So ATP is hydrolyzed immediately and sits attached to the globular head as ADP and Phosphorous some how 'storing' the energy, even in the resting state, until flexion? I thought ATP sat there until it was hydrolyzed releasing energy to cause the flexion.
Folks are too busy obsessing over your accent to remember to thank you for the clear, concise explanation of sliding filament theory. My exam is tomorrow. I've been watching this over and over and trying to put it into my own words.
Got some errors in here though, Ca++ is released FROM the sarcoplasmic reticulum (1:10) TO the cytoplasm aka sarcoplasm, it doesn't go INTO the sarcoplasmic reticulum following an action potential. Second, influx of Ca++ into the sarcoplasm allows myosin heads to bind actin, not troponin (1:20)
Tropomyosin is covering the active actin sites. When Ca++ enters the cell, the tropomosin pulls away & exposes the active sites. Ca++ then binds to Troponin C & the myosin heads bind to the sites. Hope that helps.
hard to study when your voice is hot ;) lol thank you.

wait...so what does Calcium bind to. I thought it was troponin, but is it the binding site that tropomyosin is covering?
Yaveyta 2 years ago
Tropomyosin is covering the active actin sites. When Ca++ enters the cell, the tropomosin pulls away & exposes the active sites. Ca++ then binds to Troponin C & the myosin heads bind to the sites. Hope that helps.
ashley557512 2 years ago
yes, that helps. Thanks.
Yaveyta 2 years ago
The calcium binds to the Troponin which moves the Tropomyosin out of the way of the binding site.
