An interesting enzyme, whose molecular weight is 56,000 g/mol, is used in catalytic amounts to cleave a membrane protein, whose molecular weight is 65,000 g/mol, into two fragments having molecular weights of 43,000 and 22,000 g/mol. Gel chromatography is used to assess the extent of reaction at various times. Three major fractions of proteins are eluted at each time. What are they and in what order are they eluted
