Digestive Enzymes and Locations
Ever wondered where your body produces the enzymes that break down your food? This question tests your knowledge of enzyme production in different digestive organs.
Amylase is produced by the pancreas and salivary glands - it's the enzyme that starts breaking down starch in your mouth and continues the job in your small intestine. Maltase, however, is produced by the small intestine itself, specifically in the brush border of intestinal cells.
The key concept here is enzyme specificity - maltase only catalyses the hydrolysis of maltose because enzymes have a specific active site shape. Think of it like a lock and key - maltase's active site perfectly complements maltose's shape, but won't fit other substrates.
Quick Tip: Remember that enzyme specificity comes from the unique 3D shape of the active site, which is determined by the enzyme's tertiary structure.
