The latch property of smooth muscle concerns the ability of the smooth muscle to maintain: A)A relaxed state independent of cytosolic Ca⁺⁺ level. B)Force while decreasing the rate of energy utilization. C)The rate of InsP3 production after agonist removal. D)Force in the absence of myosin light-chain phosphorylation. E)Membrane potential independent of contractile state.
