Consider hemoglobin’s protein structure to answer A-C below (16 pts total). When typing your answers, be sure to label them as A, B, and C so I know your designated answers. A. How many subunits does hemoglobin contain and what are they individually called/named? (5pt) B. What do the T and R states of hemoglobin represent (what do T and R stand for?) and how do they differ in affinity for oxygen? (3pts) C. The binding and release of oxygen in hemoglobin requires transitions between the T and R state (especially between the lungs vs active tissues). There is one major structural process by which this transition occurs which can be achieved by at least 5 specific ways that cause the protein conformational change to be triggered. Describe the major structural process that causes the transition between T and R conformational states and then list 3 possible examples/ways this is achieved AND explain how each works to allow effective transport of oxygen (8pts). Please use my template below when typing your answer (copy below and fill in your answers after the colons) Major Structural Process:  I. Specific Example 1: How it works:   II. Specific Example 2: How it works:   III. Specific Example 3: How it works:
