Which carbohydrate metabolic pathway is characterized by the conversion of glucose-6-phosphate into ribose-5-phosphate?

A Glycolysis
B Gluconeogenesis
C Pentose Phosphate Pathway ✓
D Citric Acid Cycle

Explanation

The Pentose Phosphate Pathway is a metabolic pathway that generates ribose-5-phosphate and NADPH from glucose-6-phosphate, playing a crucial role in nucleotide synthesis and antioxidant defense.

Mnemonic

'Pent' = 5-carbon sugars, 'Phos' = phosphate group transfer
