- AGlucose
- BLipid
- CNeither
- DBoth

17The adipokine Adiponectin is one of the most highly secreted proteins in our blood. Its secretion is generally [blank_start]__________[blank_end] in obesity.
- AReduced
- BIncreased
- CUnaffected
18[blank_start]__________[blank_end] acts to stimulate AMP-kinase to increase β-oxidation [and] increase glucose uptake into the cell.
- AAdiponectin
- BLeptin
- CBoth of the above
- DNeither of the above
19True or false: In addition to being stimulated by some adipokines, AMP-kinase is also regulated by exercise, to stimulate energy expenditure within a cell.
- AVerdadeiro

Hypertrophy = increase in [blank_start]__________[blank_end];
Hyperplasia = increase in [blank_start]__________[blank_end].- ASize
- BNumber
21True or false: Ectopic Lipid Accumulation is the “spill over” when adipocytes reach saturation and lipids start getting into other tissues (e.g. muscle, liver) where it causes metabolic dysfunction.
- AVerdadeiro
- BFalso
22True or false: Lipodystrophy is the “spill over” when adipocytes reach saturation and lipids start getting into other tissues (e.g. muscle, liver) where it causes metabolic dysfunction.
