The main function of the respiratory system is to allow the exchange of gases between the atmosphere and the lungs.
Hence,the only structure that carries out this function is the alveoli as other structures such as the nose,trachea and pharynx transport gases to the alveoli just so that it can can out its function.
Answer:
They are called psycrophiles or cryophiles.
Enzymes can be denatured unfolded by heat or chemicals.
<h3>What are enzymes?</h3>
Enzymes are proteins that are found in living organisms which are able to increase the rate of chemical reaction and remains unchanged at the end of the reaction.
The factors that can denature enzymes include heat and chemicals. This is because:
- Higher temperatures disrupt the shape of the active site, which will reduce its activity, or prevent it from working. When the enzyme loses its shape, it is said to have been denatured.
- These environmental factors can alter the pH level of the enzyme.
Therefore, for an enzyme to perform its functions, the external factors that affects it's activities must be normal and favorable.
