Study Notes
Metabolic Pathways
- Metabolic pathways are a series of reactions converting substrates to products.
- Enzymes catalyze these reactions.
- Pathways are categorized as anabolic (synthesis) or catabolic (degradation).
- Intermediates link metabolic pathways.
- Metabolism encompasses all synthesis and breakdown pathways.
Cellular Chemical Energy
- Cells store energy in reducing potential and high-energy covalent bonds.
Carbohydrates
- Carbohydrates contain many hydroxyl (-OH) groups.
- Glucose is the most common carbohydrate.
- They are used for energy metabolism and biosynthesis of other carbohydrates.
Monosaccharides
- Monosaccharides are used for energy and biosynthesis.
- Small monosaccharides have 3-7 carbons, 6 being the most common.
Complex Carbohydrates (Polysaccharides)
- Polysaccharides are used for energy storage (starch, glycogen) and structural components (chitin, cellulose).
- Starch is a combination of amylose and amylopectin.
Glycogen Metabolism
- Glycogen is the primary carbohydrate storage form in animals.
- Glycogen synthesis is known as glycogenesis.
- Glycogen degradation is called glycogenolysis.
- Glycogen synthase and glycogen phosphorylase are key reciprocal regulatory enzymes.
