WGU C624 Biochemistry Module 3, Exam Questions and answers, 100% Accurate. VERIFIED. Describe the functions of hemoglobin and myoglobin. - -Hemoglobin transports oxygen, Myoglobin stores oxygen. The correct number of subunits, heme groups, iron and oxygen that bind to hemoglobin versus myoglobin. - -Hemoglobin has: 4 subunits 4 heme groups 4 iron molecules binds 4 molecules of oxygen. Myoglobin has: 1 subunit 1 heme group 1 iron molecule binds 1 molecule of oxygen. Cooperativity - -Hemoglobin can bind subsequent molecules of oxygen more easily after the first oxygen molecule binds. Which statement about hemoglobin binding to carbon monoxide (CO) is true? - -Hb binds to CO with a higher affinity than oxygen and stabilizes the R-state. Carbon monoxide is poisonous because - -it binds hemoglobin 200 times better than oxygen. 2,3 BPG stabilizes the _____ state(s) of hemoglobin. - -T state Even though the amino acid sequence between subunits of hemoglobin and myoglobin are not exactly the same, there are other similarities between the two proteins. Which level of protein structure is not found in both molecules? - -Quaternary In the deoxygenated state the Heme is ____________, where as in the oxygenated state, the heme is _____________________. - -bent (non-planar), planar Fetal hemoglobin __________ - -binds to oxygen tightly at lower oxygen concentrations since its Rstate is the preferred structur
