It generates 36 mol of ATP per mole of glucose consumed. It generates 6 moles of CO 2 for each mole of glucose consumed It is a reductive pathway; it consumes NADH. It is present in plants, but not in D animals. It provides precursors for the synthesis of nucleotides. <E- 27/45 22 T- >

Answer 1

Answer:

Option A is Correct.

Reason: Pyruvate can then be metabolized through the mitochondrial tricarboxilic acid cycle couple to mitochondrial electron transport chain which utilises oxygen in oxidative phosphorylation. The theoretically overall yeild is 36 mol of ATP per mol of Glucose.

Option B is Correct.

Reason: It generates 6 mole of CO2 for each mole of Glucose consumed.

Option C is Correct.

Reason : It is a reductive and it consumes NADH. The pentose phosphate pathway makes the need of all organisms for a source of NADPH to use in reductive biosynthesis. The pentose phosphate pathway is primarily catabolic and serves as an alternative glucose oxidising pathway for the generation of NADPH, that is required for reductive biosynthetic reactions such as those of clolesterol biosynthesis, bile acid synthesis, steroid hormone biosynthesis and fatty acid synthesis.

Option D is Correct

Reason: The pentose phosphate pathway takes place in the cytosol  in plant cell, the same location as Glycolysis most steps takes place in plastids.

Option E is Correct

Reason : It generates NADPH and pentoses as well as ribose 5 phosphate a precursor for the synthesis of nucleotides.
