Cell Signaling

Question 1

Explain how a cell signaling molecule can lead to a response in a cell

Answer 1

• cell signaling molecule binds to the receptor
• cell signaling molecule is complementary to the receptors
• this triggers secondary messenger which activates the enzymes

Question 2

How does fatty acids exit the cell

Answer 2

Via facilitated diffusion
Passively, from high to low concentration down the diffusion gradient
They travel through Chanel proteins

Question 3

Process of cell signaling

Answer 3

• hormones release into blood stream
  Hormone is the cell signaling molecule
  Named target cell
  Hormone binds to the receptor
  Receptor is complementary to the hormone
  Cascade of reactions occur
  A response is produced
