✦ Synopsis
The specific and total activities of acid phosphatase (AcP), hyaluronidase (HU), P-N-acetylglucosaminidase (NAG) and lactate dehydrogenase (LDH) of tail fin are constant during prometamorphosis. During climax, as the fin is resorbed, the activities of the hydrolases increase while the specific activity of LDH remains constant and the total activity decreases. The apparent K m and pH optimum of the hydrolases are the same at prometamorphosis and climax. Similar changes in enzyme activities are found in pieces of pro-
