Answer 1

CheY-P binds to a specific substance in bacterial chemotaxis

Step-by-step explanation:

CheY-P binds to a specific substance. CheY is a protein involved in bacterial chemotaxis, which is the movement of bacteria in response to changes in chemical gradients. When CheY is phosphorylated (CheY-P), it undergoes a conformational change that allows it to bind to the flagellar motor protein, resulting in a change in the direction of flagellar rotation.

CheY-P (phosphorylated CheY) is a response regulator protein involved in bacterial chemotaxis. In the context of chemotaxis, CheY-P binds to the bacterial flagellar motor switch complex. The binding of CheY-P to the switch complex induces a conformational change that leads to a change in the direction of flagellar rotation, allowing the bacterium to move towards or away from chemical stimuli in its environment. This process is a key mechanism by which bacteria can navigate and respond to changes in their surroundings.
