Within the cytoplasm of cells, there is an extensive network of protein fibres. This is known as the cytoskeleton. The cytoskeleton is made up of two main types of protein fibres: microfilaments and microtubules. Microfilaments are solid strands that are mostly made of the protein actin.
Question. When proteins move cargo throughout the cell, they do so via the [blank_start]microtubules [blank_end] of the cytoskeleton. These proteins are composed of double [blank_start]helices [blank_end] which allow roation. Each 'head' can attach to the microtubule when bound to [blank_start]ATP [blank_end].
