APHY 102 MIDTERM EXAM - IVY TECH
WITH QUESTIONS AND ANSWERS 100%
VERIFIED
Describe carbohydrates - correct answer_ Organic compounds,
including sugars and starches
Describe lipids - correct answer_ organic compound that is not soluble
in water and makes up biological membranes
Describe proteins - correct answer_ enzymes and amino acids
Example of carbohydrates - correct answer_ sugars and starches
Example of proteins - correct answer_ enzymes
Example of lipids - correct answer_ fats and oils
,2|Page
incomplete proteins - correct answer_ proteins that lack one or more of
the essential amino acids
complete proteins - correct answer_ contain all essential amino acids
essential amino acids - correct answer_ Amino acids that are needed,
but cannot be made by the body; they must be eatin in foods
nonessential amino acids - correct answer_ amino acids that can be
manufactured by the body in sufficient quantities and therefore do not
need to be consumed regularly in our diet
What is metabolic acidosis? - correct answer_ An accumulation of acids
as a byproduct of metabolism
,3|Page
How is metabolic acidosis caused? - correct answer_ When the body
produces too much acid or the kidneys are not removing enough acid
from the body
What is produced during nucleic acid metabolism? - correct answer_
protein/polypeptide chain
How is water involved in metabolism? - correct answer_ Water is the
medium for various enzymatic & chemical reactions in the body. It
moves nutrients, hormones, antibodies and oxygen through the blood
stream and lymphatic system.
Which metabolic reactions release hydrogen ions into body fluids? -
correct answer_ Anaerobic respiration of glucose, aerobic respiration of
glucose, incomplete oxidation of fatty acids, Oxidation of sulfur-
containing amino acids
What is cholesterol? - correct answer_ A waxy, fat like substance
, 4|Page
What is the role of cholesterol? - correct answer_ Keeps phospholipid
layer membrane at an optimal fluidity. At high temps it reduces fluidity
and at low temps it increases it.
It does this because it is ampipathic, meaning it is both hydrophobic
and hydrophillic. Therefore it can associate with both parts of the cell
membrane.
What is the difference between fat and water soluble vitamins? -
correct answer_ Fat soluble vitamins dissolve in fats and are influenced
by lipids.
Water soluble vitamins include vitamins B and C
What are the roles of vitamins and minerals in the body? - correct
answer_ Both are essential for normal metabolism. Vitamins are
organic compounds. Minerals are inorganic elements.
Why is vitamin A important? - correct answer_ Normal vision, immunity
and reproduction, also helps heart,lungs,kidney and other organs
working properly
