ATP & Muscle Contraction

Question 1

What happens during creatine phosphate in ATP and muscle contraction?

Answer 1

phosphate group is added to ADP to make ATP
cells store creatine phosphate for energy
short and simple reaction = fastest way to make ATP
CP stores used up quickly - used for high intensity and short duration e.g. power lifting
anaerobic
alactic - doesnt make lactic acid

Question 2

What is anaerobic respiration used in ATP and muscle contraction?

Answer 2

2 ATP made by glycolysis
pyrunate makes lactate which causes muscle fatigue
short duration, high intensity e.g. 200m

Question 3

What is aerobic respiration in ATP and muscle contraction?

Answer 3

lots of ATP mostly by oxidative phosphorylation

slow = many reactions - no harmful waste products
