Multiple choice

Methyl-accepting chemotaxis proteins of bacteria ________.

  1. help to guide the bacterium since they are directly connected to the flagellar motor

  2. can only sense conditions that are favorable for bacterial growth

  3. tell the bacterium which way to go

  4. integrate multiple signals through a two component phospho-relay system

D Correct answer
Explanation

Integrate multiple signals through a two component phospho-relay system. The methyl-accepting chemotaxis proteins are present on the outer surface of the bacteria. They are chemical sensors that help the bacteria to sense components present in its surroundings.
