Questions & Step-by-Step Solutions

What is the function of phosphatases in cell signaling?
  • Step 1: Understand that phosphatases are a type of enzyme.
  • Step 2: Know that enzymes help speed up chemical reactions in the body.
  • Step 3: Learn that phosphatases specifically remove phosphate groups from proteins.
  • Step 4: Recognize that proteins can be activated or deactivated by adding or removing phosphate groups.
  • Step 5: Realize that when phosphatases remove phosphate groups, they deactivate certain signaling pathways in cells.
  • Step 6: Conclude that phosphatases help regulate cell signaling by turning off signals when they are no longer needed.
