AP Bio FRQs Latest Version 2024/2025 Graded A+ Based on the model, explain whether the molecules shown crossing the membrane require energy to do so. The response indicates that energy is not required for the substances to cross the membrane because the substances are being passively transported from a region of higher concentration to a region of lower concentration. Depending on the organism, the optimal pH for enolase to catalyze its reaction is between 6.5 and 8.0. Describe how ...
