16
Q

molecules and hormones that adipocytes produce

A

free fatty acid, adiponectin (insulin resistance), cytokines (inflammation), and leptin (appetite control/weight gain)

17
Q

factors that regulate body weight

A

genetic and environment

18
Q

mutation in what gene can produce hyperphagia and massive obesity

A

leptin gene and its receptors

hyperphagia is excessive hunger/increased appetite

19
Q

what secretes ghrelin and cholecystokinin(CCK)

A

ghrelin released by stomach and CCK by small intestine

20
Q

tissues affected by obesity

A

liver, muscle, adipose

21
Q

clustering of atherosclerotic and cardiovascular disease

A

metabolic syndrome

22
Q

risk factors of metabolic syndrome

A

visceral adiposity (obesity), insulin resistance, low levels of HDLs, systemic proinflammatory state

23
Q

indicators of metabolic syndrome

A

elevated fasting blood glucose, elevated waist circumference, elevated TAGs, reduced HDL cholesterol, elevated blood pressure

24
Q

strong correlation between weight gain and …

A

insulin resistance

25
insulin resistance results in..
increased synthesis of VLDL, increased TAGs in circulation, increased risk of atherosclerosis
26
why are people with metabolic syndrome not considered diabetes despite their insulin resistance
they produce enough insulin to keep some of the effects of insulin on target tissues working
27
pharmacologic appetite suppressant that increases fullness
sibutramine (no longer on the market)
28
pharmacologic gastric and lipase inhibitor that inhibits the digestion of TAGs
orlistat
29
BMI of a person considered morbidly obese
>35
30
why is ketone body activation considered very efficient
it does not need an ATP to be activated | you go from beta hydroxybutyrate to acetoacetate and form NADH = 3ATP
31
B2/riboflavin deficiency
cheilosis
32
microcytic anemia can develop from deficiencies in what
vit B6, iron, copper
33
macrocytic anemia can develop from deficiencies in what
vit B12 and folic acid
34
protein calorie malnutrition, energy deficiency is predominant
marasmus
35
cancer, aids, chronic pulmonary and renal disease can lead to
cachexia (loss of appetite and muscle atrophy)
