BIOL 251: HUMAN ANATOMY & PHYSIOLOGY I W/LAB 2026/2027
ACTUAL QUESTIONS WITH VERIFIED ANSWERS.
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)
Ribosomes - (ANSWER)Makes proteins.non-organelles. composed of rRNA and protein.They circulate in
the cytoplasm or are attached to the ER
Rough ER - (ANSWER)membranous tube system continuous with the nucleus and dotted with
ribosomes.protein modification (suger attachment) and protein transport (placement into vescicles)to
the Golgi apparatus and other sites.
Smooth ER - (ANSWER)Menbranous tube system free of ribosomes. Lipid and steroid synthesis.occurs
here.as well as lipid metabolism.
Golgi complex - (ANSWER)stack of flattened membrances;polar with arriving and leaving sides. part of
the endomembrane system that package and modifies proteins for secretion from the cell or placement
into.
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.
Lysosomes - (ANSWER)vesicles filled with digestive enzymes. break down macromolecules so monomers
can be recycled.
