unit 1.8 energy systems in muscle cells

Question 1

lactate metabolism

Answer 1

if don’t get enough O2 to support electron transport chain then pyruvate in converted to lactate

Question 2

where does lactate diffuse from

Answer 2

its diffuses from the muscle to blood stream taken up by liver

Question 3

oxygen debt is

Answer 3

allow respiration provide energy to convert lactate to pyruvate and glucose in liver

Question 4

types of skeletal muscle fibres

Answer 4

slow twitched
fast twitched

Question 5

slow twitch

Answer 5

slow contraction
over long period of time
fats are there fuel
many mitochondria
generate ATP through aerobic
large blood supply
long distance running

Question 6

fast twitch

Answer 6

fast contractions
over short period of time
glycogen are their fuel
fewer mitochondria
generate ATP from glycolysis
lower blood supply
sprinting
