BIOD 121 FINAL EXAM EXPECTED
QUESTIONS AND CORRECT ANSWERS
Name the key hormone that causes a feeling of
hunger. Indicate where in the body it is produced and
the process by which it operates.
Ghrelin is produced by the stomach and travels to the
brain to stimulate the hunger center as it deactivates the
satiety center.
Name the four types of external forces that influence
our eating habits and patterns and give an example of
how you experience each in your life.
1. Sensory ex. smell
2. Cognitive ex. advertising
3. Environmental ex. economics
4. Health Status ex. age
An individual's health can be assessed using the
ABCDE's of nutritional assessment. Below, indicate
what each letter represents.
A - Athropometrics- measurements of body composition
such as height and weight
B - Biochemical- measurement of nutrients in blood, urine
and feces
C - Clinical - physical exam and general appearance, of
the skin, eyes, tongue, teeth, throat, blood pressure, and
mobility.
D - Dietary- review of dietary intake and assessment
E is Environmental. It reviews a person's living conditions
as well as their background history, which included
,medical history, medication review, social history and so
on.
Describe in detail the role that the hypothalamus plays
in determining whether or not you feel like eating.
When we have not eaten for a period of time, the amount
of nutrients in the blood begin to decline. This drop
stimulates the feeding center in the hypothalamus which
signals us to eat.
When the nutrient level of the blood begin to rise, the
satiety center is activated and our desire to continue to eat
declines.
Name the key hormone that causes a feeling of
satiety. Indicate where in the body it is produced and
the process by which it operates.
Leptin is produced by the fat cells which are also known
as adipose tissue. The role of leptin is to alert the brain to
turn off the hunger center and activate the satiety center
when consuming a meal.
There are six classes of nutrients. Name four that
provide structure.
Protein, fat, mineral and water
There are six classes of nutrients. Name four that
regulate body processes.
Proteins, fat, vitamins, minerals and water
MyPlate illustrates 3 concepts. Name the concepts.
Balance, variety and moderation
According to the Dietary Guidelines 2020-2025, three
key dietary principles of the Dietary Guidelines are
1. Meet nutritional needs primarily from nutrient dense
foods and beverages
,2. Choose a variety of options from each food group
3. Pay attention to portion size
There are six classes of nutrients. Name three that are
considered macronutrients.
Carbohydrates, Protein, Fats, Water
Explain the differences between hunger and appetite.
Hunger is the internal drive to find and eat food. It is often
experienced as a negative sensation.
Appetite is the external drive that encourages us to find
and eat food. It is related to pleasant sensations
associated with food.
Multiple Choice:
_____ and _____ are often the 2 most important
reasons specific foods are consumed in North
America.
Taste; texture
Nutrition is the science that links foods to _____ and
______.
health; disease
You are at an "all you can eat'' buffet. On the first pass
through the line, you fill your plate with a large
quantity of foods. After eating it, you go back for a
second portion of the foods you liked. However, the
food is less appealing the second time around, and
you place a smaller quantity on your plate because
you feel full. Considering the physiology as you eat,
(1) explain what hormones are released (list
specifically) as the stomach stretches. (2) List the area
of the brain that provides neural regulation and
appetite suppression to inhibit eating.
, 1. As the stomach is filled and stretches, hormones are
released that cause satiety (Leptin, serotonin,
cholecystokinin (CCK).
2. These hormones can travel to the brain (hypothalamus)
and activate the satiety center.
True or false. If false, explain why it is false.
Minerals promote growth and development, maintain
tissues and cells, fuel the body for physical and
metabolic work, and regulate body processes.
FALSE: Nutrients promote growth and development,
maintain tissues and cells, fuel the body for physical
and metabolic work, and regulate body processes.
OR
A mineral is an inorganic micronutrient that regulates
body processes and provides structure.
A ______ is needed in large amounts in the body,
whereas ______ are needed in small amounts.
Macronutrient; micronutrients
Which is an inorganic macronutrient?
Water
List (A) the building blocks (or monomers) of
PROTEINS, (B) at least 2 of their functions, and (C) at
least 2 common sources of the nutrient in the diet.
List (A) the building blocks (or monomers) of
PROTEINS, (B) at least 2 of their functions, and (C) at
