Introduction to metabolism

Question 1

Phosphocreatine

Answer 1

short term energy store

Question 2

AMP

Answer 2

marker low energy status

Question 3

Pyruvate aerobically

Answer 3

36ATP

Question 4

RBCs

Answer 4

energy from anaerobic glycolysis

Question 5

Cardiac muscle

Answer 5

lots myoglobin (high affinity O2)–> highly aerobic

Question 6

Skeletal muscle type 1

Answer 6

highly aerobic
prolonged modest activity
FA

Question 7

Skeletal muscle type 2b

Answer 7

explosive action
few mitochondria
no myoglobin –> white
phosphocreatine–> rapid replenshment ATP
relies on anaerobic glycolysis: glucose from glycogen store
adrenaline or insulin–> glucose uptake

Question 8

Skeletal muscle type 2a

Answer 8

some mitochondria and myoglobin 
maintains aerobic where possible 
Phosphocreatine + glucose= energy store 
adrenaline/insulin --> glucose uptake
lower energy levels--> FFA energy source
Fasting--> release AA for gluconeogenesis

Question 9

Diabetes

Answer 9

extra glucose –> increase circulating volume –> increase BP and decrease O2 levels
