low concentration to an area of high concentration? - ✔✔Active transport
✔✔True or False:
Gastrin is a vital glycoprotein produced in the stomach and is necessary for the B12 to
be absorbed. - ✔✔False:

✔✔List a dietary treatment for constipation. - ✔✔Eat high-fiber foods
Increase liquid intake
✔✔List a dietary treatment for diarrhea. - ✔✔Increase fluid consumption to prevent
dehydration
Diet: broth, tea, toast, low-fiber
✔✔Below are two clients with digestive ailments. For each of them explain which fiber
should be added to their diet and how it will improve their symptoms.
Client 1 suffers from constipation
Client 2 has high cholesterol - ✔✔Client 1 should consume insoluble fiber because it
won't dissolve and thus increase stool weight, therefore increasing stool speed and
movement.
Client 2 should consume soluble fiber, which will slow glucose and fat absorption, and
therefore lower cholesterol.
✔✔(A) Explain how type 1 diabetes occurs and the disease's symptoms. (B) Detail at
least 3 ways it is different from type 2 diabetes. - ✔✔A: Type 1 diabetes occurs when for
whatever reason, the pancreas loses the ability to produce insulin. Symptoms are
excessive thirst, urination, hunger, weight loss, and ketosis.
B: Reasons it is different from Type 2:
- Type 2 caused by insulin resistance or low insulin production
- Type 2 associated with being overweight
- Type 2 has adult onset
- Type 2 is treated with oral medications whereas Type 1 is treated with insulin

single bond in the fatty acid. - ✔✔False: True or false. If false, explain why it is false.
The '3' and '6' in omega 3 and omega 6 refer to the placement of the first carbon-carbon
double bond. in the fatty acid.
✔✔Describe why LDL is considered a marker of cardiovascular health. Explain where it
is made, it's main components and function in your answer. - ✔✔LDL carries cholesterol
from the liver to the cells. If there are high amounts of LDL, that indicates poor CV
health due to excess cholesterol in the arteries.

Foods that are high in sugar are also good sources of fiber. - ✔✔False. Foods that are
high in STARCH are good sources of fiber.
✔✔The pancreas plays a role in blood sugar regulation. For (A) the fasting, and (B) the
fed states, list the hormones the pancreas releases and their effect on blood glucose. -
✔✔Fasting state: glucagon released to break down glycogen stores in the liver and
increases blood sugar levels
Fed state: pancreas releases insulin. Cellular uptake of glucose increases and lowers
BG level
✔✔State when one's energy intake is equal to amount expended - ✔✔Energy balance
✔✔Components of Energy Expenditure - ✔✔BMR (60-70%)
Thermic Effect of Food (10%)
Thermogenesis
Physical activity (15-40%)
✔✔What method of calorimetry is this?
An insulated chamber surrounded by a thin layer of water is used to measure the
amount of heat emitted by the subject in the chamber. - ✔✔Direct calorimetry
✔✔This method uses oxygen intake and carbon dioxide output, along with scientific
formulas, to measure energy expended. - ✔✔Indirect calorimetry
, ✔✔List the various approaches for determining healthy body standards and the
problems with each. - ✔✔Height-to-weight tables: attempted to link longevity to weight,
but didn't account for individual differences.

✔✔Set point theory - ✔✔Theory that we have a genetically predetermined body weight
and that the body will resist change beyond this set point.
