Question

Discuss the molecular basis of skeletal muscle contraction

Answer 1

Muscle contraction happens only when the energy molecule called adenosine triphosphate (ATP) is present. ATP has three phosphate groups that it can give away, releasing energy each time. Myosin is the motor protein that does muscle contraction by pulling on actin rods (filaments) in muscle cells.

Answer 2

➡The molecular basis of muscle contraction. Muscles contract by the interdigitation of protein filaments within them. These filaments are made up of myosin and actin molecules. ... Sliding of rhodamine labelled actin over myosin thick filaments in the presence of the Cy3-EDA-ATP.
