Disulfide bonds are involved in maintaining ________ protein structure as well as the ________ level of protein structure exhibi
Whitepunk [10]

Answer:

tertiary; quaternary

Explanation:

The orientation of all the atoms of a protein in three dimensions represents its tertiary structure. It includes the folding of the polypeptide chains in a way that brings are far apart amino acids of its secondary structure close together. Various segments of a polypeptide chain interact to form tertiary structures and these segments are held together by different kinds of weak interactions.

However, disulfide cross-links between the segments of polypeptide chains also stabilize the tertiary structure of some proteins. Likewise, disulfide bonds also hold the protein subunits of some proteins together and thereby, contribute to the quaternary structure. For example, two light chains of an antibody are joined together by disulfide bonds.

In hemoglobin, the transition from t state to r state (low to high affinity) is triggered by:_________
Elena L [17]

In hemoglobin, the transition from t state to r state (low to high affinity) is triggered by Bisphosphoglycerate (BPG)

  • Bisphosphoglycerate (BPG), also known as 2,3-Disphosphoglycerate (2,3-DPG), aids in the transition of hemoglobin from a high-oxygen-affinity to a low-oxygen-affinity state.
  • 2,3-BPG binds to hemoglobin, causing oxygen to be unloaded. Furthermore, 2,3-BPG reduces hemoglobin's affinity for oxygen. As hemoglobin is unloaded in our tissues, 2,3-BPG binds to it, promoting oxygen unloading.
  • When we increase the concentration of 2,3-BPG in our blood, the oxygen binding curve shifts to the right. This means hemoglobin will have a lower affinity for oxygen and will be able to deliver more oxygen to our body's tissues and cells.
