Q

What happens when attractants bind to the MCP

A

inhibits autophoshorylation of CheA. The filament will rotate CCW and cell will run

Q

What happens if no attractant is bound to the MCP

A

CheA will autophosphorylate then CheA-P will phophorylate CheY. CheY-P will interact w.FliM. filament will turn CW and cell tumbles
