Bacterial Shape is Determined By

Question

Bacterial shape is determined by
A) tubulin and actin.
B) cell membrane.
C) cytoskeleton.
D) S-layers.
E) a protein called crescentin.

Accepted Answer

Bacterial shape is primarily determined by the cytoskeleton, which includes proteins such as FtsZ, MreB, and CreS. These proteins provide structural support and help to maintain the shape of the cell. While the cell membrane and S-layers may play a role in maintaining the shape, they are not the primary determinants. Tubulin and actin are found in eukaryotic cells, not bacteria. Crescentin is a protein found in some bacteria, such as Caulobacter crescentus, but it is not present in all bacterial species and is not the primary determinant of shape in bacteria.
