Endoplasmic reticulum
D
Golgi apparatus
Verified step by step guidance
1
Understand 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: The structures mentioned in the problem are lysosome, mitochondria, endoplasmic reticulum, and Golgi apparatus.
Determine the role of each structure: The lysosome is involved in digestion and waste processing, the endoplasmic reticulum is involved in protein and lipid synthesis, and the Golgi apparatus modifies, sorts, and packages proteins and lipids for secretion or use within the cell.
Recognize the independence of mitochondria: Mitochondria are not part of the endomembrane system. They are involved in energy production through cellular respiration and have their own DNA, which is separate from the nuclear DNA.
Conclude which structure is independent: Based on the roles and characteristics, mitochondria are independent of the endomembrane system, unlike the other structures listed.
