HUN 1201 EXAM 3 QUESTIONS AND
ANSWERS (VERIFIED AND UPDATED)
25-29.9 - ANS a body mass of how many kg/m is considered overweight
30+ - ANS a body mass of how many kg/m is considered obese
body mass index - ANS the ratio of weight to height squared.
40-70% - ANS what percentage does genetics contribute to obesity
leptin - ANS an obesity gene, it is a hormone produced by adipose tissue. the greater the
adipose tissue the more leptin levels increase.
obesity - ANS it is caused by an over abundance of food and lack of activity and can cause
chronic inflammation
chronic inflammation - ANS a condition characterized by a chronically active immune
response which causes invasion of monocytes which spits signals out that leads to cell death
causing metabolic syndrome disorders
food intake - ANS it is controlled by the coordination of the nervous system and hormones
which all control hunger, appetite, and satiety.

, hunger - ANS the need to eat food which is triggered by internal physiological signals. It is
stimulated by low blood glucose and nutrients level and mediated by ghrelin. all takes place in
the hypothalamus and can occur before satiety subsides.
ghrelin - ANS a hormone produced and secreted by the stomach and duodenum which
affects food intake.
appetite - ANS the psychological desire to eat; can exist without hunger.
satiety - ANS the feeling of fullness which occurs both short term and long term and together
they suppress appetite.
short term satiety - ANS (the brakes) it is controlled by the vagus nerve, blood nutrients, and
insulin to produce the feeling of fullness
long term satiety - ANS (turns off engine) it is controlled by leptin to produce the feeling of
fullness
energy expenditure - ANS it has 4 components and can be determined by direct or indirect
calorimetry processes
indirect calorimetry - ANS calculation based on gas exchange (o2/co2). the volume of oxygen
consumed during activity.
direct calorimetry - ANS directly measures the heat produced by an active individual (involves
a chamber)
respiratory exchange ratio - ANS RER- is also useful because it can determine fuel utilization
BMR, physical activity, thermic effect of feeding, growth and adaptation - ANS the 4
components of energy expenditure?
