Both myoglobin and hemoglobin exhibit cooperative binding to oxygen. True or False

Biology
1 answer:
lys-0071 [83]2 years ago
6 0

Answer:

False.

Explanation:

An Haemoglobin molecule  is made up of 4-polypeptides, with each of the polypeptide chain containing an haem group. These haem group can bind with one oxygen atom each.

T<u>he binding of the first oxygen atom  by the first haem group weakens the tertiary protein   structure  of  Quaternary structure  Hb, thus it makes it easier for the second Oxygen atom to bind faster, and the 3rd oxygen very fast and the 4th oxygen atom the fastest.These accelerated binding of the oxygen atoms, facilitated by the first binding O2, is called cooperative binding.It aids oxygen binding capacity and tranport functions  of Hb,</u>

<u />

<u>Myoglobin is an oxygen storage protein in  muscles, and not oxygen carrying molecule, It releases  stored O2 only in condition of low oxygen supply</u>.It has   one haem group in its molecule.Therefore its structural features can  not  carry out  cooperative binding.

Cells with 2 copies of each chromosome are called ______________, whereas cells with 1 copy of each chromosome are called ______
mojhsa [17]

Answer:

Cells with 2 copies of each chromosome are called <u><em>diploid</em></u>, whereas cells with 1 copy of each chromosome are called <u><em>haploid</em></u>.

Explanation:

Cells which comprise of homologous pairs of chromosomes are known as haploid cells. For example, the autosomal cells in humans contain 23 pairs i.e 46 chromosomes in them.

Cells which have only one copy of the chromosome are termed as haploid cells. For example, the sex cells of the humans i.e egg cell and sperm cells comprise of 23 chromosomes. This is half the number of chromosomes than the autosomal cells.

What are the characteristics of prokaryotes?
kherson [118]
Prokaryotes lack an organized nucleus and other membrane-bound organelles, the prokaryotic DNA is found in the central part of the cell called the nucleons, the cell size ranges from 0.1 to 5.0 in diameter, the cell wall of a prokaryote acts as an extra layer of protection, helps maintain cell shoe and prevents dehydration.
