Answer: The more active cells produce more carbon dioxide.
Explanation:
When the cells are constantly working the amount of oxygen consumed and more amount of carbon dioxide is released by the cells.
Chemo receptors in the circulatory system increases the ventilation so that more carbon dioxide can go out of the cell and more oxygen can get inside the cell.
This is because the more active cells more carbon dioxide and there is a sudden increase in the concentration of carbon dioxide which need to be corrected by the help of ventilation.
Answer: Coenzymes
Explanation:
Coenzymes are the small organic molecules that are often derived from the vitamins. It can be tightly or loosely bond to the enzymes.
Tighly bond ones are the prothestic groups and loosely bond ones are coenzymes like the products and substrate which binds to the enzyme and get released from it.
This component is very important for any reaction to take place. It bonds to the enzymes and helps in product formation.
