Question

In glycolysis, there is one step where $NADH+H^{+}$is formed from $NA{D}^{+}$, this is when 3-phosphoglyceraldehyde (PGAL) is converted to 1, 3-bisphosphyglycerate (BPGA). This reaction shows

• A. oxidative dehydrogenation
• B. oxidative phosphorylation
• C. oxidative dehydration
• D. oxidation reduction

Answer 1

Answer: (A)

In glycolysis, we find that there is one step where $NADH+H^{+}$is formed from $NA{D}^{+}$; this is when 3phosphoglyceraldehyde (PGAL) is converted to 1, 3bisphosphoglycerate (BPGA). Two redox equivalents are removed (in the form of two hydrogen atoms) from PGAL and transferred to a molecule of NAD.
