2 Organelles and Cellular Organization Online Quiz Questions

Which structure inside the nucleus makes components of ribosomes?

Mitochondria are excluded from the endomembrane system because their membranes do not participate in its trafficking network.

Which organelle lacks ribosomes and contributes to lipid synthesis and calcium storage?

Which organelle further modifies and sorts proteins and lipids received from the ER?

Which structures are included in the endomembrane system? Select all correct choices.

Material taken into a cell can be carried by a vesicle from the plasma membrane to an endosome for sorting.

For a protein destined for secretion, what membrane does the final transport vesicle fuse with to release the protein outside the cell?

A newly made protein will be secreted from the cell. Which ribosome location is most directly associated with making many proteins destined for secretion?

Which statements about lysosomes are correct? Select all correct choices.

Describe the route a protein follows from synthesis at a rough-ER-attached ribosome until it is released outside the cell. Include the role of the ER, transport vesicles, Golgi apparatus, and plasma membrane.

Which plant-cell structure commonly stores water and dissolved substances and helps maintain internal pressure?

During fatty-acid oxidation, a cell must also manage hydrogen peroxide produced by the reactions. Which organelle contains enzymes that help detoxify this hydrogen peroxide?

True or false: Mitochondria are excluded from the endomembrane system because their membranes do not participate in its trafficking network.

Which region of the endoplasmic reticulum lacks ribosomes and contributes to lipid synthesis?

Which organelle receives much of the material arriving from the ER at its cis side?

Which organelle in plants and algae captures light energy to make sugars through photosynthesis?

A cell compartment carries out oxidation reactions and contains enzymes that help detoxify hydrogen peroxide. Which organelle is it?

A cell is making components that will be used to assemble ribosomes. Which nuclear region performs this function?
