Cellular activities encompass all the processes that occur within cells to maintain their homeostasis, growth, and function. These activities include:
Cell Division: The process by which a parent cell divides into two or more daughter cells. This is essential for growth, repair, and reproduction. Protein Synthesis: The creation of proteins based on the genetic instructions carried by mRNA. This involves transcription and translation processes. Energy Production: Cells produce energy through metabolic pathways such as glycolysis and the Krebs cycle, primarily in the mitochondria. Cell Signaling: Cells communicate with each other through signaling molecules, which bind to receptors and trigger specific responses. Transport Mechanisms: Cells transport substances across their membranes via passive and active transport mechanisms, including diffusion, osmosis, and endocytosis.
