Final answer:

Gas exchange in the respiratory system occurs in the alveoli.

Explanation:

Gas exchange in the respiratory system primarily takes place in tiny, balloon-like structures called alveoli. These are found in the lungs and are surrounded by an extensive network of blood vessels. During inhalation, oxygen-rich air enters the alveoli, diffusing through their thin walls into adjacent capillaries.

Simultaneously, carbon dioxide, a waste product of cellular respiration, diffuses from the bloodstream into the alveoli to be exhaled during exhalation. This exchange of oxygen for carbon dioxide is vital for cellular function and provides the body with the oxygen needed for energy production, while also removing waste carbon dioxide to maintain proper pH levels in the blood.

Answer:

Cytochrome C; it provides evidences that there is similarities in the respiratory pathways for producing ATPs by  all living organisms especially mammals.

Explanation:

Cytochrome c is located in the intermembranes of mitochondria, and it functions in the transfer of  of one electron in electron transport chain,(ETC) needed for  generation of proton motive force;  for generation of energy in the synthesis of ATPs by ATPase synthase  during chemiosmosis. Its allows oxdation-reduction by the switching of its iron ii to iron iii. during electron transports.However its iron atoms does not undergo oxidation with  oxygen. This feature makes it stable and  an ideal carrier of electrons.

Its amino acid sequences is very similar in all living organisms especially  between mammals(e.g man and chimpanzees)with little variation in few amino acid residues due to mutation.This similarity in its amino acids sequences in all  living  organism together with small molecular size makes it ideal  molecular evidence  for studying comparative molecular evidence of  evolution.

This is because it can be used  to trace  the pathways of respiration to synthesize energy, and therefore to conclude that  most  organisms share common ancestry, since a very similar protein sequence in  a structure(Cytochrome c) participated in unique ETC mechanisms  in all, needed for energy synthesis .
