Both myoglobin and hemoglobin exhibit cooperative binding to oxygen. True or False
lys-0071 [83]

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.

A wildlife biologist is investigating a sudden increase in the death rate
Ann [662]

Answer:

circulatory and respiratory

Explanation:

The body system of Birds possesses a higher arrangement of organs to perform a particular function. The organs form a system which includes the organs and associated structures.

When the biologist observed the shortage of the dissolved oxygen and increase in the level of dissolved carbon dioxide, this could be the result of the failure of the circulatory system which supplies these gases on the body and the associated respiratory system which helps in the exchange of these gases with the atmosphere.

Thus, circulatory and respiratory is the correct answer.
