Explanation:
Detailed explanation-1: -Substrates can be quickly carried to the center of the muscle fiber where there are proteins to transport glucose (and presumably other substrates) across the T-tubule membrane to the site where it can be immediately utilized or stored.
Detailed explanation-2: -T-tubules are invaginations of the plasma membrane, which are present exclusively in striated muscle. Their role is to maintain the SR calcium store under the tight control of membrane depolarization via the voltage sensor channel DHPR [2].
