Lithotrophs _. A Use organic compounds as an energy source B Use inorganic compounds as an energy source C Use light as an energy source D Use oxidized inorganic molecules as an energy source h. The synthesis of the peptidoglycan during the growth of spherical Gram-positive bacteria occurs _______. A In patches during the B period B Across the whole cell surface during cell division C At the septum during cell division D At the septum during DNA synthesis i. Which statement is not true about FtsZ? A FtsZ polymerizes to form a Z-ring which encircles the septum. B FtsZ has a GTPase activity to hydrolyze GTP to induce a straight-to-curved conformational switch at the longitudinal interface of FtsZ to cause the constriction of the septum. C All bacteria use the FtsZ-dependent mechanism for cell division D FtsZ catalyzes the synthesis of peptidoglycan at the septum during cell division.
