When you die, your body is initially floppy and flexible

Subject:BiologyPrice: Bought3

When you die, your body is initially floppy and flexible. Considering the sliding filament theory, explain if: 

1) the myosin head is inside or outside the actin binding site. 

2) If the regulatory proteins are covering the binding site away from the binding site. 

3) Is calcium being held in the sarcomere binding site or in the sarcoplasmic reticulum? 

4) Did the sarcoplasmic reticulum release or not release?

 

When you die, rigor mortis sets in and the body is stiff and muscles are contracted. Considering the sliding filament theory, explain if: 

1) the myosin head is inside or outside the actin binding site. 

2) If the regulatory proteins are covering the binding site away from the binding site. 

3) Is calcium being held in the sarcomere binding site or in the sarcoplasmic reticulum? 

4) Did the sarcoplasmic reticulum release or not release?

 

When you die after rigor mortis sets in your body goes back to the initial flexible and floppy state. Considering the sliding filament theory, explain if: 

1) the myosin head is inside or outside the actin binding site. 

2) If the regulatory proteins are covering the binding site away from the binding site. 

3) Is calcium being held in the sarcomere binding site or in the sarcoplasmic reticulum? 

4) Did the sarcoplasmic reticulum release or not release?
