The shape of proteins are affected by temperature and pH.
The change of shape of proteins is known as denaturation.
Denaturation of a protein will make it unable to function.
<h3>What factors affect protein functions?</h3>
Proteins are large molecules which are found in living organisms.
The shape of proteins are affected by temperature and pH of their environment.
The change of shape of proteins is known as denaturation.
Denaturation of a protein will make it unable to function since protein function depends on its shape.
In conclusion, protein denaturation affects its function.

Answer: False.
Meat is a good source of protein. There are nine essential amino acids which are required under special conditions like illness.
These are- Histidine, Leucine, Isoleucine, Valine, Threonine, Methionine, Lysine, Phenylalanine and Tryptophan. They cannot be synthesized by the body and therefore need to be taken from external protein sources.
Since meat contains all the essential amino acids, therefore it is considered as a good source of protein. Hence, the given statement is false.
