Where on an enzyme does the substrate bind?

• active site

• allosteric site

• C-terminus

• N-terminus

Which of the following best describes the function of the nucleolus within the nucleus?

• It stores DNA.

• It synthesizes ribosomal RNA.

• It regulates cell division.

• It modifies proteins.

Which organelle is responsible for modifying, sorting, and packaging proteins for secretion?

• Ribosome

• Golgi apparatus

• Endoplasmic reticulum

• Lysosome

A cell is observed to have a large number of lysosomes. What might this indicate about the cell's function?

• It is involved in energy production.

• It is involved in protein synthesis.

• It is involved in waste processing and recycling.

• It is involved in lipid storage.

Explain how the structure of the cell membrane contributes to its function.

• The rigid structure provides support and protection.

• The fluid mosaic model allows selective permeability.

• The thick layer prevents all substances from entering.

• The solid structure allows for easy transport of materials.

Compare and contrast the functions of the smooth and rough endoplasmic reticulum.

• Both synthesize proteins; the rough ER also detoxifies chemicals.

• The smooth ER synthesizes lipids; the rough ER synthesizes proteins.

• Both store calcium ions; the smooth ER also synthesizes proteins.

• The rough ER detoxifies chemicals; the smooth ER stores genetic material.
