Golgi apparatus: structure and function

The video tutorial explains the Golgi apparatus, comparing it to a packaging station. It details the structure, including cisterni and networks, and describes its function in processing proteins and lipids. The Golgi apparatus modifies and packages these molecules for transport to various destinations, working closely with the endoplasmic reticulum.

What is the primary function of the Golgi apparatus in a cell?

• To break down waste

• To generate energy

• To package and sort proteins

• To synthesize DNA

Which component of the Golgi apparatus is closest to the endoplasmic reticulum?

• Trans face

• Lumen

• Medial section

• CIS face

What is the role of the lumen in the Golgi apparatus?

• To store genetic material

• To produce ATP

• To modify proteins for transport

• To synthesize lipids

How do vesicles from the endoplasmic reticulum enter the Golgi apparatus?

• Via the CIS face

• Through the trans face

• Directly into the lumen

• Through the medial section

What is the main function of the endoplasmic reticulum in relation to the Golgi apparatus?

• To break down proteins

• To synthesize and transport molecules

• To store calcium ions

• To produce ribosomes

What is the cisternal maturation model?

• A theory about DNA replication

• A model explaining protein synthesis

• A model describing how cisternae move and mature

• A theory about cell division

Where are proteins, lipids, and polysaccharides sent after being processed by the Golgi apparatus?

• To the mitochondria

• To the chloroplasts

• To the nucleus

• To their final destinations in vesicles
