Cytology I

This organelle facilitates the assembly of amino acids into polypeptides, which then fold into functional proteins essential for various cellular functions.

• Lysosomes

• Nucleolus

• Ribosomes

• Microtubules

Which of the following statements is False about the Endoplasmic Reticulum?

• The endoplasmic reticulum synthesizes proteins to help build structures, produce enzymes for reactions, and transport substances.

• The endoplasmic reticulum synthesizes lipids, phospholipids, and cholesterol to build cell membranes, hormone production, and protecting the cells.

• The endoplasmic reticulum serves as a network for transporting synthesized proteins and lipids to the Golgi apparatus.

• The endoplasmic reticulum degrades damaged organelles, pathogens, unused macromolecules, and excess nutrients to maintain cellular health.
