Study Notes
Cellular Structure and Function
- The plasma membrane is a semipermeable membrane that surrounds the cell and regulates the movement of substances in and out.
Nuclear Envelope
- The nuclear envelope is the structure that surrounds the nucleus, composed of a double membrane with pores that allow the exchange of molecules.
Protein Synthesis
- The ribosome is the organelle responsible for the synthesis of proteins, where mRNA is translated into a polypeptide chain.
Cellular Energy Production
- The mitochondria is the organelle known as the 'powerhouse' of the cell, responsible for generating most of the cell's energy through cellular respiration.
Endoplasmic Reticulum Function
- The endoplasmic reticulum (ER) is involved in several functions, including protein synthesis, lipid synthesis, and detoxification, and it also provides a pathway for the transport of molecules between the nucleus and the cell surface.
