Question
1.A reticulated network of membranes with attached ribosomes is a good description of which of the following?
Rough endoplasmic reticulum
Smooth endoplasmic reticulum
lysosomes
2.Which of the following is the next organelle that proteins synthesized by the rough endoplasmic reticulum are likely to encounter?
Golgi apparatus
Rough endoplasmic reticulum
lysosomes
3. If a protein is found in the interior of the endoplasmic reticulum, which statement is FALSE?
It will end up in the cytoplasm
It may be secreted to the outside of the cell
It could be targeted to a lysosome or vacuole
4. Which organelle is primarily involved with detoxification?
Golgi apparatus
Rough endoplasmic reticulum
Smooth endoplasmic reticulum
5. A cell involved in the capture and degradation of bacteria (like white blood cells in our body) would probably have an abundance of which of the following organelles?
Golgi apparatus
Smooth endoplasmic reticulum
lysosomes
Rough endoplasmic reticulum
Smooth endoplasmic reticulum
lysosomes
Explanation / Answer
Answers:
1. Rough Endoplasmic reticulum - The RER (Rough endoplasmic reticulum) form the interconnected network and studded with ribosomes on the surface.
2. Golgi apparatus - it pakages proteins into membran-bound vesicles that synthesized by RER.
3. It may be secreted to the outside of the cell
4. Smooth Endoplasmic reticulum is involved in detoxification.
5. Lysosomes are the organelles that work like macromolecules of immune system.
