Metabolism and Energetics Flashcards
refers to all the chemical reactions that occur in an organism
metabolism
provide the energy needed to maintain homeostasis and to perform essential functions
cellular metabolism
the breakdown of organic substrates in the body
catabolism
the synthesis of new organic molecules
anabolism
the drive to seek food and stimulates cells to take up glucose and adipocytes
appetite
hormone that controls appetite
insulin
stimulated when you eat; puts off adipocytes to suppress your appetite
leptin
helps enhance appetite
neuropeptide y
comes from stomach; activate neuropeptide
ghrelin
a complex carbohydrate found in plants that is not digestible in humans
cellulose
name the fat-soluble vitamins
- vitamin a
- vitamin d
- vitamin e
- vitamin k
a process of amino acid catabolism where the amino group is removed and an ammonium ion is released
deamination
fat-soluble vitamin that maintains epithelia; required for synthesis of visual pigments; supports immune system; promotes growth and bone remodeling
vitamin a
fat-soluble vitamin that is required for normal bone growth, intestinal calcium and phosphorus absorption, and retention of these ions at the kidneys
vitamin d
fat-soluble vitamin that prevents breakdown of vitamin a and fatty acids
vitamin e
fat-soluble vitamin that is essential for liver synthesis of prothrombin and other clotting factors
vitamin k
vitamins that are absorbed primarily from the digestive tract along with the lipid contents of micelles; carried in lipids and resistant to heat
fat-soluble vitamins
oxidize carbohydrates
thiamine
oxidize glucose
riboflavin
oxidize glucose, synthesis of proteins and fats, formed NAD in cellular respiration
niacin
part of coenzyme A, makes acetyl CoA for CAC
panthothenic acid
coenzyme in amino acid and lipid metabolism
pyridoxine
metabolism of amino acid, fatty acids, and synthesis of nucleic acid
biotin
metabolism of amino acids and nucleic acids; rbc production
folacin
synthesis of nucleic acid . metabolism of carbs and fats, rbc production
cyanocobalamin
known as ascorbic acid, chemically related to monosaccharides, collagen production, iron absorption
vitamin c
inorganic elements from plants and has a vital role in many metabolic processes
minerals
