Proteasas are enzymes that break down proteins. Gastric proteasas are found in the stomach; intestinal proteases are found in the small intestine. Estimate the optimum pH for these two enzymes and identify as acidic or basic: Gastric proteases: pH= ____; acidic or basic Intestinal proteases activity: pH= ____; acidic or basic
