Which of the following function as receptors/ “cellular ID card” on cells?

Choose one of the following and answer the questions. (5 points) Answer these questions on the back of the scantron or on the extra paper provided.  1.) Marsha Mellow decides she must finally lose weight. Her friend tells her about this new diet. The diet is 30% fat, 65% protein and 5% carbohydrate. Marsha begins this diet and feels great the first day. The second day she feels extremely tired and has difficulty concentrating. Yet, she is determined to lose weight and continues with the diet. By day 5 of the diet she is so tired she can’t get out of bed and has horrible headaches. Her friend comes for a visit and notices that Marsha is very pale and has a strange fruity smell to her breath. During their visit, Marsha passes out and her friend calls 911. When Marsha enters the hospital many tests are done and she ultimately survives. Answer the following: 1. Why is Marsha tired and having headaches? (specifically which cells are affected by her diet) 2. What do you think her blood pH is when she is hospitalized? 3. What is Marsha’s diagnosis? 4. What caused this problem? (specifically, what is happening in her metabolic pathways: which pathway?) 5. What dietary advice would you give Marsha? 2.) Minnie mouse has finally had it with Mickey. She is tired of him getting all the attention while she does all of the work. One day she buys some rat poison and slips it into his cheesecake. Mickey eats the cheesecake and begins to gasp for breath. He turns blue and dies within minutes. Minnie knows that cyanide (in rat poison) blocks a key cytochrome which then causes death. (Minnie understood the metabolism lecture) Answer the following questions.  1. Where are cytochromes necessary? (name pathway and organelle) 2. List two minerals\metals that are components of cytochromes. 3. What would happen if a cytochrome was blocked and therefore nonfunctional? (describe what would happen to that pathway-be specific) 4. Why does this cause death? (what is the consequence of #3?) 5. What specific cells in the body are affected first?
