e.Falsea.False- (ATP is produced, not ADP)b.Truec.False- (This process is called endocytosis)d.Truee.False- (Endocytosis is an active process and requires cellular energy)Question 3Not yet graded / 5 ptsNote: Essay answers must clearly be in your own words.In your own words, discuss Tay-Sachs disease. What organelle within the cell isimpacted? What are the symptoms of the disease and why do they occur?

Your Answer:Tay-Sachs occurs when a digestive enzyme in lysosomes is missing. Since thedigestive enzyme is missing, toxic lipids build up inside the cell which can lead tomental 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 presentdigestive enzymes inside lysosomes is lacking. Thus, a toxic lipid in thebrain cells cannot be broken down. The resulting buildup of lipids inthese cells can cause intellectual disability and death.Question 4Not yet graded / 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

one would you expect to be carrying out respiration at a more active rate, thelarger or smaller cell? Explain why.Your Answer:The smaller cell because as a cell grows larger the ratio of the surface area tovolume decreases. The smaller cell is able carry out respiration faster becauserelative to the larger cell it has a larger surface area compared to its volume andcan carry out respiration faster.The smaller cell. Cells need to remain relatively small because as a cellexpands the amount of surface area relative to the volume of the celldecreases. 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 occurfaster.Question 5Not yet graded / 5 ptsNote: Essay answers must clearly be in your own words.Explain what happens to the soft palate during swallowing. Why?Your Answer:
