1. 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? (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.
2. 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. 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.

2. Explain at least two differences between Type I and Type II alveolar cells. a. Type I form the very thin simple squamous epithelium of the alveoli in junction with capillaries. Make up roughly 95% of alveolar epithelial cells. b. Type II produce and secrete pulmonary surfactant which is needed throughout the alveolar surface to keep the alveoli open. In addition, Type II cells can divide to replace damaged Type I cells. Make up roughly 5% of alveolar epithelial cells. Answer the following five true or false questions:

6. As the thoracic cavity expands and lung volume increases, the density of the gases filling the lungs decreases. True
7. When the diaphragm rises, thoracic pressure increases and air naturally flows out of the lungs. True (air naturally flows out of the lungs because of the pressure difference)

1. A doctor is looking to prescribe a larger dose of a vitamin that would not easily cause vitamin toxicity. What type of vitamin would be the best to prescribe? Explain your answer. A. Water soluble vitamin B. Fat soluble vitamin C. All of the above A. Water soluble vitamin. Fat soluble vitamins are stored within the body’s fat stores making it harder for the body to rid itself of them.
2. Explain which digestive system functions are carried out by the large intestine. Absorption: In the large intestine water and electrolytes are reabsorbed and vitamins are absorbed. Defecation: Feces travel to the rectum where it is excreted via the anus. Note: Essay answers must clearly be in your own words. Answer the following essay question:
3. Name and explain the four main functions performed by the digestive system. The digestive system has four main roles that it performs: ingestion, digestion, absorption, and defecation. Ingestion is when food enters the mouth. Digestion or food breakdown occurs when food is moved, mixed, and exposed to enzymes along the gastrointestinal tract. Digestion can be divided into two parts: mechanical and chemical digestion. Mechanical digestion occurs when food is broken down into smaller pieces. This occurs when the teeth chew food, when the stomach mixes food, and as food is moved along the gastrointestinal tract. Chemical digestion is the breakdown of food by enzymes. Absorption is the process of moving digested food into the blood stream. Defecation is the excretion of indigestible food from the anus. Answer the following three questions:
