- Which describes an enzymatic activity/biochemical function of importin-beta? O hydrolyze GTP to GDP + Pi interact with/bind to nuclear localization sequences INLSS) interact with/bind to importin-alpha facilitate release of nuclear proteins after transport through the nuclear pore complexThe synaptosome-associated receptors referred to as v-SNARES are transmembrane proteins located on which of the following eukaryotic cell structures? mitochondrial membranes chloroplast membranes vesicle membranes lysosomal membranes peroxisomal membranesExplain the reason why mitochondria requires a special translocator to import proteins across the outer membrane, when the membrane already has porins.
- Some drugs can prevent the formation of new lysosomes. However, a cell would continue to make hydrolytic enzymes from the DNA still contained in the cell. Where would you most likely find these enzymes after the drug treatment? O Golgi Complex O Smooth Endoplasmic Reticulum O Nucleus O Mitochondrion Strikingly different signaling systems can operate in similar ways. For example, ethylene gas released by ripening fruits diffuses through the air from plant toThe high permeability of the outer membrane of the mitochondria aids in the function of this organelle by . Group of answer choices Allowing for transport of ATP in and food out of the mitochondria Allowing for transport of food in and ATP out of the mitochondria Allowing for transport of food in and ATP out of the mitochondria Allowing more export of mitochondrial DNA out of the mitochondria to the nucleusThe organelle labelled mitochondria is involved in an important cell process. Identify the process that takes place in this organelle’s inner matrix.
- Which describes an enzymatic activity/biochemical function of importin-beta? facilitate release of nuclear proteins after transport through the nuclear pore complex interact with/bind to nuclear localization sequences INLSS) interact with/bind to importin-alpha hydrolyze GTP to GDP + PiApplying Clinical Reasoning Kevin S. and his wife have been trying to have a baby for the past 3 years. On seeking the help of a fertility specialist, Kevin learned that he has a hereditary form of male sterility involving nonmotile sperm. His condition can be traced to defects in the cytoskeletal components of the sperms flagella. As a result of this finding, the physician suspected that Kevin also has a long history of recurrent respiratory tract disease. Kevin confirmed that indeed he has had colds, bronchitis, and influenza more frequently than his friends. Why would the physician suspect that Kevin probably had a history of frequent respiratory disease based on his diagnosis of sterility from nonmotile sperm?Very briefly, explain how increased cytoplasmic IP3 levels can then increase cytoplasmic calcium (Ca2+) levels.
- 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.A human gene called theCFTR gene (for cystic fibrosis transmembrane regulator) encodes aprotein that functions in the transport of chloride ions across the cellmembrane. Most people have two copies of a functional CFTR geneand do not have cystic fibrosis. However, a mutant version of the CFTRgene is found in some people. If a person has two mutant copies ofthe gene, he or she develops the disease known as cystic fibrosis. Arethe following descriptions of this disease related to genetics at themolecular, cellular, organism, or population level?A. People with cystic fibrosis have lung problems due to a buildupof thick mucus in their lungs.B. The mutant CFTR gene encodes a defective chloride transporter.C. A defect in the chloride transporter causes a salt imbalance inlung cells.D. Scientists have wondered why the mutant CFTR gene is relativelycommon. In fact, it is the most common mutant gene that causesa severe disease in persons of Northern European descent.
