Release myosin from actin active sites. and To cause myosin to change shape to the cocked (extended) position.

Fatty acids and glucose can be utilized by muscle cells for aerobic respiration.Muscle cells use ATP for two things:active calcium (Ca++) transport and motor protein movement Creatine phosphate transfers its phosphate back to ADP to form ATP and creatine when the muscle begins to contract and requires energy.The enzyme creatine kinase is the catalyst for this rapid reaction;Consequently, ATP derived from creatine phosphate powers the first few seconds of muscle contraction.One glucose molecule has enough energy to make 38 ATP in the presence of oxygen.

The glycolysis preparatory phase yields -2 ATP, the glycolysis pay-off phase yields 7-9 ATP, the oxidative decarboxylation of pyruvate yields 5 ATP, and the Krebs cycle yields 20 ATP.The culmination of each of the aforementioned processes was one glucose, which has 38 ATP.The cellular function of cellular respiration drives all of these processes.

DISCLAIMER:The question is incomplete.

What two roles does atp play during the contraction stage? choose all that apply.

  • Release myosin from actin active sites.
  • To cause myosin to change shape to the cocked (extended) position.
  • At rest, the H-band is about half the lengh of the A-band
