In the example of adrenaline signaling used in the animation, suppose each amplification step produces hundredfold active molecules. How many total modified protein target molecules result from a single activated signal receptor? A. 300 B. 900 C. 10,000 D. 1,000,000 E. 100,000,000

D. 1000000

Explanation:

Adrenaline signaling occurs when the the hormones clings to the cell surface of the Adrenaline receptor.

The total modified protein target molecules resulting from a single activated signal receptor is 1,000,000 and this results in the consumption of 100 molecules of Guanosine triphosphate (GTP) and 1,010,000 molecules of Adenosine triphosphate (ATP).
