Study Notes

Cellular Organelles and Their Functions

  • Mitochondria are responsible for producing ATP (adenosine triphosphate) through aerobic respiration, generating energy for the cell.

Cellular Organelles and Their Functions

  • Nucleus contains DNA organized into chromosomes, storing genetic information.

Cellular Organelles and Their Functions

  • Rough Endoplasmic Reticulum (RER) is responsible for protein synthesis, where ribosomes attached to its surface translate messenger RNA (mRNA) into polypeptide chains.

Cellular Organelles and Their Functions

  • Lysosomes are involved in cellular digestion and recycling, containing digestive enzymes that break down and recycle cellular waste, foreign substances, and damaged cell components.
