Eukaryote cells have a nucleus and other organelles.
Eukaryote cells have a cytoskeleton of microscopic protein fibers that provide the structural framework for the cell and its organelles. There are three different kinds of cytoskeleton fibers: actin fibers, microtubules, and intermediate fibers.
In eukaroytic cells, proteins are manufactured at ribosomes found within the cytoplasm and found on an internal membrane system called the rough endoplasmic reticulum (ER).
Packaging and Distribution of Proteins I
n eukaroytic cells, vesicles carry proteins from the rough ER to an internal membrane system, called the Golgi apparatus, to be processed. Modified proteins are either released from vesicles outside the cell or remain in the cell.
