutrient transport. What challenges do microbes face in nutrient acquisition? - Answer ...

In which of the following organelles does transcription occur? Golgi apparatus Lysosome Peroxisome Nucleus Ribosome - Answer Nucleus Carbohydrate side chains attached to proteins and lipids are found on the outer surface of the plasma membrane on the inner surface of the plasma membrane on both sides of the plasma membrane are not found in the plasma membrane - Answer on the outer surface of the plasma membrane Oxidation reactions always involve the ...

The cytoskeletal system characterized as being comprised of rope-like fibers that give the cell mechanical strength and distribute mechanical stress are: - Answer intermediate filaments Which of the following statements about the cytoskeleton is FALSE - Answer Covalent bonds between protein monomers hold together cytoskeletal filaments For both actin and microtubule polymerization, nucleotide hydrolysis is important for - Answer decreasing the binding strength between sub...

Where are proteins synthesized within the cell? Mitochondria Chloroplasts Cytosol Endoplasmic reticulum All of the above - Answer All of the above If you wanted to study the detailed internal membrane structure of a chloroplast, what kind of microscopy would be most appropriate? - Answer Electron T/F: Chloroplasts are thought to have arisen by engulfment of a photosynthetic bacterium by an ancestral eukaryotic cell. - Answer True The relative molecular mass of...

Different types of cell in your body (skin, liver, muscle etc.) have very different features. What might be the explanation for this? - Answer Each type of cell has the same genome but express a different set of genes Based on this theory, would you predict that the mitochondrial inner membrane is derived from - Answer Engulfed bacterium Animal cells contain mitochondria, whereas plant cells do not - instead they contain chloroplasts. - Answer False So - secreted pro...

All of the following about receptor tyrosine kinases is true EXCEPT A. their activated form is usually a dimer B. they bind an extracellular ligand C. they transphosphorylate their partner D. they phosphorylate the amino acid Tyr E. when activated they will bind a trimeric G protein - Answer E The two membrane-bound enzymes that are the main targets for activated G proteins are A. protein kinase A and odorant receptor kinase B. chymotrypsin and trypsin C. ...

What are the specificity properties for membrane transporters vs membrane channels for their respective transported solute? - Answer Transporters have specific binding sites; channels allow substance in based on ion charges or size of molecules If a stimulus causes the membrane of the neuron below to depolarize to -50 mV, would action potential be generated? - Answer No What is the main function of lysosomes? - Answer Protein degradation Imagine you are studying the tr...
