Question

Complete the description of the pentose phosphate pathway by moving the correct term to each blank.

The pentose phosphate pathway is a two‑stage pathway that generates__________ which is a reductant in many biosynthetic reactions and takes part in detoxifying reactive oxygen species, and__________ which is a nucleotide (DNA and RNA) precursor. The substrate for the pentose phosphate pathway is__________.
The__________ phase of the pentose phosphate pathway interconverts phosphorylated monosaccharides, some of which can feed into the __________pathway.

Answer 1

Detailed in explanation.

Step-by-step explanation:

The pentose phosphate pathway is a two‑stage pathway that generates NADPH which is a reductant in many biosynthetic reactions and takes part in detoxifying reactive oxygen species, and ribose 5-phosphate which is a nucleotide (DNA and RNA) precursor. The substrate for the pentose phosphate pathway is glucose-6-phosphate.

The isomerization phase of the pentose phosphate pathway interconverts phosphorylated monosaccharides, some of which can feed into the glycolysis pathway.

Answer 2

1) NADPH .

2) Ribose 5-phosphate .

3) G6P .

4) Nonoxidative .

5) glycolytic.

Step-by-step explanation:

Hello,

In this case, each statement turn out into:

-The pentose phosphate pathway is a two‑stage pathway that generates NADPH (it is a donating electrons cofactor and a hydrogens provider to reactions catalyzed by enzymes) which is a reductant in many biosynthetic reactions and takes part in detoxifying reactive oxygen species, and ribose 5-phosphate (it is a fundamental constituent of the pyridine-based nucleotides such as nicotinamide adenine dinucleotide phosphate and nicotinamide adenine dinucleotide phosphate and the purine nucleotides adenosine diphosphate and ATP) which is a nucleotide (DNA and RNA) precursor.

-The substrate for the pentose phosphate pathway is G6P (glucose 6-phosphate, sometimes called the Robison ester, is a glucose based sugar phosphorylated at the hydroxyl group on carbon 6) .

-The nonoxidative (not carrying out oxidation) phase of the pentose phosphate pathway interconverts phosphorylated monosaccharides, some of which can feed into the glycolytic (referred to glycolysis as the metabolic pathway that converts glucose into pyruvate and a hydrogen ion) pathway.

Best regards.
