Answer:
Average annual temperature in US cities would range between 50-70 degrees Fahrenheit
Explanation:
There are several factors that can influence the temperature of city in general. Higher altitude has a lower temperature because it has less air density and absorbs less sunlight. The city latitude coordinate also determines how much sunlight they will get. The closer the city to the equator, the more sunlight they can get.
Distance to the sea will influence the rate of rainfall and also influence temperature. Ocean currents can move hot water from other regions too.
The proteins(particularly enzymes) of the membrane help chemical reactions.
An example would be enzymes involved in electron transport chain.
The binding of sugars are called glycosidic bonds. These bonds are covalent bonds which, by definition, surround the anomeric carbon of a monosaccharide. Contrary to popular belief, the glycosidic bond does not necessarily have to be between two monosaccharides, just think about what happens in nucleotides, for example, where ribose establishes a glycosidic bond with the nitrogen base. Of course, it can also involve two monosaccharides, as is the case with bonds in oligosaccharides or polysaccharides, but this is not required to happen.
When a glycosidic bond is established, a water molecule is released and is therefore a condensation reaction. The oxygen atom and one hydrogen are released from the anomeric carbon, while the second hydrogen atom is released from the atom to which the anomeric carbon will bind.
Glycosidic bonds are also called alpha or beta bonds. This nomenclature depends on the configuration of the anomeric carbon involved in the glycosidic bond. That is, if the anomeric carbon is in the alpha configuration, the bond is of the alpha type, if it is in the beta configuration, the bond is of the beta type.
