Study Notes
Cell Structure and Function
- Cells contain a nucleolus and chromatin, crucial for genetic function.
- The nucleus undergoes mitosis, a process vital for cell division and replication.
- Chromatin is composed of DNA, organizing genetic material for cell function.
Ribosome Production and Function
- The nucleolus is responsible for synthesizing ribosomes, essential for protein production.
- Ribosomes are used to manufacture proteins, including critical hormones like insulin.
- Ribosomes are located on the endoplasmic reticulum, enhancing their efficiency in protein synthesis.
Endoplasmic Reticulum and Protein Transport
- The endoplasmic reticulum acts as a delivery system for proteins, transporting them within the cell.
Cytoplasm and Organelles
- The cytoplasm contains various organelles including the endoplasmic reticulum, mitochondria, lysosomes, and Golgi body.
- Mitochondria generate ATP, the energy currency of the cell.
- Lysosomes house enzymes that break down various substances, aiding in cellular maintenance.
Golgi Body and Vesicles
- The Golgi body modifies and packages proteins into vesicles for export.
- Vesicles facilitate the export of proteins across the cell membrane.
Cell Membrane Characteristics
- The cell membrane is semipermeable, regulating the passage of substances.
- Being semipermeable enables osmosis and diffusion, maintaining cellular homeostasis.
