Flashcards in  Class 5- Theisen Fundametal Of Nutrition Deck (141)
What form(s) of metabolism occur(s) in the cytosol?
Pentose phosphate pathway
Fatty acid synthesis
What form(s) of metabolism occur(s) in the mitochondrial matrix?
ß-oxidation of FAs
Ketone body formation
What form(s) of metabolism occur(s) in the interplay between both cytosol and mitochondrial matrix:
7 forms of metabolism:
Citric acid cycle
What organ can carry out all of the reactions in the major pathways?
3 key points in metabolism:
3 major elements of energy in body/foodstuff?
Sugars, proteins, lipids
What dictates insulin/glucagon response or BG detection?
Central component to all of metabolism
Carbohydrates and protein are both 4 kcal/g. So, if you eat the same amount, there is no difference in energy consumed, right?
No, there is a difference because of the different pathways the food req's for breakdown..different amt's of energy are required to break down either
In what form does the body provide energy for the metabolism [breaking down] and catabolism [forming] of biomolecules?
In the form of ATP
Biomolecules built from AA's
Critically important in cell life
3 functions of proteins:
Fuel supply[TCA cycle->ATP production]
Structural support [elastin,keratin]
Where can several AA's be found in metabolism
Nitrogen-containing carboxylic acids
Proteinogenic AAs Serve as basic building blocks of peptides and proteins
AA function as precursors of biologically important molecules:
-acetyl CoA, heme, melanin, amines, hormones(insulin/glucagon)
What kind of amino acids are required for maintaining health?
What is an effect of not consuming enough essential AA's?
Negative nitrogen balance
Made up of C,H,O (3-9C[H2O])
Important fuel stores
Critical molecules control of human metabolism- catabolic
Carbon skeletons used for synthesis of the other important biomolecules-anabolic
4 common dietary carbohydrates:
The nutritional reservoir in CH of plants
Polysaccharide of glucose
Amylose and amylopectin
The unbranched glucose polysaccharide in plants
The branched glucose polysaccharide in plants
The natural sweetener and found in fruits and vegetables
Disaccharide of glucose and fructose
Plant origin carbohydrate
The major dietary carbohydrates of animal origin
Disaccharide of glucose and galactose
This condition is d.t the body's inability to easily digest lactose [gas,belly pain, bloating]
Simplest form of carbohydrates?
Ex of monosaccharide:
Glucose, fructose, galactose, ribose
