Protein
This metabolic process removes an amino group from an amino acid and is considered a form of catabolism.
Deamination
This is the main form in which dietary lipids are consumed and stored in the body.
Triglycerides
This process breaks down glucose into two pyruvate molecules and yields a net of 2 ATP.
Glycolysis
These essential nutrients are organic compounds required in small amounts for normal body function.
Vitamins
This process is the breakdown of macronutrients to produce ATP.
Catabolism
This transport mechanism moves nutrients across a membrane without requiring ATP.
Facilitated diffusion
This lipoprotein is responsible for transporting dietary (exogenous) lipids from the intestine to tissues.
Chylomicron
This pathway produces NADPH and ribose-5-phosphate for fatty acid and nucleotide synthesis.
Pentose phosphate pathway
This category of vitamins is stored in body tissues and requires fat and bile for absorption.
Fat-soluble vitamins
This organ is the primary site where most nutrient absorption occurs due to its villi and large surface area.
Small intestine
Which disease is caused by protein deficiency with low to normal energy intake.
Kwashiorkor
This substance, made in the liver from cholesterol, helps emulsify fats during digestion.
Bile
This hormone promotes gluconeogenesis and glycogen breakdown in the liver.
Glucagon
This set of dietary reference values meets the needs of nearly all (about 98%) healthy individuals.
RDA
This molecule acts as the central link connecting carbohydrate, fat, and protein metabolism.
Acetyl-CoA
This nitrogen-containing compound is the main waste product excreted in urine after protein metabolism.
Urea
This hormone stimulates lipolysis in adipose tissue during fasting or stress.
Glucagon
This metabolic cycle recycles lactate between muscle and liver.
Cori cycle
This pathway-related role of B vitamins supports energy production and nutrient metabolism.
Acting as coenzyme on metabolism
This transport mechanism moves substances from low to high concentration and requires energy (ATP).
Active transport
This enzyme, released as a zymogen from the pancreas, helps break polypeptides into smaller peptides in the small intestine.
Trypsin
This metabolic process breaks down fatty acids into acetyl-CoA units inside the mitochondria.
Beta-oxidation
This enzyme catalyzes the conversion of pyruvate to acetyl-CoA before entering the citric acid cycle.
Pyruvate dehydrogenase
This upper intake level indicates the highest daily nutrient intake that is unlikely to cause toxicity.
UL
This metabolic pathway uses oxygen to generate large amounts of ATP through a series of redox reactions in the mitochondria.
