A drop in pH would make protonation more likely, and a protonated proximal histidine would not be able to donate its electron density to the iron atom.
<h3>
What is the role of proximal histidine in hemoglobin?</h3>
The first histidine that is bonded to Fe(2+) we call proximal, and the histidine that bonds last, to the oxygen, we call distal.
Histidine is an amino acid most people get from food. It's used in growth, repair of damaged tissues, and making blood cells.
It helps protect nerve cells. It's used by the body to make histamine.
In hemoglobin, the role of proximal histidine is to hold the heme group in the correct location on the hemoglobin chain.
The proximal histidine also pulls the iron in heme out of the plane of the heme molecule. This iron will be pulled back into the plane when it is oxygenated.
The proximal histidine strengthens the iron-imidazole bond and helps to stabilize the oxidoreductase in its higher oxidation (i.e. compounds I and II) states.

Answer:
False.
Explanation:
The people in the bureaucracy are doing specialized tasks that demand training and competency. Only people specialized for their jobs can have the job done professionally.
The cons of specialization are that the bureaucrats can't work out of their field of specialization. The structure of the bureaucracy is called hierarchy, which goes from the menial worker to the highest executive body. People in every level of specialization have their jurisdiction and responsibility.
The correct answer is foot-in-the-door phenomenon.
This means that if a person agrees to comply with a small favor, they are likely to do something more as well. So, these people will listen to the telemarketers' pitches, which means that they might even buy the product afterwards.
Answer:
Individualism is lost
Explanation:
During an organized crowd it is usually found that individuals are less likely to respond as single individuals and they are more likely to move as a crowd. In these instances. The pressure of whatever moral standing or belief that they hold are lost to the movement of the crowd. These persons ignore their own feelings in the process.
Other theories of collective behaviour is the mob, crowd and riot theory. All these categories are justified in their own right to explain the mechanisms of the organization, execution and dissolution of these individuals.
