Overview Of Metabolism Flashcards
What are the major functions of metabolism
Storage for energy
Transforming molecules
Eliminating byproducts
Metabolic pathways
Catabolism = breakdown, releases energy in the process
Anabolism = synthesizes, needs energy input
Forms of chemical energy
ATP
NADPH - common redox agent/e- donor
NADH - makes ATP
NADPH - for biosynthesis
ATP is the unit of energy generated by the _____ of fuels (like glucose, AAs, FAs)
Oxidation
Oxidation of glucose, FAs, AAs lead to
Acetyl CoA
NADH vs NADPH
NADH = carries e- to ETC
NADPH = carries e- for biosythesis
NADH and NADPH are used for
Anabolism
NAD+ and NADP+ are used for
catabolism
What is the organ that carries out the major pathways
LIVER
What molecules are the key links between metabolic pathways
Glucoee 6 phosphate (G6P)
Pyruvate
Acetyl-CoA
Fuels consumed by humans
Carbs(glucose)
Fat(FA)
Proteins(AA)
Fuels are oxidized to ____ and this is oxidized completely to ____
Acetyl CoA
CO2
The most ___ bond in ATP is the
Distal
Highest energy
What happens when bonds are broken
Release energy
Mitochondria recharge
ADP to ATP
High energy compounds
Phosphoenolpyruvate
Carbamoyl phosphate
1,3bisphosphoglycerate
Creative phosphate
What requires energy and what are the forms
Mechanical = muscle contraction
Thermogenesis = shiver
Ion transport = Na+/K+ pump (needs ATP)
Detoxification = Liver and Kidney
Biochemical/biosynthetic = protein sythesis
And termination of RNA transcription
Which organs are maintainers
Liver
Adipose
Which organs are consumers
Brain
Skeletal muscle
Which organs are excretory
Kidneys
Lungs - get rid of VOLATILE CO2
