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.

The following absorbance data were obtained for a 0.00035 M solution of HX in 0.1 M NaOH and 0.1 M HCI. Measurements were made at wavelengths of 450 nm and 620 nm using a 1.0 cm glass cuvette. 450 620 A(460 nm) A(630 nm) 0.1 M NaOH 0.1 M HCI 0.065 0.435 0.895 0.150 In the 0.1M NaOH solution, the indicator will be almost 100% in the X- form, while in 0.1M HCI, the indicator will be nearly 100% protonated (HX). Calculate the acid dissociation constant for the indicator if a pH=5 buffer solution containing a very small amount of indicator exhibits an absorbance of 0.567 at 450 nm and 0.395 at 620 nm (measured in a 1 cm glass cuvette).arrow_forwardShow work...give the name of the given compound.
