    Study Notes

    Ribosomes: Protein Synthesis

    • Ribosomes are cellular organelles responsible for protein synthesis.
    • They translate genetic code from messenger RNA (mRNA) into proteins.

    Golgi Apparatus: Protein Packaging and Modification

    • The Golgi apparatus is a membrane-bound organelle.
    • It functions in modifying, sorting, and packaging proteins for secretion.

    Smooth Endoplasmic Reticulum: Detoxification

    • The smooth endoplasmic reticulum (SER) is a network of interconnected membranes within the cytoplasm of eukaryotic cells.
    • One of its key functions is detoxification of harmful substances.

    Prokaryotic vs. Eukaryotic Cells: Membrane-Bound Nucleus

    • Prokaryotic cells lack a membrane-bound nucleus and other membrane-bound organelles.
    • Eukaryotic cells contain a membrane-bound nucleus that houses their genetic material.

    Mitochondria: Energy Production

    • The mitochondria is a double-membrane-bound organelle.
    • Its primary function is to generate energy (ATP) through cellular respiration.
