The binding of subunits causes hydrolysis of ATP (actin) or GTP (microtubules) and decreases the

strength of binding causing... - Answer✔✔-Dynamic instability


Which end do the ATP/ GTP molecules dissociate from? - Answer✔✔-Minus end


What provides a stronger, stable actin structure? - Answer✔✔-Bundling proteins together


What regulates shape and number of actin filaments and microtubules through altering the number of

regulatory proteins? - Answer✔✔-Nucleus


What acts as a scaffold for myosin (motor protein) in muscle cells and helps with vesicle movements? -

Answer✔✔-Actin filaments


What are apical cell membrane projections that increase SA? - Answer✔✔-Microvilli


What are microvilli supported by? - Answer✔✔-Actin bundles- in the core and anchored to terminal web

of actin at the base


What produces cellular contraction (and cellular movement) by sliding actin filaments in opposite

directions and hydrolyzing ATP in the process? - Answer✔✔-Myosin


What are the 4 main functions of microtubules in the cell? - Answer✔✔-Mitotic spindle, cilia and

flagella, anchor organelles, motor proteins (dynein and kinesin) move vesicles along


What are the sites that localize microtubule minus ends? - Answer✔✔-Microtubule organizing centers

(MTOC)


What is used by all cells for generating the mitotic spindle during mitosis and meiosis? - Answer✔✔-

Centrosome
