Answer:
Low phenylalanine concentration:
- If the enzyme is inactive, PAH will look like its inactive form, with phenylalanine located in the allosteric site / inactive site so that PAH is a different shape. This will not allow as much phenylalanine to be converted into tyrosine, as we wait for Phe levels to increase.
High phenylalanine concentration:
- If the enzyme is active, PAH will look like its regular form, with an open active site that's the size of phenylalanine so that reactions can occur. (Like a hand fitting into a glove, or a lock into a key.) Phenylalanine will be the substrate, the thing acted upon by the enzyme. This will eventually raise the amount of tyrosine that's created and lower the concentration of phenylalanine.
Think about it like this. Ever heard of homeostasis? That's how the body likes to be the same, keep everything regulated, all the time. So if there are high levels of something, the body is going to try to keep that something down, and if there are low levels, it's going to try to increase the concentration of that thing.

Answer:
The correct answer is - molars.
Explanation:
Mechanical digestion takes place inside the mouth of an organism by the process called masticating with the help of teeth. There are four types of teeth in the mouth all help in the digestion of the feed incisor cuts the food, canines tear the food, premolars, and molars chew or masticate the food.
The main and major tooth that helps in mechanical digestion is the molar to chew food so it can mix with the saliva to make bolus and chemical digestion.
