Carrier Produce Active Proteins Sodium Ions Epithelial Cells

Front The epithelial cells that line the small intestine are adapted for the absorption of glucose. Explain how. ( 6 marks)
Back 1. Microvilli; 
2. Large/increased surface area; 
3. Many mitochondria; 
4. (Mitochondria/respiration) produce ATP / release or provide energy (for active transport); 
5. Carrier proteins for active transport; 
6. Channel / carrier proteins for facilitated diffusion; 
7. Co-transport of sodium (ions) and glucose or symport / carrier protein for sodium (ions) and glucose; 
8. Membrane-bound enzymes digest disaccharides / produce glucose;
