Here's why:
* Vesicles are cellular structures: Vesicles are small, membrane-bound sacs within cells that act as transport vehicles.
* Proteins are the workhorses of the cell: Proteins are the primary building blocks and functional components of cells. They perform a wide range of tasks, including:
* Acting as enzymes, catalysts for cellular reactions
* Providing structural support
* Transporting molecules
* Communicating signals within and between cells
* Proteins are targeted for transport: When a protein needs to be moved from one part of the cell to another, it's often packaged into a vesicle. The vesicle's membrane forms a protective "envelope" around the protein, ensuring its safe delivery.
Key takeaway: Proteins are made of amino acids, and the process of protein synthesis (translation) is how the cell creates these vital molecules.
