yes E weldone
A Cardiac muscle does not have actin and myosin organized into sarcomers. Cardiac muscle does have sarcomers, and they determine the Frank-Starling mechanism.
B Red muscle fibers have a large mass per motor unit. Red muscle fibers have a small mass per motor unit because they typically belong to muscles that do not require less power.
C Skeletal cells have limited sarcoplasmic reticulum. These muscle fibers typically have extensive sarcoplasmic reticulum because the calcium needs to bind to troponin to activate the muscle fiber.
D Smooth muscles have high ATPase activity. Smooth muscles have low ATPase activity. Cardiac and skeletal muscles have a higher ATPase activity because they are involved in more rigorous work.
E White muscles have a high capacity for anaerobic glycolysis. White muscles have a high capacity because they are used as large, powerful muscles in short-term bursts of activity
