BIOL 251 HUMAN ANATOMY & PHYSIOLOGY I W/LAB EXAM
QUESTIONS WITH CORRECT ANSWERS | RATED A+
1. Mitochandria-ANSWER- The part of the cell that converts food to energy.Rod shaped.double
membrane organelles.
folded into cristae. site of aerobic respriation and energy production(ATP)
2. Ribosomes-ANSWER- Makes proteins.non-organelles. composed of rRNA and protein.They
circulate in the cytoplasm or
are attached to the ER
3. Rough ER-ANSWER- membranous tube system continuous with the nucleus and dotted with
ribosomes.protein modifi
cation (suger attachment) and protein transport (placement into vescicles)to the Golgi
apparatus and other sites.
4. Smooth ER-ANSWER- Menbranous tube system free of ribosomes. Lipid and steroid
synthesis.occurs here.as well as lipid
metabolism.
5. Golgi complex-ANSWER- stack of flattened membrances;polar with arriving and leaving sides.
part of the endomem
brane system that package and modifies proteins for secretion from the cell or placement into.
6. Peroxisomes-ANSWER- vesicles filled with oxidase and catalase enzymes. then break down
and detoxify substances that
can damage organelles and DNA. such as free radicals and hydrogen peroxide.
7. Lysosomes-ANSWER- vesicles filled with digestive enzymes. break down macromolecules so
monomers can be recycled.
