| Abstract: | NADPH-cytochrome-c-reductase from guts of gypsy moth, Porthetria dispar, oxidized NADPH at the following rates: 11·6, 41·9, and 57·6 nmol/30 min per 0·6 mg protein, in the third, fourth and fifth instar, respectively. The increase in specific activity may be due to a natural induction process controlled by materials in the food. This could also explain the observed decreases just prior to ecdysis at which time the larvae have ceased feeding. |
