Discuss the composition of the transition state for the formation of ATP by ATP Synthase.
a) Where is the active site for this enzyme located?
b) How are the amino acid side chains from the α and β subunits of ATP Synthase involved?
c) Discuss the importance of Mg+2 in the mechanism of this enzyme.
Describe the conformational changes (including substrates that bind to the different conformations) that occur in the F1 domain of ATP Synthase that result from protons flowing through the Fo domain down their concentration gradient:
Please explain why hydrolysis of ATP can release much energy by describing how the products of ATP hydrolysis are more stable. Please describe how ATP hydrolysis is used for glucose absorption (i.e. picking up glucose from the small intestine into epithelial cells)
