Study Notes
Energy Sources and Metabolism
- Glucose is the preferred source of energy for the body.
- Autotrophs are organisms that can make energy-containing organic molecules from inorganic raw materials.
- Heterotrophs are unable to make energy-containing organic molecules from inorganic raw materials.
ATP and Bioenergetics
- ATP (Adenosine Triphosphate) plays a crucial role in biologic systems as the energy currency.
- The primary role of Bioenergetics is to study the flow of energy through living systems.
- ATP is the primary energy source for cellular processes in mitochondria.
Carbohydrate Structure and Digestion
- The empirical formula for carbohydrates like glucose is C6H12O6.
- Monosaccharides are connected to form larger carbohydrate structures through glycosidic bonds.
- Amylase is the enzyme responsible for the digestion of major dietary polysaccharides in the mouth.
- Glucose and galactose are absorbed in the small intestine through facilitated diffusion.
Sugar Chemistry
- Sucrose is formed through a condensation reaction, responsible for forming a disaccharide from two monosaccharides.
- Reducing sugars, such as glucose and galactose, have an aldehyde or ketone group and can act as a reducing agent.
- Non-reducing sugars, such as sucrose, do not have an aldehyde or ketone group and cannot act as a reducing agent.
- Lactase is the enzyme essential for breaking down lactose into glucose and galactose.
Glucose and Energy Generation
- Glucose is the preferred nutrient for energy generation.
