Structure of hemoglobin and how does oxygen bind to it

1 answer:

3 0

Hemoglobin is a protein that exists in the red blood cells. Hemoglobin contains iron atoms in its chemical structure which are responsible for binding with oxygen or carbon dioxide. In its final structure, Hemoglobin contains 4 sites that can bind to oxygen. Despite that, it's difficult for a hemoglobin molecule to bind with four oxygen atoms at the same time because the structure will be complicated. Hemoglobin combined with oxygen is called oxyhemoglobin, while that combined to carbon dioxide is called carboxy hemoglobin.

Answer:

3/8

Explanation:

Martha has a widow's peak (dominant trait) and attached earlobes (recessive trait).

Martha's dad had a straight hairline (ww) and unattached earlobes (Ee, because she has the recessive alleles ee and both parents give us one allele).

This tells you that martha has a mother with at least one of both alleles dominant for widow peak and at least one recesive allele of attached earlobes

So, martha's alleles are: Ww and ee.

If she marries a man that is heterozygous for both traits (Ww and Ee) the probabilitys are

Ww Ee x Ww ee: WWEe, WwEe, wWee, and wwee

Carbon dioxide (chemical formula CO2) is a colorless and odorless gas that is vital to life on Earth. This naturally occurring chemical compound is made up of a carbon atom contently double bonded to two oxygen atoms. Carbon dioxide exists in Earth's atmosphere as a trace gas at a concentration of about 0.04 percent (400 ppm) by volume.Natural sources include volcanoes, hot springs and geysers, and it is freed from carbonate rocks by dissolution in water and acids. Because carbon dioxide is soluble in water, it occurs naturally in groundwater, rivers and lakes, in ice caps and glaciers and also in seawater. It is present in deposits of petroleum and natural gas.
