myoglobin correct answers only has one peptide subunit and is located in muscle, draws in oxygen from the blood stream by having a higher affinity for it than hemoglobin to pull in oxygen from the mother's circulatory system correct answers Why does fetal hemoglobin have a higher affinity than mother hemoglobin? partial pressure of oxygen is lower at higher altitudes, requiring a higher affinity to pull in sufficient oxygen correct answers Why do animals that live at higher altitudes such...

ACS BIOCHEMISTRY EXAM WITH LATEST QUESTIONS AND ANSWERS___ well updated ß-turns (Correct Answer) - Tight u-turns with specific phi-psi angles. Must have gly at position 3. Proline may also be at ß-turn because it can have a cis-omega angle. Loops (Correct Answer) - Not highly structured. Not necessary highly flexible, but can occasionally move. Very variable in sequence. Circular Dichroism (Correct Answer) - Uses UV light to measure 2° structure. Can be used to measure destabili...

Oxygen Transport and Binding in Hemoglobin and Myoglobin Questions And Answers A+ Graded Homologous heme proteins - ANS-Hemoglobin and myoglobin Hemoglobin function - ANS-Transport oxygen in the blood from the lungs and collect CO2 from the cells Myoglobin function - ANS-In muscle cells, accepts, stores, transports, and releases oxygen Saturation - ANS-Myoglobin has a hyperbolic saturation, while hemoglobin is sigmoidal due to positive cooperativity Oxygen Affinity - ANS-Deoxyhem...

Mod7,8, Medical Biochemistry Unit 1 Exam, Week 2 Evaluation, Pre-Evaluation Question Bank 1with Verified Answers| 100% Correct| 100% Score Succinate is a substrate for which complex in the ETC? - Complex II In the case of an exothermic reaction: - deltaG0 (spontaneous reaction) would be negative Last cytochrome in ETC, cytochrome oxidase, passes electrons to O2. Cytochrome oxidase is able to do this because it has: - lower Km for oxygen then hemoglobin The lower Km for oxygen allows cytoc...
