Question
Hemoglobin in red bloodcells binds much more closely to CO than it does to oxygen.Hemoglobin’s ability to transport oxygen is severelycompromised in the presence of CO.
a. A malfunctioningfurnace is one potential cause for CO poisoning. What are someother situations in which you could be exposed to carbonmonoxide?
b. Oxygen is necessaryfor cellular metabolism. What is the molecule that serves as thesource of cellular energy?
c. If cells are deprivedof oxygen, what is the effect on the production of cellular energy?Be specific
2. There are threespecific nutrients that are necessary for the body to form redblood cells.
a. Can you name allthree?
b. What are good foodsources for these nutrients?
3. What type of organicmolecule is hemoglobin? What nutrient is required to formhemoglobin?
4. The hormoneerythropoietin is produced by the kidneys whenever more red bloodare necessary. Think of several reasons when the body will needmore red blood cells.
Explanation / Answer
1. a. Car exhaust as a result of the combustion of gasoline is asource of CO. b. This would be the molecule ATP- Adensosine tri-phosphate.This is produced during the KREBS cycle and the electron transportchain and oxidative phosphorylation in the mitochondria. c. oxygen allows the electron transport chain and oxidativephosphorylation to occur. This produces 34ATP molecules incomparison to glycolysis which does not need O2 and prodcues 2ATP. 3. a. Hemoglobin is a quaternary form of 4 polypeptide chains.Iron is an essential element of hemoglobin. 4. More red blood cells would be needed in the case of thefollowing: a. Regular aerobic exercise would cause the body to need moreoxygen on a regular basis and the body would respond by increasingRBC count. b. Living at increased elevation where the concentration of O2in the air is lower would result in a need for more RBCs. c. Loss of blood or donation of blood would cause a need formore RBCs to be produced. I hope that these answer some of the questions. 3. a.
