Concept explainers
(a)
Interpretation:
To explain at which step of glycolysis pathway does NAD+ participate (see Figures 28-3 and 28-4).
Concept Introduction:
Glycolysis is a glucose
(b)
Interpretation:
To explain at which step does NADH + H+ participate.
Concept Introduction:
Glycolysis is a glucose metabolizing pathway that takes place with or without the presence of oxygen. In aerobic two molecules of pyruvic acid is produced with a net gain of 1 ATP molecules. Under anaerobic conditions lactic acid is produced with no ATP.
(c)
Interpretation:
To explain as a result of the overall pathway, is there a net increase of NAD+, of NADH + H+, or of neither.
Concept Introduction:

- (15 pts) Consider the molecule B2H6. Generate a molecular orbital diagram but this time using a different approach that draws on your knowledge and ability to put concepts together. First use VSEPR or some other method to make sure you know the ground state structure of the molecule. Next, generate an MO diagram for BH2. Sketch the highest occupied and lowest unoccupied MOs of the BH2 fragment. These are called frontier orbitals. Now use these frontier orbitals as your basis set for producing LGO's for B2H6. Since the BH2 frontier orbitals become the LGOS, you will have to think about what is in the middle of the molecule and treat its basis as well. Do you arrive at the same qualitative MO diagram as is discussed in the book? Sketch the new highest occupied and lowest unoccupied MOs for the molecule (B2H6).arrow_forwardQ8: Propose an efficient synthesis of cyclopentene from cyclopentane.arrow_forwardQ7: Use compound A-D, design two different ways to synthesize E.
