What process takes place at the boundary between the capillaries and the alveoli?
Schach [20]

Answer:

Carbon dioxide enters the alveoli, and oxygen enters the capillaries.

Explanation:

This describes the exchange of gases in the lungs. When blood from the rest of the body gets to the lungs through the capillaries, oxygen flows from the alveoli which are tiny air sacs in the lungs, into the blood in the capillaries.

Carbon dioxide from the blood brought to the lungs will then flow into the alveoli which will then expel it through the nose. This repeated process ensures that the body keeps getting oxygen and expelling carbon dioxide.

valentina_108 [34]

Answer:

Having a repetitive enzyme system would allow more than one enzyme to catalyze a particular reaction. If one of the types of enzyme is not able to perform its function due to temperature or any other factor, then another kind of enzyme would be able to catalyze the reaction. Hence, having repetitive enzyme systems is very effective in carrying out the metabolic functions of the body even when conditions are not favourable.
