Compare the structure of the chlorophyll molecule to the structure of the protoporphrin component of hemoglobin.
Compare the structure of the chlorophyll molecule to the structure of the protoporphrin component of hemoglobin.
Describe the differences and similarities between hemoglobin and chlorophyll and their medical implication
Myoglobin and the individual subunits of hemoglobin are polypeptides of similar size and structure. Compare the expected ratio of non-polar to polar residues in myoglobin and hemoglobin. Provide a detailed rationale for your answer
Which five statements about hemoglobin and myoglobin structure are true? Both hemoglobin and myoglobin contain a prosthetic group called heme, which contains a central iron atom. Each iron atom can form six coordination bonds. One of these bonds is formed between iron and oxygen. 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....
Match the best answer with the option that fits it. Component of chlorophyll magnesium Component of all proteins potassium Uniform chlorosis of leaves, necrosis, stunting nitrogen Purplish color with purple veins in leaves phosphorus Very mobile potassium
1. Compare and contrast the structure and function of myoglobin to hemoglobin. Provide detailed information & figures on the primary, secondary, tertiary & quarternary structures pf these proteins, and how these structures reate to function. 2. Provide a detailed drawing (with figures) of the prosthetic group Heme and a detailed explanation of its role in myoglobin amd hemoglobin function. 3. Provide a detailed drawing (with figures) of the cooperative binding of oxygen by hemoglobin. 4. Provide a detailed drawing (with...
20. The following statements compare the differences between the chlorophylla molecule at the center of a photosystem and chlorophyll elsewhere in the photosystem which statement is false? The excited electrons in chlorophyll that are not at the photosystem center return to their resting state, whereas the excited electrons in reaction center chlorophyll a are transferred to the primary electron acceptor Chlorophylla at the photosystem center has one more electron in its chemical structure than the chlorophy molecules have elsewhere in...
We discussed the relationship between the structure of hemoglobin and its function. Briefly discuss how the structure of hemoglobin make it a much better oxygen transport and delivery molecule than myoglobin.
Which 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. Each hemoglobin or myoglobin molecule can bind four oxygen molecules. Heme is composed of an organic protoporphyrin component and a metal atom. Hemoglobin is a heterotetramer, whereas myoglobin is a monomer. By itself, heme is not a good oxygen carrier. It must be part of a larger protein to prevent oxidation of...
1A- What happens whej light "excites" an electron of a chlorophyll molecule? A- The electron moves to an electron shell that is further from the nucleus B- Nothing. Light does not have this effect on electrons C- The electron moves to an electron shell that is closer to the nucleus D- An electron is transferred to another molecule 1B- What molecule is oxidized in order to reduce the special chlorophyll a pair? A-Water B-Glucose C- None. The special chlorophyll pair...
A hemoglobin molecule can carry one oxygen or one carbon monoxide molecule. Suppose that the two types of gases arrive at rates 1 and 2 and attach for an exponential amount of time with rates 3 and 4, respectively. Formulate a Markov chain model with state space {+, 0, −} where + denotes an attached oxygen molecule, − an attached carbon monoxide molecule, and 0 a free hemoglobin molecule and find the long-run fraction of time the hemoglobin molecule is...
