Cells and endomembrane system

A cross section of part of a Golgi complex is shown. Part of the membrane of the Golgi complex pinches off and moves away. Which of the following is a function of this process?

• to release energy from ATP

• to deliver proteins to other locations in the cell

• to collect amino acids for use in protein synthesis

• to sent messages about cell requirements to the nucleus

Which of the following statements correctly matches a cell part with its function

• The cell membrane packages lipids for export
• The mitochondria perform photosynthesis
• The lysosome digests molecules
• The nucleus produces energy

Keratin is a protein found in hair. Where in a cell is keratin made?

• nucleus

• vacuole

• ribosomes

• mitochondria

After a protein is constructed at the ribosome, it can be transported to the Golgi complex for modification. What cellular structure is used in this transport?

• Lysosome
• Mitochondrion
• Nuclear pore
• Endoplasmic reticulum

Tay-Sachs disease is a human genetic abnormality that results in cells accumulating and becoming clogged with very large and complex lipids. Which cellular organelle must be involved in this condition?

• the endoplasmic reticulum

• the Golgi apparatus

• the lysosome

• membrane-bound ribosomes

Liver cells are specialized cells that carry out a multitude of tasks, including the synthesis of cholesterol and the breakdown of protein metabolites. These cells would be expected to contain a large proportion of which organelle relative to all others?

• smooth ER

• rough ER

• golgi

• nucleolus

Modifies lipids and proteins from the ER; sorts them and packages them in vesicles

• Smooth ER
• Rough ER
• Nucleolus
• Golgi Apparatus

Synthesizes lipids, stores calcium, detoxifies drugs and poisons

• Rough ER
• Smooth ER
• Golgi Apparatus
• Peroxisomes

Synthesizes proteins and packages them in vesicles; vesicles commonly go to the Golgi Apparatus

• Rough ER
• Smooth ER
• Nucleolus
• Nucleus

Fuse with the plasma membrane

• Golgi Apparatus
