The bacterial cytoskeletal proteins ftsz and mreb are homologous to the eukaryotic and respectively.

Tubulin, actin.

Explanation:

Cytoskeleton may be defined as the network of protein filaments present in the cytosol of the organism. Cytoskeleton helps in the movement of cell organelle and their interaction with other organelles.

MreB protein is a cytoskeletal protein present in bacteria that control the width shape of the rod shaped bacteria. The MreB protein is homologous to the actin protein of bacteria because of the similarity in their peptide sequence and tertiary structure. FtsZ is the cytoskeletal protein present in bacteria that helps in the cell division. The FtsZ protein is homologous to tubulin protein of eukaryotes because of similarity in their function.

Thus, the answer is tubulin, actin.

lysosome is this part of the cell is surrounded by a very thick outer membrane to protect the rest of the cell from its strong enzymes.
