Study Notes
Carbohydrates and Energy
- The primary source of carbohydrates for plants is sunlight, which is converted into chemical energy through photosynthesis.
Carbohydrate Breakdown
- Animals and fungi break down stored carbohydrates into energy through cellular respiration, a process that releases energy from glucose molecules.
Glucose Transformation
- Non-glucose monosaccharides are transformed into glucose after resorption in the small intestine, specifically in the epithelial cells lining the intestinal wall.
Digestion of Complex Carbohydrates
- Complex carbohydrates are broken down into simple monomers, including glucose, fructose, and galactose, during digestion.
Cellular Respiration
- The end products of cellular (aerobic) respiration of glucose and oxygen are carbon dioxide, water, and ATP (energy), which is then used to power cellular activities.
