Cross bridge formation between myosin heads and actin molecules is caused by the elevation of calcium ion concentration in the cytosol. during rigor mortis, this elevation of calcium ion concentration in the cytosol is permanent because stop producing atp molecules required by the sarcoplasmic reticulum's calcium ion pumpstroponin molecules bind irreversibly to calcium ions to prevent them from being removed from the cytosoltropomyosin molecules bind irreversibly to calcium ions to prevent them from being removed from the cytosolacetylcholine continues to stimulate the release of calcium ions from the sarcoplasmic reticulum

Interpret the model. a three-part model with black right-arrows between the parts. left part: a large green apple-shaped component with a w-shaped indentation centered on top. a small blue apple-slice shape sits above the left indentation and an arrow points from the shape to the indentation. a small purple apple-slice shape and arrow sit above the right indentation and an arrow points from the shape to the indentation. middle part: a large green apple-shaped component with a square indentation centered on top. sitting in the left side of the indentation is a blue apple-slice shape with a flat bottom, fused to a purple apple-slice shape with a flat bottom on the right side of the indentation. right part: a large green apple-shaped component with a w-shaped indentation centered on top. an up-arrow is centered above the indentation pointing to a fused blue and purple apple-slice-shaped flat-bottom component sitting above the indentation. assigne "true" or "false" to the end of each statement. the model shows a shape change occurring in the enzyme after the substrate is bound in the active site. t/fthere are two products in this model. t? f there are three substrates in this model. t/f the model shows two different enzymes. t/f
