Calcium and ATP are cofactors (nonprotein components of enzymes) required for the contraction of muscle cells. ATP supplies the energy, as described above, but what does calcium do? Calcium is ...

With longer periods of exercise our body adapts itself through changes on a molecular level. Any muscle contraction is powered through adenosine triphosphate (ATP). ATP is produced via three different ...

In skeletal muscle, mtCa²⁺ uptake, regulated by the MCU, plays a vital role in oxidative metabolism and Adenosine trisphosphate (ATP) production during contraction. Read the full story here.
