Signal Transduction.

Question 1

What are the 3 steps of signal transduction?

Answer 1

1-reception / 2- transduction / 3- cell responds

Question 2

What happens when the chemical signal is weak?

Answer 2

Intermediate proteins can amplify the message and communicate it to more proteins in transduction.

Question 3

Which step?: signaling molecule contact at a location on a specific membrane protein which changes the protein’s shape.

Answer 3

Reception.

Question 4

Which step?: 1-catalyzing an enzyme to speed up the chemical reaction/ 2- altering the cytoskeleton to change shape./ 3- activating a gene to direct protein synthesis of another substance.

Answer 4

Cell response

Question 5

Identify the methods by which the plant cell responds when stimulated by a stimulus?

Answer 5

1- catalyzing an enzyme to speed up a chemical reaction./ 2- activating a gene to direct protein synthesis./ 3- altering the cytoskeleton to change shape.

Question 6

Which step?: a receptor protein sends chemical signals to other protein in the cytosol to either accept and transmit or reject the message. If the chemical reaction is weak the intermediate proteins can amplify the message and communicate it to more proteins.

Answer 6

Transduction.
