Study Notes

Protein Synthesis and Endomembrane System

Polypeptides are synthesized on ribosomes, which can be found free in the cytoplasm or attached to the rough endoplasmic reticulum.
The rough endoplasmic reticulum is responsible for the synthesis of polypeptides and is characterized by the presence of ribosomes attached to its surface.
The main function of the rough endoplasmic reticulum is to synthesize and modify proteins.

Endomembrane System

The endomembrane system consists of the rough endoplasmic reticulum, smooth endoplasmic reticulum, Golgi apparatus, and lysosomes.
The Golgi apparatus is responsible for modifying, packaging, and transporting proteins and lipids.
Lysosomes contain digestive enzymes and are responsible for cellular digestion and recycling.
The Golgi apparatus provides an acidic environment for its enzymes.

Organelle Functions

The smooth endoplasmic reticulum is involved in lipid synthesis, detoxification, and storage, and is characterized by the absence of ribosomes.
The rough endoplasmic reticulum is abundant in cells that secrete proteins.
The Golgi apparatus is responsible for packaging secretory proteins into transport vesicles.
The nucleolus is involved in the genetic control of the cell and is responsible for ribosome synthesis.
The nuclear envelope is a double membrane structure that separates the nucleus from the cytoplasm and regulates the movement of molecules.

Cellular Components

Free ribosomes are found in the cytoplasm and are responsible for synthesizing proteins that are used within the cell.
The ribosomes are the site of protein synthesis, where genetic information is converted into proteins.
