What is the difference between the ""one gene-one protein"" and ""one gene-one polypeptide"" hypotheses?

"One gene-one protein" hypothesis states that one gene codes for one protein while the "one gene-one polypeptide" hypothesis states that one gene codes for one polypeptide chain of a protein having more than one type of polypeptide chains.

Explanation:

Beadle and Tatum proposed the one gene-one protein concept to explain the one-to-one correspondence between genes and proteins. Accordingly, one gene carries information to encode one protein. Since enzymes are proteins with catalytic power, a gene encodes the information to produce a single enzyme.

The "one gene-one protein" concept was later modified into the "one gene-one polypeptide" hypothesis. According to the "one gene-one polypeptide" hypothesis, one protein may have more than one polypeptide chain. One gene carries the genetic information to encode one polypeptide. Therefore, a protein with more than one type of polypeptide chains will be encoded by more than one gene.

the answer is lactic acid from anaerobic respiration. the acid in lactic acid is what creates sore and burning muscles. if you think about how acid burns that will give you a clue for questions like this.
