Answer 1

Answer

17) Cholecystokinin (CCK) is a satiety hormone that indirectly tells your brain that you're full.

• It is released from enteroendocrine cells of small intestine and stimulate bile release.
• It also inhibits hunger.

Option B

18) Digested food travels slowly through the intestines because it allows nutrients to come into contact with the intestinal wall so that they can be transported to circulation. --- TRUE

• Small intestine is the site absorption of all the macronutrients from food.
• Hence, the digested food moves slowly to allows nutrient absorption.

19) According to, The Laws of Thermodynamics energy is never really created nor destroyed - it just moves around or gets transformed from one form to another.

Option B

20) Amino Acids supply the energy for most of our regular functioning --- FALSE

• Carbohydrates (glucose) is the most important source of energy.
• Stored nutrients such as in liver or muscle cells also provides energy for our regular functioning.

21) Triglycerides and glycogen make up the two most important "raw materials" for making ATP in the body.

Option C
