Study Notes
Cell Organelles
- Plasma Membrane delineates the boundary between extracellular fluid and intracellular fluid, crucial for maintaining homeostasis.
- Intracellular fluid (ICF) consists of water and various dissolved substances such as ions, amino acids, and sugars.
- Organelles are specialized structures within cells that perform distinct functions and house enzymes essential for these activities.
Protein Synthesis: DNA -> RNA -> Protein
Nucleus
- Acts as a control center for protein synthesis.
- Houses DNA, the genetic material that guides cell function.
- Transcription is the process by which messenger RNA (mRNA) is synthesized from DNA.
Ribosomes
- Composed of granules that contain proteins and transfer RNA (tRNA).
- Function as the primary site of protein synthesis within the cell.
- Translation is the process that involves utilizing mRNA to produce proteins, facilitating the expression of genetic information.
- Free ribosomes synthesize proteins that typically function within the cytosol (the liquid component of the cell).
