C)|Myth: The specificity of an enzyme for its substrate is explained by the lock and key hypothesis. Fact: The
lock and key hypothesis is outdated! What is our current model for understanding regarding how enzymes
recognize and bind to substrates?

- Test Your Understanding 8. Induced fit means that when a substrate binds to an enzymes active site, (a) it fits perfectly, like a key in a lock (b) the substrate and enzyme undergo conformational changes (c) a site other than the active site undergoes a conformational change (d) the substrate and the enzyme become irreversibly bound to each other (e) c and darrow_forwardBiochemistry: Diagram the biosynthetic pathway from precursors (like amino acids, PRPP, etc.) to dTTP.

- Inquiry and Analysis Do Enzymes Physically Attach to Their Substrates? When scientists first began to examine the chemical activities of organisms, no one knew that biochemical reactions were catalyzed by enzymes. The first enzyme was discovered in 1833 by French chemist Anselme Payen. He was studying how beer is made from barley: First, barley is pressed and gently heated so its starches break down into simple two-sugar units; then yeasts convert these units into ethanol. Payen found that the initial breakdown requires a chemical factor that is not alive and that does not seem to be used up during the process-a catalyst. He called this first enzyme diastase (we call it amylase today). Did this catalyst operate at a distance, increasing the reaction rate all around it, much as raising the temperature of nearby molecules might do? Or did it use physical contact, actually attaching to the molecules whose reaction it catalyzed (its "substrate")? The answer was discovered in 1903 by French…arrow_forwardSelect all that apply.

The energy of activation is lowered so the reaction can happen quicker. 2. Substrate attaches to the active site. 3. The product is created and released from the active site. 4. The energy of activation is lowered so the reaction can happen slower. 5. A specific substrate attaches to the active site.
