4. (3 points) Complete the following reactions by showing all of the reactants necessary for the transformations. Clearly identify stereochemistry where appropriate. Balance the reactions. ketone + (CH3)3P=0 ketone ketone
1) In general, how does the reaction rate depend on the concentrations of the reactants? 2) Why does the reaction rate chane as you alter the experimental consitions by changing the initial concentrations? 3) What effect does a catalyst have on the rate constant?
1. What is the overall goal of cellular respiration? What are the reactants of cellular respiration? What are the products of cellular respiration? 2. Why is cellular respiration also called aerobic respiration? 3. Is glucose oxidized or reduced? Is oxygen oxidized or reduced? 4. Why is it important that there are many small intermediate steps in cellular respiration rather than one or two short bursts of metabolic energy? 5. What critical role does NAD+ and FAD play in cellular respiration?...
What are the products AND reactants of sulfoxide formation phase 1 reactions?
4) (2 pts each) Outline a synthesis (i.e., simply show the reagents/reactants for the necessary reactions) for each compound below from the designated starting material. Use reagents you've learned about in Orgo I and II. The number of arrows does not necessarily correspond to the number of steps required. As a general rule, any carbon units in the products that were not in the starting materials should come from molecules containing 7 or fewer carbons. Things that don't end up...
the reactants are different
some solutions do not explain this !
5. Consider the following two reactions for the synthesis of ethanol: C2H4 (g) + H20 (g) = C3H2CH2OH (1) C2H6 (g) + H20 (g) C3H2CH2OH (1) + H2 (g) Which would be the more thermodynamically feasible at standard condition? Why?
1. What are the different sources of energy available to living organisms? 2. How do the acquisition and the use of energy by living organisms work according to the laws of thermodynamics? 3. Explain the energy use in the following reactions: endergonic/exergonic. 4. What is metabolism? How are chemical reactions related to metabolism? Why is energy needed to run a metabolism? What are coupled reactions? 5. Draw a picture of ATP. Why is this molecule so important for cells? How...
3. For the following reactions, label the reactants as electrophiles (E) or nucleophiles (N). (2 marks) og modo NaOH v Br - V on NaBr
Photosystems
Photosystems: 1. Circle the letter of each sentence that is true about the light-dependent reactions. Correct the false statements. a. They convert ADP into ATP. b. They produce oxygen gas. C. They convert oxygen into carbon dioxide. d. They convert NADP* into NADPH. 2. Where do the light-dependent reactions take place? 3. What happens to water in the light-dependent reactions?
2.(20) The following five reactions show reactants, reagents and products. In each reaction one of the categories is missing (represented by a letter). Supply the missing reactant, reagents or product where appropriate in each reaction. In your structures, be sure to indicate stereochemistry where warranted. A= a) b) H2, 5%Pt/C CH212. Zn(Cu) in ether c) C : CH Br2 in H20 d) D : phase transf. cat OH 1) Hg(OAc)2, H20 2) NaBH4 e)
