Notes + Study Questions Of Metabolism Flashcards
What are 3 major metabolic destinations for principal nutrients
active processes
synthesized into structural or functional molecules
synthesized as fat or glycogen for later use as energy
What are the locations of events of cellular respiration
Glycolysis: cytoplasm
Krebs Cycle: mitochondrial space
ETC: inner-mitochondrial membrane
What is the equation of aerobic cellular respiration
C6H12O6 + 6 O2 = 36-38 ATP + 6 CO2 + 6 H2O
End creation of Glycolysis
2 pyruvic acid
2 ATP
2 NADH
End creation of Transitional step (pyruvic acid decarboxylation)
2 Acetly CoA
2 CO2
2 NADH
End creation of Krebs Cycle
2 ATP
4 CO2
6 NADH
2 FADH2
End creation of ETC
36-38 ATP
6 CO2
6 H2O
What are the 6 main types of nutrients
water
carbohydrates
lipids
proteins
minerals
vitamins
The function of Vit A
needed to make the visual pigment retinal
The function of Vit D
needed for calcium absorption
The function of Vit K
needed to help with clotting
The function of Vit C
needed for proper growth of CT
The function of Vit B3
a precursor for NAD, which plays essential metabolic roles in living cells
The function of Vit B1
needed for neural function & carbohydrate metabolism
The function of Vit B9
needed to synthesize the bases used to replicate DNA
The function of Vit B12
needed for normal nerve function & for the formation of blood
What is the difference b/w glycogenesis and glycogenolysis
Glycogenesis = conversion of glucose to glycogen; occurs in the liver & stimulated by insulin
Glycogenolysis = conversion of glycogen to glucose; occurs b/w meals & stimulated by glucagon & epinephrine
what are the 4 classes of lipoproteins
1) chylomicrons - contain dietary lipids
2) very low density lipoproteins - contain endogenous triglycerides
3) low density lipoproteins - 75% total body cholesterol
4) high density lipoproteins - remove excess cholesterol
what are the 3 things that amino acids can be converted into
glucose, fatty acids, and ketone bodies
