ANFS240 3/22 Exam Questions With Correct
Answers
what are the 2 types of fat found within the body? - answers✔✔Brown Fat and Yellow/White Fat
Where is Brown fat found? - answers✔✔In neonates and in hibernating animals; may also be found
in adult mammals, particularly more obese but rare
Where is yellow fat found? - answers✔✔Found in adult mammals, usually around the organs and in
the subcutaneous layer of the skin; also found in bone marrow
Which fat has more mitochondria? - answers✔✔Brown
Where is brown fat located - answers✔✔in fat vesicles instead of large vacuoles- membrane bound
What is brown fat used for? - answers✔✔Thermoregulation
Where is yellow fat located? - answers✔✔In large fat vacuoles- no membrane around this
What is yellow fat used for? - answers✔✔energy and ATP
What are some similarities between the two types of fats? - answers✔✔1. they both have the same
cell growth pathway.
2. they both have proteins
3. they both can switch between each type
What is the pathway of mesenchymal stem cells to mature fat cells? - answers✔✔mesenchymal
stem cell> pre-adipocytes> early lipoblast/adipocyte> intermediate lipoblast/adipocyte> mature
lupocyte/adipocyte

Is fat tissue vascularized? - answers✔✔fat tissue is vascularized bringing in nutrients
what are important functions of the fat tissue? - answers✔✔thermoregulation, cushioning, and
energy storage and release
does the amount of fat made depend on genetics? - answers✔✔yes, some people make pre-
adipocytes more easily but some might not...those who as adults can make brown fat, may be
another fat genetics related tissue
what is the type of fat store in fat cells? - answers✔✔triglycerids..these will form globules due to
being hydrophobic
are fat globules surrounded by a membrane in white/yellow fat? in brown? - answers✔✔Globules
do not form in brown fat; they are in the form of vesicles, which have membranes
Globules in white/yellow far are not surrounded by a membrane due to being hydrophobic
What are Lipase? - answers✔✔catalyzes the breakdown of fats into fatty acids and glycerol or other
alcohols; plays a role in lipolysis
What are perilipin - answers✔✔this is essential for the mobilization of fats in adipose tissue
why is the nucleus pushed to the side inside the fat cells? - answers✔✔the nucleus is pushed to the
side of the fat cell as it accumulates more fat; this is due to being able to accommodate the amount
of fat within the cell
do fat cells die? - answers✔✔no, but if they do, this would cause an inflammatory response
can the pathway form mesenchymal stem cell to mature fat cell be reversed? why or why not? -
answers✔✔yes this can be reversed. this is what occurs when we don't eat or exert a lot of energy;
our fat stores are used for heat and ATP when it is needed, thus when fat is taken out of these cells,
the pathway reverses
