Ch 25: Nutrition, Metabolism, and Temp Flashcards
Nutrients
Produce energy
Essential nutrients
Must be ingested, can’t be synthesized by the body
Non essential nutrients
Can be synthesized by the body
Carbohydrates
- monosaccharides: 1 glucose/ fructose
- disaccharides: 2 or more sucrose
- polysaccharides: many
Where can glucose be stored
Liver and muscle as glycogen
Lipids
Triglycerides and fatty acids
Fat soluble
Vitamins A,D,E,K
Water soluble
Vitamins B and C
Metabolism
Catabolism + anabolism
Catabolism
Energy releasing process or large molecules broken down into smaller
Anibolism
Energy requiring process or small molecules joined to form larger molecules
Process of ATP production
Carbs, glycolysis, pyruvic acid, Kebs cycle, electron transport chain
Glycolysis
Occurs in the cytoplasm
2 units of 3 carbons
Pyruvic acid
Oxidized and turns to acetylcholine-CoA
Krebs cycle
Produces ATP NADH, FADH2, CO2
Occurs in the matrix of mitochondria
Electron transport system
Produces atp
Glycolysis process
Location- cytoplasm
Start material- glucose
End material- 2 units of 3 carbs each—>
( pyruvic acid)
Does the Krebs cycle only have FADH2
True
What systems produce NADH
Glycolysis, pyruvic acids, Krebs cycle
What is the matrix of mitochondria
Deeper membrane
What does the Krebs cycle produce
Both NADH and FADH2
What does the Cole trim transport chain produce
32 ATP from the oxidation phosphorylation
Can pyruvic acid enter in Krebs cycle
False, it’s Acetyl-CoA
Which complex makes NADH
1st complex, then it bounces off other complexes and will pull other H+ Ions
Which complex form FADH2 molecule
Punks 2H+, 2 ATP
Which complex’s pump H+
Complex 1,3,4
What happens in Complex 4
Oxidation occurs
ATP Synthase
Enzyme that produces ATP molecule for every H+
What is the LDL equation
LDL= TC-HDL-(TG/5)
Units: mg/dL
