Hemoglobin (Hb) is the O2-carrying protein in our blood. Unlike myoglobin, it has four sites allowing it to bind up to four O2 m

olecules. Additionally, the tendency of O2 to bind to each site increases as the other three sites become occupied (this is an example of a phenomenon known as positive cooperativity). To model this effect, consider a simplified hemoglobin-like protein with two binding sites. When no sites are occupied, the system energy is 0; when only one of the two sites is occupied, the energy is E; and when both sites are occupied, the energy is 2E J. Here J parameterizes the cooperativity, as when both sites are occupied, the energy is not simply the sum of the individual binding energies at each site.

Answer:

Yes, the energy is not simply the sum of the individual binding energies at each site, it is the product of energy at each binding site of hemoglobin.

Explanation:

Myoglobin and hemoglobin are two different cells. Myoglobin binds only one oxygen while the hemoglobin has the ability to binds four oxygen atoms at its four sides. Myoglobin present in muscle tissue only while hemoglobin is present in the whole body. Oxyhemoglobin is formed when oxygen binds with hemoglobin cell. This oxygen is take to all cells and energy is released due to the breakdown of glucose molecules with this oxygen.

(Fill the blank)<br> the ________ g____ makes saliva that make your food wet and easy to swallow
blagie [28]

Answer:

What make saliva that make your food wet and easy to swallow?

enzyme amylase

Explanation:

The digestive functions of saliva include moistening food, and helping to create a food bolus, so it can be swallowed easily. Saliva contains the enzyme amylase that breaks some starches down into maltose and dextrin. Thus, digestion of food occurs within the mouth, even before food reaches the stomach.

o-na [289]

Answer:

Most of UV radiation is stopped by glass & this is why you will not get sunburns behind a glass. The glass simply filters out the UV radiation that is responsible for the sunburns & protect your skins from these energetic & somewhat harmful radiation

How to calculate the number of protons and neutrons in elements
Nuetrik [128]
The atomic number is the number of protons. So, you can subtract the atomic number from the mass number to find the number of neutrons.
I hope this helps! :)
