Answer #1

The role of ATP is when ATP hydrolysis it give free energy to cross bridge which causes force and when ATP bind to Myosin further dissociation of cross bridge and begins of new cycle

Role of calcium in skeletal muscle contraction is when calcium bind to troponin it change into tropomyosin

Sarcoplasmic reticulum stores which release when any muscle cell is stimulated

The role of sodium in skeletal muscle contraction is kt allows to influx of sodium into cytoplasm of muscle fibers and sodium flux send messages to activated muscle fibers which stores calcium

ATP AND MYOSIN

ATP prepared myosin for binding of higher energy state ehihx further MYOSIN forms the cross bridge with actin

ATP provide energy to muscle for contraction and myosin will bind to form bridge and activates the other change ions to flow

Place the following events in the correct order they occur during excitation-contraction coupling in skeletal muscle: Myosin forms a tight bond with actin and undergoes the ‘power stroke’. The troponin/tropomyosin complex shifts, exposing the myosin binding sites on the actin filament. Ca2+ binds to troponin. Ca2+ moves out of the sarcoplasmic reticulum (called a “calcium spark”). An action potential in the alpha motor neuron leads to the release of neurotransmitter at the neuromuscular junction. Nicotinic receptors on the motor end...

1. When an action potential reaches the T-tubule, it will activate the dihydropyridine receptor at the T-tubule to change conformational shape. Dihydropyridine receptor will trigger ryanodine receptor channel to secrete Ca2+ from the sarcoplasmic reticulum into the cytosol. When action potential is absent, Ca2+ ATPase at the sarcoplasmic reticulum will pump cytosolic Ca2+ into the sarcoplasmic reticulum. Select one: a. True b. False 2. What is TRUE about the myofibril? Select one: a. The thick and thin filaments on the...
