Study Notes
Cellular Structure
- A cell consists of a cell membrane, cytoplasm, and a nucleus.
- Cytoplasm contains protein fibers, membranous organelles, and inclusions.
- The nucleus contains a nucleolus.
Cellular Organelles
- Cytoskeleton provides structural support and shape to the cell.
- Golgi apparatus and Endoplasmic Reticulum (smooth and rough) are involved in protein synthesis and transport.
- Mitochondria are responsible for generating energy for the cell.
- Ribosomes are involved in protein synthesis.
Levels of Organization
- The integration of structure and function extends across all levels of organization, from molecules to the entire body.
- The theme of compartmentation is the separation of cells into functional compartments, such as organelles, cells, tissues, organs, and organ systems.
Molecular Interactions
- Molecular interactions are essential for biological function.
- A molecule's function depends on its structure and shape, and small changes can have significant effects.
Energy and Homeostasis
- Living organisms require energy for growth, reproduction, movement, and homeostasis.
- Homeostasis is the maintenance of a relatively stable internal environment, attributed to Claude Bernard.
- Homeostasis is essential for normal physiological functions, and disruptions can lead to disease.
Information Flow
- Information flow in living systems ranges from genetic information stored in DNA to the flow of information within a single organism.
- Homeostasis is an essential aspect of information flow in the body, maintaining a stable internal environment.
