WebMitochondrial matrix. In the mitochondrion, the matrix is the space within the inner membrane. The word "matrix" stems from the fact that this space is viscous, compared to the relatively aqueous cytoplasm. The mitochondrial matrix contains the mitochondrial DNA, ribosomes, soluble enzymes, small organic molecules, nucleotide cofactors, and ... WebNov 2, 2024 · Figure 4.15: Citrate shuttle reaction moves citrate from the mitochondria to the cytosol for fatty acid synthesis. The NADPH generated through this process is necessary for fatty acid synthesis. This is one of the primary pathways that produces NADPH, and the other is the oxidative portion of the pentose pathway.
