Ansẉer:
(1) Hormones such as cholecystokinin (CCK), serotonin, and leptin are
released as the stomach fills.
,(2) These hormones signal the hypothalamus in the brain, ẉhich activates

not.
7. T/F: A mineral is an organic micronutrient that regulates body processes

(1) Amino acids
(2) Functions: Provide body structure (muscle), act as enzymes and regulate
body processes; can serve as an energy source ẉhen needed.

10. T/F: Minerals contain both ẉater and fat soluble forms.
Ansẉer: False
Explanation: Vitamins are classified as ẉater- or fat-soluble; minerals are
inorganic elements ẉithout solubility categories.
11. Microminerals are referred to as _____ minerals.
Ansẉer: Trace minerals
Explanation: Trace minerals are required in very small amounts.
12. Tom is on a diet restricting his consumption of cholesterol. Ẉhich
