What is NADH used for?

electrons from breakdown/catabolism to the ETC (electron transport chain)

1

what is NADPH used for?

electrons for biosynthesis/anabolism

2

what organ can carry out all major metabolic functions?

Liver

3

What are the key links between all the metabolic pathways?

Glucose 6 P
Pyruvate
Acetyl CoA

4

What are the energy currencies of the body? What is their function?

ATP/ GTP are most high energy
Glutathione
BH4
Cytochrome c
NADH
NADPH

They function to provide electrons

5

What is the irreversible commitment of pyruvate? what is the product?

Decarboxylation to Acetyl CoA

alpha-linoleic
alpha-linolenic

9

What are the essential fatty acids from fish oils?

EPA
DHA

10

What is DEE?

daily energy expenditure
equal to basal metabolic rate + physical activity+ diet induced thermogenesis

11

What is BMR?

basal metabolic rate
calculated at rest/asleep

12

What is the primary determinant of metabolism?

FFM - fat free mass

13

What is RMR?

Resting Metabolic rate
calculated at rest/awake

14

what is BMI?

body mass index
weight/height^2

15

xerophthalmia

vit A deficiency
Nightblindness

16

what is metabolism?

oxidation of reduced fuel (glucose) to generate energy in the form of ATP and NADPH/NADH
