Solution for QID #90455: Could you help me answer this question? Thank you You | StudyHelpMe

Could you help me answer this question? Thank you   You are learning the terminology of muscle microstructure and function. Words like sarcolemma, sarcoplasm, sarcomere, myofibril, myosin, actin, A band, I band, Z-membrane, H-zone, M-line, T-tubule, etc. are no longer like a foreign language to you (hopefully)! Given your familiarity with this collage of terms, provide the basic function of the T-tubules.   A) They conduct the wave of depolarization from the muscle fiber membrane to the myofibril; B) They release calcium ions into the sarcoplasm during depolarization of the muscle cell; C) They release ATP into the cisternae of the sarcoplasmic reticulum; D. They are primarily conduits for calcium ions; E. They pump calcium ions back into the sarcoplasmic reticulum from the sarcoplasm.   Please explain why the answer is correct and why the remaining choices are incorrect
