Structure of hemoglobin and how does oxygen bind to it

Biology
1 answer:
vivado [14]3 years ago
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.

What is the name of the enzyme used to make rna nucleotides
Likurg_2 [28]
<h2>RNA Polymerase</h2>

Explanation:

  • RNA polymerase, a chemical in the cell, is  answerable for making mRNA from the  right quality. RNA polymerase is like  DNA polymerase, yet it makes a RNA strand  as opposed to a DNA strand. The promoter region of DNA Helix is attached by  RNA polymerase.
  • It pulls in nucleotides that supplement those  on the DNA strand containing the gene of interest. RNA polymerase duplicates one strand of  DNA to make a stretching bit of singlestranded  mRNA. RNA polymerase makes the  mRNA strand in what is known as the 5' to 3'  course.

The answer is Mullerian mimicry.

Mullerian mimicry is a kind of mimicry in which two or more poisonous animals generate identical presences as a shared protective tool. The theory behind this is that if a predator learns to avoid one of the poisonous species, it will also avoid the mimic species as well.

It is a natural process in which two or more often repugnant species, which may or may not be closely associated and share one or more common predators, have started to mimic each other's cautionary signals, for their communal benefit, as predators eventually learn to avoid all of them.
