In this video Paul Andersen explains how you can drive non spontaneous processes by adding external energy (like electricity or light) or by coupling it to a spontaneous process (like the conversion of ATP to ADP)
Do you speak another language? Help me translate my videos:

College, OpenStax. English: (a) The Active Site on Actin Is Exposed as Calcium Binds to Troponin. (b) The Myosin Head Is Attracted to Actin, and Myosin Binds Actin at Its Actin-Binding Site, Forming the Cross-Bridge. (c) During the Power Stroke, the Phosphate Generated in the Previous Contraction Cycle Is Released. This Results in the Myosin Head Pivoting toward the Center of the Sarcomere, after Which the Attached ADP and Phosphate Group Are Released. (d) A New Molecule of ATP Attaches to the Myosin Head, Causing the Cross-Bridge to Detach. (e) The Myosin Head Hydrolyzes ATP to ADP and Phosphate, Which Returns the Myosin to the Cocked Position., April 3, 2013.
