Proteins are the macromolecules that make up both microtubules and microfilaments.

Explanation:

Microtubules and microfilaments are involved in making cytoskeletal fabric of the cell.

#(A)# Microtubules are made up of tubulin protein. These are long and unbranched slender tubulin protein structures and their important role is in the assembly and disassembly of spindle structures during mitosis.

#(B)# microfilaments are made up of contractile protein i.e actin. These are considerably more slender than microfilaments. And are mainly involved in internal cell motion.
