Packet 10: Tossup 10

One part of these structures in Gram-negative bacteria is composed of the (-5[1])L, P, (-5[1])MS, (-5[1])and (-5[1])C rings. (-5[1])Fli proteins allow these (-5[1])structures to change directions, and (15[1])Mot proteins move these structures (15[4])with a proton gradient. A type (-5[1])of these structures can cause cells to “tumble.” (15[1])That (15[1])“peritrichous” (15[1])type of these structures (15[1])are attached in all directions. (0[1])By definition, (-5[2])(*) Opthisokonts possess these structures. These structures (10[1])are composed of a “hook,” “motor,” and “filament.” (10[9]-5[1])They’re (10[1])not cilia, (10[1])but (10[1])these (-5[1])structures (10[2])possess a (10[1])9+2 (10[2])arrangement. For 10 points, (10[1])name these tail-like structures that provide (10[1])motility to some types of bacteria. (10[2])■END■ (10[5]0[2])
