Questions and Answers
Nitrogen - ANSW-Unlike carbs and fats, proteins contain:
4 - ANSW-Proteins provide _kcal/gm?
Amino Acids - ANSW-What form are is essential nitrogen stored as?
regulate and maintain - ANSW-Proteins _______ and _________ body functions.
Amino Acids - ANSW-What are the building blocks of protein?
9 - ANSW-How many essential amino acids are there?
Infancy - ANSW-Needs for protein are highest during:
11 - ANSW-How many nonessential (can be synthesized by the body) amino acids are there?
Must be supplied by the diet and is needed for daily bodily functions. - ANSW-Essential
branched chain amino acids. - ANSW-Isoleucine, Leucine, and Valine are:
fueling muscles during activity - ANSW-what are branched chain amino acids used for?
the amino acid that is in the shortest supply in the diet in relation to body needs. - ANSW-What is the
limiting amino acid?
proteins. - ANSW-when amino acids bond, ________ are formed.
peptide bond. - ANSW-the bond between amino acids is a:
protein synthesis - ANSW-DNA contains coded instructions for ________ _________ within the nucleus
of the cell.
cytoplasm of the cell - ANSW-Where does protein synthesis occur?
mRNA - ANSW-a transcribed segment of DNA that is transferred to the cytoplasm is:
transcription. - ANSW-the process from DNA to mRNA is:
shape. - ANSW-the order of the amino acids in a protein determines its:
disease. - ANSW-if the amino acid sequence is mutated, the final shape is disrupted, causing:
one amino acid changes, like glutamic acid to valine. It occurs on two of the subunits, and creates a
change in protein organization, which creates the disease state. This causes the hemoglobin to contain 4
subunits. - ANSW-What causes sickle cell anemia?
decrease in oxygen to cells, severe pain in joints/bones, headaches, abdominal pain, convulsions, and
paralysis. - ANSW-What are the symptoms of sickle cell anemia?
alteration of a protein, three dimensional structure, usually by heat, enzymes, acid or alkaline solutions,
or agitation. - ANSW-Denaturation
alteration of function, often destroys normal physiological functions, but is useful for some body
processes, like digestion. - ANSW-Results of denaturation:
70 % - ANSW-animal sources make up what percentage of protein in the American diet?
magnesium, fiber, and other micronutrients and phytochemical. - ANSW-plant sources of protein
contribute:
provide all essential amino acids, support body growth and maintenance. - ANSW-High Quality
(Complete) Protein:
, low or lack in one or more essential amino acids. - ANSW-Low Quality (Incomplete) Proteins:
2 or more incomplete proteins can be combined to make a complete protein. - ANSW-Complementary
Proteins
plant protein - ANSW-Nuts, seeds, legumes, quinoa, and soy are good sources of:
cooking in heat, and the acid in the stomach (gastrin and pepsin) - ANSW-Ways protein is denatured
during digestion:
stimulates release of acid and pepsin - ANSW-Gastrin
breaks down proteins - ANSW-Pepsin
release of CCK, pancreatic enzyme is released into the small intestine, trypsin is released into the
duodenum, then ready for absorption. - ANSW-Digestion of Protein in the Small Intestine
amino acids are sent to the liver, via the portal vein, which connects the small intestine to the liver. -
ANSW-How are proteins absorbed through active absorption?
muscles, hormones, and enzymes. - ANSW-Proteins are the building blocks of:
fluid maintenance as well as acids and bases. - ANSW-Proteins balance:
immune - ANSW-Promotes promote __________ function:
cells produce proteins that are needed and are disassembling ones that are not. Intestinal tract cells are
sloughed off and digested. - ANSW-Protein Turnover
the process of rebuilding and repairing body proteins slows down. - ANSW-As prolonged protein
inadequacy prolongs:

disease - ANSW-Plant based diets are good for ___________ prevention.
Phytochemical - ANSW-______________ lower cholesterol, prevent blood clots, and relax blood vessels.
plant based diets. - ANSW-Frutarian, Lactovegetarian, Lactoovovegetarian, and vegan diets are all types
of:
includes dairy - ANSW-Lactovegetarian:
includes dairy + eggs - ANSW-Lactoovovegetarian:
Riboflavin - ANSW-leafy greens, whole grains, yeast, and legumes are all good sources of:
fortified foods and sun exposure. - ANSW-Good sources of Vitamin D are (in a plant based diet):
fortified cereals and supplements. - ANSW-Good sources of Vitamin B-12 are (in a plant based diet):
whole grains, dried fruits, nuts, legumes. - ANSW-Good sources of Iron are (in a plant based diet):
complementary proteins and energy dense foods. - ANSW-A major key in plant based diets is:
infants, children, picky eaters, lack of iron, B-12, vitamin D, and calcium. High fiber may limit calorie
intake. - ANSW-Special concerns for vegetarians are:
is the state in which energy intake, in the form of foods and drinks, matches energy expenditure,
primarily through basal metabolism and physical activity. - ANSW-Energy Balance:
