How Is Glycolysis Pentose Phosphate Pathway And Tca Cycle Linked?

How Is Glycolysis Pentose Phosphate Pathway And Tca Cycle Linked? The glycolysis and pentose phosphate pathways (PPP) are tightly connected. The glucose entering the in cell membrane is rapidly phosphorylated by HK and converted to G-6-P. The G-6-P is metabolized either by the glycolytic pathway, generating pyruvate and lactate, or by PPP to produce NADPH.
