Golgi Apparatus

What are the three regions of the Golgi apparatus?

Cis-Golgi, Medial-Golgi, Trans-Golgi.

What is the function of the Cis-Golgi region?

Receives vesicles from the endoplasmic reticulum (ER).

What are the three regions of the Golgi apparatus?

Cis-Golgi, Medial-Golgi, Trans-Golgi.

What is the function of the Cis-Golgi region?

Receives vesicles from the endoplasmic reticulum (ER).

What process occurs in the Medial-Golgi?

Modification of proteins and lipids.

What is the role of the Trans-Golgi?

Packages and sends molecules to their final destinations.

What modification does the Golgi apparatus add to proteins during processing?

Adds carbohydrates (glycosylation) and phosphate groups (phosphorylation).

What is one of the main functions of the Golgi apparatus?

Sorting and packaging proteins to lysosomes, plasma membranes, or secretions.

What are the structural features of mitochondria?

Double membrane, cristae, matrix, and own DNA (mtDNA).

What is the primary function of the mitochondria?

ATP production via cellular respiration.

What are the structures of the rough endoplasmic reticulum (Rough ER)?

Ribosome-studded membrane network.

What is the main function of the smooth endoplasmic reticulum (Smooth ER)?

Lipid synthesis, detoxification, and calcium storage.

How does the Golgi apparatus relate to diseases such as Alzheimer’s and Parkinson’s?

It is involved in protein misfolding related to these diseases.
