Answer
b. Regulate the diet of the affected persons to severely limit the uptake of the amino acid.
Explanation:
<u>This is the effective way of managing PKU, if diet is not regulated, the blood plasma Phenylketonuria levels continue to build up from usual protein consumption. This leads to toxicity of the brain and brain dysfunctions. Nausea constipation, fatigues, health headaches are some of the results of the build up</u>.
Therefore to reduce the blood build up of phenylalanine and thus PKU; Special diet formulas rich in essential amino acids, and other needed nutrients which may be absent in phenylalanine low diet should be adopted. Amino acids substitutes notably Tyrosine which is lacking from failure of phenyalanine breakdown in phenylketouria is heavily supplemented. Tyrosine is important in brain function for alertness, focus,nervous communication.
The adoption of protein substitutes diet or regulated amino acid diet is very important because , all the needed amino acid are available , thus protein catabolisms which may trigger phenylalanine build up from muscles and liver storage withdrawal is prevented thus stabilizing its blood concentration.

This process is a technique of osmosis. Osmosis is the movement of solvent particles. For example, water along its concentration gradient, from high to low concentration, via a semi-permeable membrane is changing the structure of the molecules in the potato strips.
Since the environment of the potato strips are in a sugar concentrate, the potato will lose its water content and so loses weight and the strips will be thinner and dryer.
