Endomembrane System

What is the function of the rough endoplasmic reticulum?

• Detoxification of harmful chemicals

• Production of lipids

• Production of proteins

• Packaging and distribution of cell products

What gives the rough endoplasmic reticulum its rough appearance?

• Ribosomes

• Golgi apparatus

• Nuclear envelope

• Transport vesicles

Abigail, Mia, and Samuel are studying cell biology. They are particularly interested in the smooth endoplasmic reticulum. They learned that it has some main functions. Can you help them identify these functions?

• It helps in detoxification of harmful chemicals

• It is involved in the production of lipids

• It is responsible for the production of proteins

• It assists in the packaging and distribution of cell products

Noah, James, and Daniel are working on a school project about cell functions. They are discussing the role of the Golgi apparatus. James suggests that it's like a post office within the cell. Is James correct?

• It's like a detox center, neutralizing harmful chemicals

• It's like a factory, producing lipids

• It's like a kitchen, producing proteins

• Yes, it's like a post office, packaging and distributing cell products

• Ribosome

• Nucleus

• Golgi apparatus

What happens to the products that are destined for secretion from the cell?

• They are modified by the Golgi apparatus

• They are packaged into a secretory vesicle

• They are fused with the plasma membrane

• They are broken down by lysosomes

The organelle responsible for protein synthesis within the cell is the ribosome.

• True

• False

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

• Production of proteins

• Detoxification of harmful chemicals

• Modification and packaging of proteins and lipids

• Production of lipids

The endomembrane system includes membrane-based organelles which work together to create, modify, and export cell products like proteins and lipids. These include:

• Endoplasmic reticulum, Golgi apparatus, and lysosomes
• Mitochondria, chloroplasts, and peroxisomes
• Nuclear envelope and several vesicle types

• Cytoskeleton, cell wall, and plasma membrane

The organelle responsible for protein synthesis within the cell is ribosome.

• True

• False
