Study Notes
Carbohydrate Digestion and Absorption
- The stomach is responsible for the inactivation of salivary amylase during carbohydrate digestion.
- Fiber is the type of carbohydrate that is not digested in the small intestine.
- Enzymes such as maltase, sucrase, and lactase are responsible for digesting maltose, sucrose, and lactose in the small intestine.
Carbohydrate Absorption
- The GLUT5 transporter is responsible for the absorption of fructose in the small intestine.
- The rate of absorption of carbohydrates is impacted by factors such as surface area, concentration gradient, and blood flow.
Cellular Transport
- The liver is the organ that surrounds a substance, forming a vesicle during active transport.
- Facilitated diffusion is the type of transport that occurs down its concentration gradient, facilitated by a membrane-bound transport protein.
- Osmosis is the type of transport that involves the movement of water.
Additional Facts
- The mouth is the organ responsible for the digestion of carbohydrates using salivary amylase.
- Pepsin is the enzyme that inactivates salivary amylase during carbohydrate digestion.
- Fiber is a type of carbohydrate that delays gastric emptying.
- The SGLT1 and GLUT2 transporters are responsible for the absorption of all three monosaccharides in the small intestine.
- Chapter 4 in the book 'Nutrition and Metabolism' discusses carbohydrate digestion and absorption.
