Which structure is part of the endomembrane system?
a. Mitochondrion
b. Golgi apparatus
c. Chloroplast
d. Centrosome

Verified step by step guidance
1
Understand the concept of the endomembrane system: The endomembrane system is a group of membranes and organelles in eukaryotic cells that work together to modify, package, and transport lipids and proteins. It includes the nuclear envelope, endoplasmic reticulum, Golgi apparatus, lysosomes, and vesicles.
Identify the structures listed in the options: (A) mitochondrion, (B) Golgi apparatus, (C) chloroplast, (D) centrosome.
Recall the function and location of each structure: Mitochondria are involved in energy production and are not part of the endomembrane system. Chloroplasts are involved in photosynthesis and are also not part of the endomembrane system. Centrosomes are involved in cell division and are not part of the endomembrane system.
Focus on the Golgi apparatus: The Golgi apparatus is a key component of the endomembrane system. It is involved in modifying, sorting, and packaging proteins and lipids for secretion or delivery to other organelles.
Conclude that the Golgi apparatus is the correct answer: Based on the definition and components of the endomembrane system, the Golgi apparatus is the structure that is part of the endomembrane system.

Key Concepts

Here are the essential concepts you must grasp in order to answer the question correctly.

Endomembrane System

The endomembrane system is a group of interacting organelles within eukaryotic cells that work together to modify, package, and transport lipids and proteins. It includes the nuclear envelope, endoplasmic reticulum, Golgi apparatus, lysosomes, and vesicles, but excludes organelles like mitochondria and chloroplasts.

Golgi Apparatus

The Golgi apparatus is a key component of the endomembrane system, responsible for modifying, sorting, and packaging proteins and lipids for secretion or delivery to other organelles. It consists of stacked membrane-bound sacs and plays a crucial role in processing cellular products.

Golgi Apparatus

Mitochondrion and Chloroplast

Mitochondria and chloroplasts are not part of the endomembrane system. They are involved in energy conversion processes—mitochondria in cellular respiration and chloroplasts in photosynthesis. These organelles have their own DNA and double membranes, distinguishing them from the endomembrane system components.
