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=false 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 3 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: its impacts the lysosomes and its as a results of buildup of lipids inside the cells and it causes death or in some cases disabilities. it is generally consided a genetic disease where one of the normal digestive enzymes inside the lysosomes is lacking. (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. 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 this is because it has a relatively small surface area to the volume of the cell is decrease. thus a smaller cell is more active because relative to its volume the surface area is larger than that of the bigger cell and this helps metabolic process to happen 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. Label A- Label C- Label E- Label F- Label H- Your Answer: A=nasal cavity C=soft palate E=glottis F=trachea H=tongue Look carefully at the diagram below. Label the following 5 organs of the digestive system. To receive credit for the intestines you must label the specific region. 1: 2: 5: 6: 8: Your Answer: 1=liver 2=pancreas 5=Duodenum 6=lleum 8=ascending colon Your Answer: 2=nasal bone 4=zygomatic bone 6=inferio nasal concha 7=maxilla 8=mandible 2: Nasal bone 4: Zygomatic bone 6: Inferior nasal concha 7: Maxilla 8: Mandible Question 13 5 / 5 pts Label the bones in the figure below: A: B: C: D: E: Your Answer: A=trapezium B=scaphoid Question 17 5 / 5 pts Would you expect a female to have testosterone in their bloodstream? Explain why or why not. Your Answer: yes because both male and females bodies produce all sex hormones but they only vary in the ratios as the adrenal glands are know to be responsible for producing this opposite hormone that the ovaries would normally not. (1) Yes. Both male and female bodies produce “all” the sex hormones. However, the ratios are different. (2) The adrenal glands are largely responsible for producing this “opposite” hormone that the ovaries would not. Quiz Score: 134 out of 140
