Textbook Question
Chapter 7, Problem 20CTQ
Because they lose their mitochondria during development, red blood cells cannot perform aerobic respiration; however, they do perform glycolysis in the cytoplasm. Why do all cells need an energy source, and what would happen if glycolysis were blocked in a red blood cell?

What part of the mitochondria is most acidic?
In a rare inherited disorder, called Wilson’s disease, excessive amounts of copper accumulate in liver and brain tissue. A prominent symptom of the disease is the deposition of copper in greenishbrown layers surrounding the cornea, called Kayser–Fleischer rings. A defective ATP-dependent protein that transports copper across cell membranes causes Wilson’s disease. Apparently, the copper transport protein is required to incorporate copper into ceruloplasmin and to excrete excess copper. In addition to a diet low in copper, Wilson’s disease is treated with zinc sulfate and the chelating agent penicillamine (p. 148). Describe how these treatments work. [Hint: Metallothionein has a greater affinity for copper than for zinc.]
The cardiovascular, respiratory, and gastrointestinal systems all work together to ensure that cells of the human body are able to carry out vital reactions, including aerobic respiration and protein synthesis.
Question. Write a short account to explain how each of these three systems ensures that cells receive the required raw ingredients needed for such cellular reactions and how two of the systems contribute to the removal of the waste products created.
Completion Note: (All three systems must be considered, and should include specific detail such as the role of named enzymes in the gastrointestinal tract and named biomolecules transported to and from cells. It is also important to briefly outline why body cells need to carry out aerobic respiration and protein synthesis.)
