(1) Likely found in an autotroph - carboxysomes
(2) H antigen - flagellum
(3) Counterclockwise rotation of flagella/flagellum - produces “runs” towards an attractant
(4) PHB granule – glycogen storage
Step-by-step explanation:
Autotrophic bacteria contain microcompartments called carboxysomes. These are protein subunits containing enzymes which involve in carbon dioxide concentration or fixation mechanism.
H antigen is the protein found in the thread-like slender filaments of the flagella.
Counterclockwise rotation of the flagella produces “runs” or a swimming movement which facilitates bacterial walk or movement.
PHB – photohydroxybutyrate molecules are the biopolymers produced by bacteria when carbon nutrients like glycogen granules are available in excess and convert them to carbon storage reserves.
