How do muscle cells access what they need to keep producing energy
Ganezh [65]

Muscle cells access what they need to continue producing energy through chemical energy from ATP to transform it into mechanical energy.  

Muscle cells are elongated cells whose length can reach several centimeters.  

The muscle uses ATP (energy) to carry out conformational changes in its molecular structure => variation in the length of the sarcomere.  

Adenosine triphosphate (ATP) is the basic source of energy for muscle contraction.  

Each link stores 7300 calories of energy per mole of ATP under normal conditions and when a phosphate radical is separated from the molecule, these calories are available providing the energy necessary for muscle contraction.  

The muscle cell has three mechanisms to resynthesize ATP:  

  • ATP synthesis through phosphocreatine.  

  • Anaerobic glycolysis process with the transformation of muscle glycogen into lactate.  

  • From oxidative phosphorylation.  

ATP synthesis through phosphocreatine consists of the transfer of energy from phosphocreatine to ADP so that it can reincorporate a phosphate group to its molecule and transform it into ATP.

So the energy that has been released in the hydrolysis of PCr is directly used to resynthesize ATP from ADP.  

Therefore, we can conclude that muscle cells access what they need to continue producing energy through the chemical energy of ATP to transform it into mechanical energy.
