Cystic fibrosis is a genetic condition that is associated with defects in the CFTR protein found in the membrane. Which organelle synthesized the protein?

• Golgi Bodies

• Rough ER

• Smooth ER

• Lysosome

How does the location of the ribosome affect the type of protein product?

• free ribosomes synthesize cytosolic proteins while bound ribosomes synthesize membrane proteins

• free ribosomes synthesize membrane proteins while bound ribosomes synthesize cytosolic proteins

• free ribosomes synthesize proteins for the mitochondria while bound ribosomes synthesize cytosolic proteins.

• free ribosomes synthesize cytosolic proteins while bound ribosomes synthesize proteins for the mitochondria.

What is the function of the increase in surface area of rough ER?

• More sites for ATP synthesis

• More sites for digestion

• More sites for lipid synthesis

• More sites for protein synthesis

Active transport requires…

• Energy

• Transport protein

• Both energy & transport protein

• Neither energy nor transport protein

Describe the role of ribosomes in a cell.

• They store genetic information.

• They synthesize proteins.

• They break down waste materials.

• They transport substances across the cell membrane.

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.

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.

What is the primary function of the mitochondria in eukaryotic cells?

• Photosynthesis

• Protein synthesis

• Energy production

• Lipid storage
