Test-Retest Reliability - CORRECT ANSWER The ability to get similar results when
something is measured under the same conditions.
Reliability - CORRECT ANSWER The consistency of a measure.
Validity - CORRECT ANSWER The assessment of whether a tool is measuring what it is
supposed to measure.
Selection Bias - CORRECT ANSWER A sample of people under study is not representative of
the larger population that scientists are looking to make inferences about.
Retrospective - CORRECT ANSWER Describes a study that looks backward in time.
Recall Bias - CORRECT ANSWER The inability to accurately remember past behaviors.
Health - CORRECT ANSWER A state of complete physical, mental, and social well-being, not
merely the absence of disease or infirmity.
Homeostasis - CORRECT ANSWER The tendency toward a relatively stable equilibrium
between interdependent elements, especially as maintained by physiological processes.
Disease - CORRECT ANSWER A disorder of structure or function in a human, animal, or
plant, especially one that produces specific signs or symptoms, affects a specific location, and is
not simply a direct result of physical injury.
Noncommunicable Disease - CORRECT ANSWER A noncommunicable disease (NCD) is a
medical condition or disease that is not caused by infectious agents; it can refer to chronic
diseases which last for long periods of time and progress slowly.
Communicable Disease - CORRECT ANSWER Infectious diseases caused by microorganisms
such as bacteria, viruses, parasites, and fungi that can be spread (directly or indirectly) from one
person to another.
Wellness - CORRECT ANSWER The fluid process of improving the emotional, occupational,
physical, social, intellectual, and spiritual components of life, dynamically leading to a better
state of health and well-being.
,Obese - CORRECT ANSWER A high degree of excess body fat - a BMI greater than 30.
Biometrics - CORRECT ANSWER The technical term for measurements and calculations
related to human physical characteristics.
Satiety - CORRECT ANSWER A feeling of fullness and satisfaction.
Palatability - CORRECT ANSWER The degree of pleasure or taste provided by a food - a
highly palatable food is one that is tasty and pleasant to consume.
Adenosine Triphosphate (ATP) - CORRECT ANSWER The energy currency of life.
chemical compound that provides energy to drive muscle contraction, transmission of nerve
impulses, and the vast majority of chemical reactions that facilitate human life.
Metabolism - CORRECT ANSWER Chemical processes occurring within the body to convert
food to energy.
Thermic Effect of Food (TEF) - CORRECT ANSWER represents the increase in energy
expenditure after consuming a meal.
Thermic Effect of Activity (TEA) - CORRECT ANSWER accounts for the most variability of
daily energy expenditure.
Non-Exercise Activity Thermogenesis (NEAT) - CORRECT ANSWER energy expended for
everything we do that is not sleeping, eating or exercising.
Lipogenesis - CORRECT ANSWER The biological process of combining free fatty acids with
glycerol to form triglycerides.
Lipolysis - CORRECT ANSWER The biological process of breaking stored triglycerides into
free fatty acids and glycerol.
Glycogenolysis - CORRECT ANSWER The process of breaking down the glycogen molecule
into its individual glucose units for entry into the energy pathways.
Gluconeogenesis - CORRECT ANSWER A metabolic pathway that results in the generation of
glucose from non-carbohydrate carbon substrates such as lactate, glycerol and glucogenic amino
acids.
Leptin - CORRECT ANSWER A hormone produced by adipose (fat) cells that acts as a satiety
factor in regulating appetite.
Ghrelin - CORRECT ANSWER A hunger-arousing hormone secreted by an empty stomach.
,CCK (cholecystokinin) - CORRECT ANSWER hormone released in the gastrointestinal system
and is responsible for stimulating the digestion of fat and protein.
NPY (neuropeptide Y) - CORRECT ANSWER neurotransmitter found in several brain areas,
most notably the hypothalamus, that stimulates eating behavior and reduces metabolism,
promoting positive energy balance and weight gain.
Insulin - CORRECT ANSWER hormone produced by the pancreas that is released when blood
glucose levels are high, promoting the uptake of glucose for fuel or storage as glycogen. Insulin
helps keeps blood-sugar levels from getting too high, also referred to as hyperglycemia.
Glucagon - CORRECT ANSWER hormone that is released when blood sugars decrease below a
certain threshold. It stimulates the breakdown of stored glucose (glycogen) in the liver, releasing
additional glucose into the bloodstream for fuel.
ATP-PC system - CORRECT ANSWER energy system producing ATP during high intensity,
short duration exercise. Phosphocreatine decomposes and releases large amount of energy used
to construct ATP. provides energy for muscle contraction for up to 10 seconds.
Anaerobic Glycolytic System - CORRECT ANSWER Glucose is used for fuel and is either
blood glucose or muscle glycogen, broken down in to pyruvic acid, when there is insufficient
oxygen it then is transformed into lactic acid. Energy up to 2 minutes.
Aerobic Energy System - CORRECT ANSWER virtually unlimited capacity for making ATP,
uses carbs, fat, protein for fuel. Slow to produce ATP. Lasts anywhere from 2 minutes to a few
hours.
Acid-Base Balance - CORRECT ANSWER The process of achieving, or the state of,
equilibrium between acidic and alkaline molecules.
Cell Signaling - CORRECT ANSWER Process of communication between cells by biological
messengers to govern cellular function.
Organic Molecules - CORRECT ANSWER Chemical structures containing only carbon,
hydrogen, oxygen, and/or nitrogen.
Amino Acids - CORRECT ANSWER The organic building blocks of proteins containing both a
carboxyl and an amino group.
Essential Amino Acids (EAA) - CORRECT ANSWER Amino acids that are necessary for
bodily functions but cannot be synthesized by the body and, therefore, must be obtained in the
diet.
Phenylalanine
Valine
Threonine
, Tryptophan
Isoleucine
Methionine
Histidine
Arginine*
Lysine
Leucine
Branched Chain Amino Acid - CORRECT ANSWER The three essential amino acids (leucine,
isoleucine, and valine) which are abundant in skeletal muscle tissue and named for their branch-
like structure.
conditionally essential amino acids - CORRECT ANSWER amino acids that are normally
considered nonessential but become essential under certain circumstances when the body's need
for them exceeds the ability to produce them.
nonessential amino acids - CORRECT ANSWER amino acids that the body can synthesize &
normally do not need to be obtained in the diet.
protein synthesis - CORRECT ANSWER Process of joining amino acids with peptide bonds to
form proteins.
dehydration synthesis - CORRECT ANSWER The joining of two large molecules by removing
one hydrogen from one molecule and a hydroxyl group (OH) from another molecule and then
binding the two larger molecules together on the newly freed bonds.
Peptide Bond - CORRECT ANSWER The bond between two amino acids, occurring between
the carboxyl group of one and the amino group of the other.
Hydrolysis - CORRECT ANSWER Breakdown of one large molecule into two smaller
molecules via the donation of one hydrogen and one hydroxyl group from water to the smaller
molecules, respectively.
Dipeptide - CORRECT ANSWER Two amino acids bonded together
tripeptide - CORRECT ANSWER 3 amino acids
oligopeptide - CORRECT ANSWER 4-9 amino acids
Polypeptide - CORRECT ANSWER chain of 10 or more amino acids
Denaturation - CORRECT ANSWER changing the shape of a protein but not its primary
structure.
Denaturation occurs in response to many factors such as temperature, pH, and enzymes, all of
which are at work during protein digestion and absorption.
