Force lags behind the Ca²⁺ transient because A) Myofilament activation is slow B) It takes time for the active myofilaments to stretch the series elastic elements C) Ca²⁺ binding to TnC is slow D) Ca²⁺ diffusion to TnC is slow E) Ca²⁺ release by RyR is slow

Question

Quizplus · Accepted Answer

It takes time for the active myofilaments to stretch the series elastic elements, which explains the delay in force development following the transient increase in calcium concentration. This stretching of elastic components within the muscle fiber contributes to the time lag before force is observed.
