Sodium channels open up, which caused Na to flow, this is called depolarization. This causes ATP that moves along the sarcolemma. Repolarization occurs when the K channels open up. The potassium starts to flow across the sarcolemma. ]]> 2019-03-11 12:43:55 UTC https://padlet.com/nonnir123/ch1gu8n98y1b/wish/339914476 Event 2: EC Coupling nonnir123 https://padlet.com/nonnir123/ch1gu8n98y1b/wish/339914523 Step 1:  ATP is going down the sarcolemma and the T tubule

It also takes away blocking action of tropomyosin by the change of actin in shape. This allows myosin to be exposed. Then myosin binds to actin making a cross
