Study Notes
Terrestrial Biomes
- Defined as areas sharing similar climate, topographic, and soil conditions, and hosting the same basic types of biological communities.
- Temperature and precipitation are among the most important determinants in biome distribution.
Types of Ecosystems
- Marine Ecosystems:
- Open Ocean
- Shallow Coasts
- Freshwater Ecosystems:
- Lakes
- Wetlands
Biome Distribution
- Many biomes occur in latitudinal bands due to temperature control.
Sugars
Types of Sugars
- Monosaccharides are single sugar molecules that cannot be broken down into simpler sugars.
- Glucose, fructose, and galactose are examples of monosaccharides.
- Disaccharides are composed of two monosaccharides and can be broken down into simpler sugars.
- Sucrose, lactose, and maltose are examples of disaccharides, formed by combining glucose with fructose, galactose, or glucose, respectively.
- Polysaccharides are composed of many monosaccharides and can be broken down into simpler sugars.
- Starch, cellulose, and glycogen are examples of polysaccharides.
Classification of Sugars
- Reducing sugars have a free aldehyde or ketone group, allowing them to act as reducing agents.
- Glucose, fructose, and lactose are reducing sugars.
- Non-reducing sugars do not have a free aldehyde or ketone group, preventing them from acting as reducing agents.
- Sucrose and maltose are non-reducing sugars.
Functions of Sugars
- Sugars serve as an energy source for the body through cellular respiration.
- Sugars are structural components, found in cell walls, membranes, and other structural components.
- Sugars function as signaling molecules, involved in cell signaling and communication.
Importance of Sugars
- Sugars are essential nutrients, necessary for proper bodily function and maintenance.
- Sugars are the primary source of energy for the brain.
- Sugars are necessary for proper red blood cell function and maintenance.
