Regarding the quaternary structure of human hemoglobin, it is in
C2 symmetry
D2 symmetry
C4 symmetry
D4 symmetry
Why is the term “hemolymph” more appropriate for invertebrates such as the crayfish, while the terms “blood” or “lymph” are more appropriate for mammals such as the pig?
In insects, as in some other animals we have seen, the hemocoel is
primarily responsible for:
providing a place for food storage
retracting the gubernaculum and the pharynx
O coeling the hemo
replacing the intestinal system with increased surface area
holding and circulating body fluids
protecting the anterior ganglia

- what does a hemoglobin concept map look like with 10 words or phrases?arrow_forwardWhich five statements about hemoglobin and myoglobin structure are true? Each iron atom can form six coordination bonds. Two of these bonds are formed between iron and oxygen. Molecular oxygen binds reversibly to Fe²+ in heme. Heme is composed of an organic protoporphyrin component and a metal atom. By itself, heme is not a good oxygen carrier. It must be part of a larger protein to prevent oxidation of the iron atom. Each hemoglobin or myoglobin molecule can bind four oxygen molecules. Hemoglobin is a heterotetramer, whereas myoglobin is a monomer. Both hemoglobin and myoglobin contain a prosthetic group called heme, which contains a central iron atom.arrow_forwardWhat color is deoxyhemoglobin? Why?arrow_forward
- Can someone explain this diagram? For example, it says here the pulmonary arteriole carries deoxygenated blood to the heart, but I thought arteries carry blood away from the heart?arrow_forwardWhy does Fe2+ not fit perfectly into the center hemoglobin's heme pocket, while Fe3+ does ift perfectly into center hemoglobin's heme pocket? A) Fe2+ has a larger effective nuclear charge than Fe3+ . B) Fe2+ is to reactive to stably fit into hemoglobin's heme pocket. C) Fe2+ had a wrinkled shirt D) Fe2+ is repelled by the heme's coordinating nitrogens E) Fe3+ is denser and has a smaller ionic radius than Fe2+arrow_forwardDraw diagram CHP systemarrow_forward

The number of high affinity binding sites in the R form of hemoglobin is .The number of low affinity binding sites in the R form of hemoglobin is .The number of O2 molecules that need to bind to convert hemoglobin from the T to R form is .The number of high affinity binding sites in the T form of hemoglobin is .The number of low affinity binding sites in the T form of hemoglobin isarrow_forwardWhat is the gene code for hemoglobin?arrow_forwardWhich of the following statements is correct of BOTH haemoglobin and myoglobin? Acidic conditions increase the affinity for oxygen. The iron atom of the heme prosthetic group is bound to nitrogen atoms at five of six coordination sites. Four oxygen molecules bind to each subunit. Quaternary structure is found in both haemoglobin and myoglobin. Both haemoglobin and myoglobin show the same oxygen binding affinity at differentarrow_forward
- Why is the binding of oxygen to hemoglobin cooperative while the binding of oxygen to myoglobin is not? A) Myoglobin has more x-helix than hemoglobin B) Hemoglobin has more iron (Fe) atoms C) Hemoglobin has more than one subunit D) Myoglobin is affected by changes in pHarrow_forwardWhat units describe Hemoglobin and in your own words describe what Hemoglobin is What units describe Hematocrit and in your own words describe what Hematocrit is Pick one condition that casues high or low hemoglobin and explain why it causes high or low condition Pick one condition that casues high or low hematocrit and explain why it causes high or low conditionarrow_forwardWhat is the major element found in hemoglobin that allows it to do its job?arrow_forward
