Heme is the iron-containing structure in the proteins hemoglobin and myoglobin. In red blood cells, hemoglobin enables oxygen uptake and transport. Myoglobin in muscle cells helps oxygen enter the cells. The oxygen carried by hemoglobin and myoglobin is critical for energy production. Because meat contains hemoglobin and myoglobin, beef, fish, and poultry contain more heme iron than most plant foods. The remaining iron in meat, as well as all the iron in vegetables, grains, dietary supplements, and fortified or enriched...

1. Describe using thermodynamics the enthalpic stabilizatiok of the T-state and whether high or low [O2] would be favored and why. 2. Predict the effect of red blood cells expressing (producing) myoglobin instead of hemoglobin. 3. List the interactions that stabilize the R-state (oxyhemoglobin), pick all that are correct. A) Numerous salt bridge interactions in the central cavity B) Coordinate covalent bonds (4) between O2 and heme C) H-bonding (4) between O2 and distal His 4. Where are the interactions...
Question 31 6 pts 16) Some patients with erythrocytosis (excess Red Blood Cells) have a mutation that converts a Lysine to Alanine at residue 82 in the beta-subunit of hemoglobin. This particular Lysine normally protrudes in the central cavity of deoxyhemoglobin, where it participates in binding 2,3,-bisphosphoglycerate (BPG). What effect would you predict this mutation will have on a) the affinity of hemoglobin for BPG and for b) the affinity of hemoglobin for Oxygen in patients with erythrocytosis? Briefly explain...

Multiple motor neurons and multiple muscle fibers A single motor neuron and multiple muscle fibers A single motor neuron and a single muscle fiber Multiple motor neurons and a single muscle fiber
Digestion contributes to homeostasis by Group of answer choices producing red blood cells to transport O2. providing cells with nutrient molecules that are needed to sustain life. providing hormones which regulate blood chemistry. filtering out nitrogenous wastes from the blood.
When there are too many red blood cells, is the bohr effect still observed?
Hemoglobin is the compound in red blood cells that carries oxygen to the body. The distribution of hemoglobin in women in g/dl of blood is approximately bell shaped with mean 14 and standard deviation 1. According to MedicineNet.com, healthy hemoglobin levels range from 12 to 16. Based on the Empirical Rule, what percent of women have healthy hemoglobin levels?
