Examine the figure below, which compares the energetics of a catalyzed and uncatalyzed reaction during
the progress of the reaction from substrate (S) to product (P). The highest peak in such a diagram
corresponds to the transition state, which is an unstable, high-energy arrangement of substrate atoms
that is intermediate between substrate and product. The free energy required to surmount this barrier
to the reaction is termed the activation energy. Enzymes function by lowering the activation energy,
thereby allowing a more rapid approach to equilibrium.

referred to feedback inhibition as “Goldilocks regulation”. Describe how feedback inhibition keeps a pathway running at just the right level?
To examine: Whether the statement, "An enzyme
reaches a maximum rate at high substrate
concentration because it has a fixed number of active
sites where substrate binds", is true or false.

- The active site of an enzyme binds specifically to a substrate. Your text mentions an early idea which is that this enzyme-to-substrate interaction is like a lock and key, but it then describes a more accurate model for how enzymes bind to their substrates. Explain why the interaction is not like a lock and key and more like a hand grasping a doorknob. What is the specific name of the 'model' of how enzymes bind to their substrates?arrow_forwardCompare/contrast coordinated regulation of metabolic pathways in prokaryotes versus eukaryotes in details.arrow_forwardBoth cellular respiration and photosynthesis use APT synthase to generate APT.
