Question
Which of the following statements about bacterial motility is TRUE? Choose all the correct statements. Group of answer choicesGliding motility independent of flagella is seen in some cyanobacteriaCilia composed of microtubules are responsible for movement in many groups of bacteriaBacterial flagella rotate to propel the bacteria through a liquid medium.An ATPase releases energy from ATP to drive rotation of bacterial flagella
Solution
-
"Gliding motility independent of flagella is seen in some cyanobacteria" - This statement is TRUE. Some cyanobacteria do exhibit a type of movement known as gliding motility, which does not rely on flagella.
-
"Cilia composed of microtubules are responsible for movement in many groups of bacteria" - This statement is FALSE. Bacteria do not have cilia. Cilia are found in eukaryotic cells, not in bacteria which are prokaryotic.
-
"Bacterial flagella rotate to propel the bacteria through a liquid medium" - This statement is TRUE. Bacterial flagella do rotate, and this rotation propels the bacteria through liquid mediums.
-
"An ATPase releases energy from ATP to drive rotation of bacterial flagella" - This statement is FALSE. The rotation of bacterial flagella is powered by a flow of protons (H+ ions), not ATPase. The energy for flagellar rotation comes from the proton motive force, not ATP hydrolysis.
