Biochemistry C785 Module 3 Myoglobin and Hemoglobin

Biochemistry C785 Module 3 Myoglobin and Hemoglobin What level of protein structure does hemoglobin have that is not found in myoglobin? 1. primary 2. secondary 3. tertiary 4. quaternary(C0rrect) As carbon monoxide binds to hemoglobin, the protein subunits change conformation to allow carbon monoxide to bind faster. This process is called __________. 1. non-competitive inhibition 2. allosteric binding 3. positive cooperativity(correct) 4. competitive inhibition 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(correct)
