ASU BIO 181 QUIZ 2 (MODULE 3 & 4) EXAM ACTUAL 2026/2027
QUESTIONS AND VERIFIED CORRECT ANSWERS
.
Molecular motors use ATP as the energy source to power the
molecular motors.
TRUE
What does the nucleosomal core have in it (i.e., the basket ball
like structure on the slides)?
(2 H2A, 2 H2B, 2 H3, 2H4)
To get into the nucleus a component has to have the correct
signal sequence and pass through a nuclear pore.
TRUE
Which cytoskeletal filament system lines the inside of the
nucleus to protect it?
Intermediate filament system.
, Lamins are type V intermediate filament proteins
Explain the evolutionary origin of mitochondria.
Anaerobic eukaryote engulfed an aerobic alpha-
proteobacterium which then became an endosymbiont
providing ATP from respiration while receiving substrates and
protection
It is a simple matter (i.e., thermodynamically favorable) for a
vesicle to form from the endoplasmic reticulum.
FALSE
Amino acids can be largely subdivided into two groups. What
are the two groups?
Hydrophilic and Hydrophobic.
The ER is contiguous with the Golgi apparatus.
FALSE
What is the difference between a triglyceride and a
phospholipid?
