CAMP (cyclic adenosine monophosphate) is a molecule that can activate kinase enzymes allosterically in the cytoplasm. Describe the effects of CAMP molecules on kinase enzymes.
In Figure 4C, we see the inhibition of LRRK2 kinase activity by nanobody 1 (Nb1). Using the Lineweaver-Burke plot, estimate the Km of LRRK2 in the absence of Nb1. Show your work and provide your answer with the correct units.
Ras uses proteins called ___________________ proteins. These proteins bridge the receptor and Ras (small monomeric G-protein) and induce Ras to release GDP and bind GTP which makes the Ras active. Active Ras can initiate a kinase cascade.
The Luteinizing hormone receptor (LHR) is a GPCR that predominantly couples to Gαs (G alpha s) G proteins in response to binding of the endogenous ligand luteinizing hormone (LH). Briefly describe how activation of this receptor ultimately leads to protein kinase A (PKA) activation.

added ligand concentration of 10 µM is 5 × 10³ s¹. What is the value of the reverse rate constant k_1 = 1 ×10-4 Incorrect Macmillan Learning You have not correctly calculated the value of the reverse rate constant. To begin, calculate the value of k₁ by dividing the rate of receptor-ligand complex formation (the rate of the forward reaction) by the ligand concentration. k₁ = rate forward [L] Then, calculate the value of the reverse rate constant, k_₁, by multiplying the dissociation constant, Kd, and the forward rate constant, k₁. k_1 = Kak₁
