A cell containing an equal amount of solute as the solution Question 24 3 / 3 pts Using the letters given, match each molecule/item with its typical means of entering a cell. You may need to use some means of entry more than once. Correct! Lipid insoluble molecules Correct! Other cells Correct! Water Question 25 2 / 2 pts Which one of the following is not true of active transport? Hypotonic Isotonic Facilitated diffusion Endocytosis DiffusionThe sodium-potassium pump is an example Additional energy is needed to drive this process Correct! Active transport moves particles with the concentration gradient Active transport requires carrier proteins. Question 26 2 / 2 pts List the three organelles, in order, involved in the synthesis, transport and shipping of proteins. Correct! ribosomes, rough ER, Golgi complex rough ER, Golgi complex, lysosomes ribosomes, smooth ER, Golgi complex rough ER, Golgi complex, vacuole Question 27 5 / 5 pts Label the 5 organelles listed below: 1: __________2: __________ 3: __________ 7: __________ 9: __________ Your Answer: 1. nucleus 2. mitochondria 3. nucleolus 7. lysosome 9. golgi apparatus 1. Nucleus 2. Mitochondria 3. Nucleolus 7. Lysosome 9. Golgi Apparatus/ Golgi Complex Question 28 5 / 5 ptsTrue or False? a. Cellular respiration occurs in the mitochondria. (T or F) b. The purpose of cellular respiration is to produce ATP. (T or F) c. Integral proteins are only found on the inner surface of a cell membrane. (T or F) d. Endocytosis is the process that occurs to eject biomacromolecules from the cell. (T or F) e. Pinocytosis uses a signaling molecule from another cell, binding to the cell membrane to bring about changes within the cell proteins. (T or F) Your Answer: a. trua b. true c. false d. false e. false a. True b. True c. False- (Peripheral proteins are found on the inner or outer surface of the cell membrane. Integral proteins span the entire length of the membrane.) d. False- (This process is called exocytosis) e. False- (This process is called receptor-mediated endocytosis or information transfer) Question 29 5 / 5 pts Note: Essay answers must clearly be in your own words. In your own words, discuss Tay-Sachs disease. What organelle within the cell is impacted? What are the symptoms of the disease and why do they occur? Your Answer:Tay-Sachs disease is when a lipid digesting enzyme is missing or inactive then thr brain becomes impaired by an accumulation of lipids in the cells, It's very rare and normally passed down from parent to child. Resulting in buildup of lipids causing intellectual disability and/or death. the organelle is lysosomes disability, blindness, death, or paralysis could occur (1)Lysosomes (2) buildup of toxic lipids inside the cell (biomacromolecules) (3) disability and death In the genetic disease known as Tay-Sachs, one of the normally present digestive enzymes inside lysosomes is lacking. Thus, a toxic lipid in the brain cells cannot be broken down. The resulting buildup of lipids in these cells can cause intellectual disability and death. Question 30 5 / 5 pts Note: Essay answers must clearly be in your own words. You are observing two cells under the microscope. They are the same type of eukaryotic cell but one appears much larger. Based on appearance alone, which one would you expect to be carrying out respiration at a more active rate, the larger or smaller cell? Explain why. Your Answer: the smaller cell would be more active than the bigger cell. the cell needs to remain relatively small due to as the cell expands the surfacr area decreases relative to volume. The larger surface area allows metabolic processes to occur faster The smaller cell. Cells need to remain relatively small because as a cell expands the amount of surface area relative to the volume of the cell decreases. The smaller cell is more active because relative to its volume, its surface area is larger than a bigger cell. With a larger surface area (relative to its volume) this allows the metabolic processes to occur faster. Quiz Score: 98 out of 100 [Show Less]
