Question

Distinguish between biological value and protein efficiency ratio.

Answer 1

Hey mate, here is your answer :

Protein efficiency ratio(PER) is based on the weight gain of a test subject divided by its intake of a particular food protein during the test period whereas biological value (BV) is a measure of the proportion of absorbed protein from a food which becomes incorporated into the proteinsof the organism's body. It captures how readily the digested protein can be used in proteinsynthesis in the cells of the organism. 

Hope this answer helps you...
