Explanation / Answer

15. A dynamic behavior called polymerization occurs on microfilaments and microtubules when net assembly at the positive end is offset by net disassembly at the negative end. 18. Although microtubules can undergo both treadmilling and dynamic instability, inside the cell they typically exhibit dynamic instability since their minus ends are embedded in cytoskeleton. 20. Two events that consume large quantities of ATP during muscle contraction are a) ATP binding myosin b) myosin then hydrolyzes the ATP
