The oesophagus helps with digestion rather than respiration as it is connected from mouth to stomach.
Respiratory system is defined as the system that performs the function of gaseous exchange.During this process fresh air is inhaled and waste material in form of carbon dioxide is released out.
The main components of respiratory system are lungs, blood vessels, trachea and nassal passage. By combining all these components respiratory system of the body performs it's function properly.
The body consists heart, blood vessels, arteries, veins and blood that all combined together to supply blood to all parts of body and takes up waste material from it and four major components and these are heart, veins, arteries, and blood.

Therefore,the oesophagus helps with digestion rather than respiration as it is connected from mouth to stomach.

B)It is the final acceptor for electrons in the electron transport chain.
C)The chemical bonds within its carbon skeleton can be used to produce ATP.
D)Its coenzyme form assists in breakdown of carbohydrates, fats, and proteins.
Thiamin (or thiamine) is one of the water-soluble B vitamins. It is also called Vitamin B1. Thiamin acts like a cofactor in the body by helping the body's cells to change carbohydrates into energy. Thiamin acts as a coenzyme in the metabolism of branch-chain amino acids.
The following best describes the role of thiamin in energy metabolism: Its coenzyme form assists in breakdown of carbohydrates, fats, and proteins. Correct answer: D The coenzyme which is essential for energy metabolism is Thiamin pyrophosphate (TPP).
