1
Q
What are pericytes?
ANSWERS:
Cells that project onto:
endothelial cells
mediating luminal diameter
synthesizing basement membrane components
releasing vasoactive agents
2
Q
What is the thickness of a phospholipid bilayer?
ANSWERS:
Approximately 10 nanometers
This structure is essential for cell membrane integrity and function.
3
,Q
Which apolipoproteins are found on chylomicrons?
ANSWERS:
APO B-47
APO C-II
APO C-III
4
Q
What happens to chylomicrons in the periphery?
ANSWERS:
APO C-II will activate lipoprotein lipase on the capillary
endothelium.
This cleaves the chylomicron and releases fatty
acids and monoglycerides which can then enter the cell.
Remnants of chylomicrons are taken up by hepatocytes.
5
Q
Fats with what length of carbon chain will need to be absorbed via
the lymphatics?
ANSWERS:
More than 12 carbons
6
Q
,What are the parts of a sarcomere?
ANSWERS:
Z-discs: ends of a sarcomere
I band: only actin (thin) filaments
A band: overlap of actin and myosin filaments
H zone: myosin filaments only
M line: anchoring point for thick filaments
7
, Q
Describe the function of the ryanodine receptor on the sarcoplasmic
reticulum.
ANSWERS:
Calcium stimulates the release of more calcium from the sarcoplasmic
reticulum
Inhibited by dantrolene.
8
Q
What are the three main types of receptor on the sarcoplasmic
reticulum?
ANSWERS:
Ryanodine Receptor (CICR)
Inositol Triphosphate Receptor (calcium channel)
Phospholamban (inhibits sarcoplasmic reticulum calcium
ATPase)
9
Q
Describe the structure of myosin.
ANSWERS:
Dimers arranged in a staggered helical fashion with globular
heads in six rows.
Central portion of adjacent filaments joins at the M-disc via
creatine kinase, M protein, and myomesin.
