Both epinephrine (a tyrosine derivative) and glucagon (a peptide hormone) increase glucose export from the liver into the bloodstream.
Each ligand binds a different receptor, but both lead to an activation of PKA. How does this happen?

B. Both receptors bind and activate the same Ga subunit, Gsa, which indirectly leads
to PKA activation.
C. Both receptors bind directly to and activate PKA after the Gsa protein dissociates
from the receptor.
D. The receptors for the two ligands interact before binding to the heterotrimeric G proteins.

Homework Origins and How Question Bank Helps
Who Invented Homework?
Homework dates back to the late 19th century, often being credited to an Italian educator named Roberto Nevilis as its creator. Nevilis introduced homework-like assignments as an extra means of reinforcing education outside school hours; although homework-type assignments existed prior to Nevilis. Indeed, ancient civilizations such as Greeks and Romans utilized similar strategies of reinforcing learning outside classroom hours. While Nevilis formalized this practice into homework as we know it today; its meaning has significantly evolved with different cultural and educational influences shaping its current meaning over time.
Does Homework Help Students Learn?
Yes, homework can be a useful tool for reinforcing what children learn in the classroom, but its efficacy is dependent on numerous things. According to research, homework that is purposeful and balanced can help students acquire crucial skills such as time management, critical thinking, and problem solving. However, excessive or badly designed schoolwork can cause stress and exhaustion. Homework works best when it is designed to reinforce key concepts, foster independent thinking, and provide opportunities for personal reflection. So, while homework can be beneficial, the trick is determining the appropriate amount and manner to help pupils learn without overwhelming them.
