31. Which of the following shows the correct changes in thermodynamic properties for a chemical reaction in which Glycolysis begins the catabolic oxidation (breakdown) of glucose? (Recall that H= Enthalpy (Chemical Bonds), S=Entropy, G= Free Energy (Potential Energy) )
Read Details46. Below are some of the reactions of the Kreb’s Cycle. Carbon skeletons for amino acid synthesis are supplied by intermediates of the Kreb’s Cycle . Which intermediate of the Kreb’s Cycle shown below would supply the carbon skeleton for synthesis of a “5-carbon” amino acid? (Hint- pay attention to the 6 carbon molecule citrate that starts the Kreb cycle and where CO2 is released!)
Read DetailsBONUS! (2pts.) Aerobic Prokaryotes are able to run the Electron Transport Chain to generate ATP by Oxidative Phosphorylation. How cool! However, prokaryotes do not possess organelles like mitochondria where the Electron Transport Chain occurs. So where in these aerobic prokaryotes do you expect the reactions of the Electron Transport Chain can occur?
Read Details12. The chemical Cyanide is toxic because it binds with molecules involved in ATP production and inhibits their activity. Based on this, following exposure to cyanide where would you expect to find cyanide concentrated in a cell? (Which organelle makes ATP!)
Read Details48. Hydrogen cyanide is a nasty toxin and has been used for chemical warfare. Once inside the human body, cyanide reacts with hemoglobin and prevents oxygen from binding to hemoglobin. When this happens, oxygen levels lower, and which of the following cellular processes that uses “oxygen” will be inhibited?
