Question set 3 1. respiration is regulated by feedback inhibition, the end product of an anabolic pathway inhibits the enzyme that catalyzes the early step of the pathway. 2. allosteric enzyme: an enzyme whose function at one site is determined by the regulatory molecule that is bound to another site, creating either inhibition or stimulation. It works in the above process because at stimulators are produced at the start of the pathway, and inhibitors are produced at the end, so enzymes catalyze reactions when they need to, and are inhibited when they are no longer needed. 3. because proteins are structural molecules, and if we start to digest proteins we will eventually break down the cells that make up our tissues. This would occur when there is no more sugar to break down. 4. Rotenone inhibits the transfer of electrons, cyanide inhibits enzymes from binding to

Unformatted text preview: oxygen, and carbon monoxide inhibits the binding of oxygen to hemoglobin, all of which stop the production of ATP. However DNP kills by using energy rapidly, without replacing the ATP used. 5. fermentation runs along with glycolysis, it transfers electrons from NADH to pyruvate, the remaining NAD+ oxidizes sugar by glycolysis to generate ATP. 6. the fact that glycolysis doesn’t use oxygen, and oxygen wasn’t present in the atmosphere until 2.7 billion years ago seems to show that glycolysis has been around for a long time. 7. if you flood a cell with the enzymes and activators that metabolize glucose in a patient with a reduced glucose metabolism, the addition of the enzymes will metabolize the glucose as if they were naturally there, like in someone with a normal glucose metabolism....
