Rodrigo is an enzyme engineer. He wants to know which of four peptide substrates is bound most tightly by his engineered enzyme. Which value should he measure and pay attention to? Km KCAT Vo Both A and B kcat, [S], and [E]t Rodrigo's enzyme was assayed with three substrates (A, B, and C). The SAME enzyme concentration used was for each of the three reactions.

A change in the process requires a higher temperature. The temperature of the pipe increases from T-800 K to T2 900 K. Now, the flux will change because diffusion will be easier at higher temperatures. This will cause the value of D in Fick's First Law to increase. Assume that the activation energy for the diffusion of hydrogen through the pipe is Ed 1.51x104 J/mol. What is the leak rate for the new process? Express your answer to three significant...
