Question: Which is the first enzyme to mix with food in the digestive tract?
A Pepsin
B Cellulase
C Amylase
D Trypsin
Answer: Amylase
| Name of enzyme | Location in digestive tract | Function |
| Salivary amylase | Mouth | Salivary amylase is the first enzyme to begin the digestion of starches and complex carbohydrates in the oral cavity. |
| Pepsin | Stomach | This enzyme actively breaks down proteins into smaller peptides. |
| Gastric lipase | Stomach | Gastric lipase digests some fats in the stomach. |
| Pancreatic amylase | Small Intestine | Continues the digestion of carbohydrates into simpler sugars. |
| Trypsin | Small Intestine | Breaks down proteins into peptides. |
| Chymotrypsin | Small Intestine | Further digests proteins into peptides. |
| Pancreatic lipase | Small Intestine | Digests fats into fatty acids and glycerol. |
| Lactase | Small Intestine | Breaks down lactose (milk sugar) into glucose and galactose. |
| Maltase | Small Intestine | Breaks down maltose (a type of sugar) into glucose. |
| Sucrase | Small Intestine | Digests sucrose (table sugar) into glucose and fructose. |
| Peptidases | Small Intestine | Break down peptides into amino acids. |
