Explanation / Answer

15. D) GTP hydrolysis

Explanation: Movement of kinesin along microtubules is powered by hydrolysis of ATP. Dyneins move along the opposite/ negative end of the microtubules.

16. B) The extracellular matrix consists of collagen and fibroblasts

Explanation: The extracellular matrix consists of ground substance and protein fibres.
