Adipose tissue

Question 1

what is adipose tissue?

Answer 1

its modified connective tissue with a unique cellular make up

Question 2

what are the two adipocytes?

Answer 2

white and brown

Question 3

T/F White fat exists at birth and have larger mitochondria

Answer 3

false its brown

Question 4

what are white adipocytes?

Answer 4

they are the primary adipocytes

Question 5

where does adipose tissue occur at?

Answer 5

visceral
subcutaneous
intermuscular
intramuscular

Question 6

when does the development adipose tissue occur?

Answer 6

post and prenatal

Question 7

visceral is the ______ depot to mature

Answer 7

earliest

Question 8

subcutaneous is the _____ layer to develop

Answer 8

2nd, its the external fat

Question 9

intermuscular fat is the ______ layer to develop

Answer 9

3rd, its located between muscles

Question 10

immature adipocytes contain what?

Answer 10

cytoplasma

Question 11

when the adipocyte is mature 95% of it is what?

Answer 11

TAGs

Question 12

what is the excess energy stored as?

Answer 12

triacylglycerols (TAGS)

Question 13

what is lipoprotein lipase?

Answer 13

extracellular enzymes bound to the endothelial cells of capillaries of adipose tissue

Question 14

what is lipoprotein activated by?

Answer 14

insulin

Question 15

fatty acids are transported across the plasma membrane achieved through two means

Answer 15

passive diffusion and protein-mediated transporters

Question 16

what does passive diffusion do for uptake?

Answer 16

it dissolves across the plasma membrane but is inefficient when FFAs concentrations are limited

Question 17

what does protein-mediated transporters do for uptake?

Answer 17

its efficient at low FFA concentrations, its selective for specific chain lengths or saturation and is regulated by hormones, nutrition, and physiological demands

Question 18

what are triacyglycerols?

Answer 18

the primary form of lipids within the adipocytes

Question 19

what are other forms of lipids?

Answer 19

phospholipids and sterols

Question 20

T/F Adipose tissue is very metabolically active?

Answer 20

True

Question 21

what is lipid accumulation a function of?

Answer 21

absorption of performed FA from the blood
FA synthesis and TAGs formation
lipolysis (breakdown of TAGs)

Question 22

what is lipogenesis?

Answer 22

conversion of fatty acids and glycerol into lipids which is achieved through esterification

Question 23

what are the two methods of accumulating lipids?

Answer 23

extraction of FA from circulating TAGs and De Nova synthesis
