The muscle pulls on the bones it is connected to resulting in movement.]]> 2023-01-31 14:49:43 UTC https://padlet.com/martha_garrels/9war9gaioylg08av/wish/2463115379 https://padlet.com/martha_garrels/9war9gaioylg08av/wish/2463117890 I think that the actin connects to the myosin and completes the "power stroke" so they are directly parallel to each other.]]> 2023-01-31 14:50:59 UTC https://padlet.com/martha_garrels/9war9gaioylg08av/wish/2463117890 https://padlet.com/martha_garrels/9war9gaioylg08av/wish/2463118420 I think that the actin and the myosin glide past each other, creating a power stroke. ]]> 2023-01-31 14:51:16 UTC https://padlet.com/martha_garrels/9war9gaioylg08av/wish/2463118420 https://padlet.com/martha_garrels/9war9gaioylg08av/wish/2463120228 The actin pulls the myosin in a sliding filament while the energy shape changes myosin so it can bind and complete "The Power Stroke". ]]> 2023-01-31 14:52:17 UTC https://padlet.com/martha_garrels/9war9gaioylg08av/wish/2463120228 https://padlet.com/martha_garrels/9war9gaioylg08av/wish/2463129500 I think that the myosin binds to the actin so that the myosin pulls the actin, completing "The Power Stroke."
