Study Notes
Cell Function Overview
Cell function refers to the various activities and processes that take place within a cell to maintain its survival, growth, and response to its environment.
Cellular Processes
- Metabolism: the process of converting energy and nutrients into the components that make up a cell
- Protein Synthesis: the process of creating proteins, which are essential for cellular structure and function
- Cell Division: the process of a cell dividing into two daughter cells, including mitosis and meiosis
- Cell Signaling: the process of cells communicating with each other through signaling pathways
- Transportation: the movement of molecules and ions into and out of the cell
Cell Functions by Organelle
- Nucleus: contains genetic material, regulates gene expression
- Mitochondria: generates energy for the cell through cellular respiration
- Endoplasmic Reticulum (ER): involved in protein synthesis, transport, and modification
- Ribosomes: site of protein synthesis
- Lysosomes: responsible for cellular digestion and recycling
- Golgi Apparatus: involved in protein modification and transport
- Plasma Membrane: regulates the movement of molecules into and out of the cell
Cellular Responses
- Homeostasis: the ability of a cell to maintain a stable internal environment despite changes in the external environment
- Adaptation: the ability of a cell to change its structure or function in response to changes in the environment
- Cellular Defense: the cell's ability to defend itself against pathogens, toxins, and other harmful substances
