true or false 1. Catabolism is the breakdown of substances in a biological system 2. Aromatic hydroxylation occurs primarily via 1,3 position in the aromatic ring 3. Hydrolytic biotransformation can be classified as a phase 2 metabolism reaction 4. Most drugs that distibuted in the body are in their ionized form  5. Amide drugs are not prone to hydrolysis due to the stability of the carbonyl group

Please help me identify these based on the model on the picture (even without explanation), thank you so much!1. What is metabolism? 2. What are the two types of metabolism? 3. Which metabolic reaction requires an input of energy? 4. Which metabolic reaction releases energy? 5. Which reaction yields a more complex molecule and is reductive? 6. Which reaction yields a simpler molecule and is oxidative? 7. What are the products of catabolism? Which part of the cell does this pathway take place? 8. What are the products of anabolism? Which part of the cell does this pathway take place? 9. Which reaction is divergent? Why? 10. Which reaction is convergent? Why? 11. How can you relate waterfalls to a mole of glucose? 12. What are the steps in catabolism? 13. What is the common pathway of the degraded complex molecules?

I don't get it at all. I struggled with my homework. Can you help me? Can you help me to explain to me, please?

18:34 A docs.google.com Saturated fatty acids are: Have double bonds Liquid at room temperature Solid at room temperature Hydrophilic The synthesis of polymers is made by while the breakdown of polymers is made by Dehydration; condensation Condensation; hydrolysis Hydrolysis; dehydration None of the above If you remove all of the functional groups from an organic molecule, then this molecule become Carbonyl and hydrophilic Carbohydrate and hydrophobic Carboxyl and hydrophobic Hydrocarbon and hydrophobic

H8. Glucose labeled with 14 C at C-1 is added to a solution containing the enzymes and cofactors of the oxidative phase of the pentose phosphate pathway (aka hexose monophosphate pathway) which compounds will contain radioactive carbon? - Ribulose 5 phosphate, no label will be found, all compounds will be labeled, erythrose 4- phosphate, 7-[hps[hpsedoheptulose, fructose 6- phosphate, grlyceraldehyde 3-phosphate, xylulose 5 phosphate ribose 5 phosphate

Regarding the mechanism of action of chymotrypsin, the formation of a strong hydrogen bond with the hydroxyl group (serine amino acid) increase its: Basicity Nucleophilicity All the answers are correct Electron density

4. Consider the structure shown below. Give one cycle of the reactions of the - oxidation of fatty acids. Show all the structures of the compounds involved; indicate whether the reactions are reversible or not; show the use or generation of co-factors wherever it occurs.

Help me please

guanosine and a water bind in the active site, does not matter in which order. The scissile N-1 glycosidic bond between the anomeric carbon and N9 of the base is broken resulting in an oxocarbenium transition state. The leaving group electrons are not protonated, but instead swing up to form a double bond between N9 and C8. The double bond that is already present on the purine swings out on N7 and is protonated by an active site histidine acting as a general acid. An active site aspartate acts as a general base, and deprotonates the water substrate molecule. The deprotonated water is then free to attack the transition state in a manner that will generate an αribose. Draw the active site and show how the mechanism works. You will need to draw 3 or 4 different active site “snap-shots” to show the entire process. Be sure to clearly show the transition state and how it might be stabilized
