Topic 2.1 AP Bio

Which is NOT descriptive of the nucleus?

• Contains DNA and genes

• Make ribosomes

• Control center of the cell

• Contains the "blueprints" for running the cell

What is the main difference between the rough and smooth ER?

• The rough is attached to the nucleus; the smooth is not.

• The smooth has not finished its formation.

• The rough has ribosomes attached; the smooth does not.

• The rough has more genes than the smooth.

What are two functions of the smooth ER?

• Make proteins

• Break down toxins

• Make ATP

• Produce enzymes

• Produce lipids

Lysosomes _______ down materials when they aren't used/needed.

What is true of the cell's vacuoles?

• They are found only in plants.

• They act as "storage containers".

• They are found only in bacteria.

• They produce, modify, and store proteins.

What are the mitochondria and chloroplasts most closely associated with?

• energy

• storage of organic molecules

• DNA

• produce lipids

Ribosomes consist of two components; what are they?

• None of these, DUH!

• DNA and proteins

• Proteins and RNA

• DNA and RNA

Explain why mRNA moves through the middle of the ribosome?

The Golgi apparatus (or complex) is in charge of

• taking organic molecules produced in the nucleus and shipping them to the ER.

• taking organic molecules produced in the ER and shipping them to where they need to go.

• taking organic molecules produced in the ER and shipping them to the nucleus to be used in transcription.

Provide 2 of the functions of the lysosome.
