AP BIOLOGY: UNIT 2.1 AP EXAM
REVIEW Q&A
How does the structure of a ribosome aid in its function? - Answer-Because ribosomes
are made of ribosomal RNA it aids in its ability to read mRNA. because of its structure it
can take in the mRNA and read it to synthesize proteins
What are the three types of RNA involved in the structure and function of the ribosome?
- Answer-mRNA, rRNA, and tRNA
How does a ribosome demonstrate common ancestry of all known life? - Answer-
Ribosomes demonstrate a common ancestry of all known life because ribosomes are
found in every organism, both prokaryotic and eukaryotic. Ribosomes are vital for
existence of organisms because ribosomes produce the necessary proteins every
organism needs
What is the structure and function of the rough ER? - Answer-The rough ER is a
network of membrane tubes with ribosomes attached to the outside. The Rough ER
packages newly synthesized proteins for export within or out of the cell.
How does the structure of the rough ER aid in its function? - Answer-The ribosomes
attached to the outside of the rough ER create the proteins that are then packaged by
the rough ER.
What is the structure and function of the smooth ER? - Answer-The smooth ER is a
network of membrane tubes that does not have ribosomes attached to it. The smooth
ER synthesizes lipids and detoxifies.
How does the structure of the Golgi aid in the function? - Answer-Golgi membranes
form a unique stacked structure. This allows for key functions such as trafficking,
processing, and sorting of newly synthesized membrane and secretory proteins and
lipids.
What is the structure and function of the mitochondria? - Answer-The mitochondria is
membrane bound, it has two membranes, the inner and outer. The outer membrane is
very smooth, the inner membrane is rough and highly convoluted. The mitochondria
produces ATP.
How does the structure of the mitochondria aid in the function? - Answer-The inner
membrane of mitochondria is rather complex in structure. It has many folds that form a
layered structure called cristae, and this helps in increasing the surface area inside the
organelle. The cristae and the proteins of the inner membrane aid in the production of
ATP molecules.
