This can lead to disability and death.(1)Lysosomes(2) buildup of toxic lipids inside the cell (biomacromolecules)(3) disability and deathIn the genetic disease known as Tay-Sachs, one of the normally present digestiveenzymes inside lysosomes is lacking. Thus, a toxic lipid in the brain cells cannotbe broken down. The resulting buildup of lipids in these cells can causeintellectual disability and death.Question 45 / 5 ptsNote: Essay answers must clearly be in your own words.You are observing two cells under the microscope. They are the same type ofeukaryotic cell but one appears much larger. Based on appearance alone, which onewould you expect to be carrying out respiration at a more active rate, the larger orsmaller cell? Explain why.Your Answer:The smaller cell would carry out respiration at a more active rate. This is because of theincreased surface area compared to larger cells.The smaller cell. Cells need to remain relatively small because as a cell expandsthe amount of surface area relative to the volume of the cell decreases. Thesmaller cell is more active because relative to its volume, its surface area is largerthan a bigger cell. With a larger surface area (relative to its volume) this allowsthe metabolic processes to occur faster.Question 55 / 5 ptsNote: Essay answers must clearly be in your own words.
