Here's why:
* Organelles are structures within cells: They are like tiny organs that perform specific functions, like energy production (mitochondria), protein synthesis (ribosomes), or waste removal (lysosomes).
* Proteins are molecules: They are made up of chains of amino acids and have various roles in the cell, like acting as enzymes, structural components, or signaling molecules.
Where proteins are made:
* Ribosomes: These organelles are responsible for protein synthesis. They read the genetic code from mRNA (messenger RNA) and assemble amino acids into proteins.
* Endoplasmic reticulum (ER): This network of membranes is involved in protein folding, modification, and transport.
* Golgi apparatus: This organelle further processes and packages proteins before they are sent to their final destinations within the cell or outside the cell.
So, while proteins are not made *of* organelles, they are produced and processed *by* organelles.
