25. What level of protein structure does hemoglobin have that is not found in myoglobin? 1. primary 2. secondary 3. tertiary 4. quaternary 10. 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 differs when comparing myoglobin to hemoglobin? 1. Primary 2. Secondary 3. Tertiary 4. Quaternary 43. As carbon monoxide binds to hemoglobin, the protein subunits change conformation to allow carbon monoxide to bind faster. This process is called __________. 1. non­competitive inhibition 2. allosteric binding 3. positive cooperativity 4. competitive inhibition 1. Which of the following accurately describes the functions of hemoglobin and myoglobin? 1. Hemoglobin transports oxygen, Myoglobin stores oxygen. 2. Hemoglobin stores oxygen, Myoglobin transports oxygen. 3. Hemoglobin transports CO2 and Myoglobin stores CO2 4. Myoglobin transports CO2 and Hemoglobin stores CO2 7. Hemoglobin and myoglobin proteins bind molecular oxygen. The protein subunit of hemoglobin does not bind directly to the oxygen. Instead, a specific atom binds oxygen. In hemoglobin, which of the following will directly bind oxygen? 1. Histidine 2. Heme 3. Carbon Monoxide 4. Iron
