Control of Respiration of Mitochondria from Euglena gracilis Determined by Means of Metabolic Control Analysis: Comparison of Oxidation of Matrix-and Cytosolic NADH

  • Chapter
Modern Trends in Biothermokinetics

Abstract

The mitochondria of Euglena have an outstanding capacity to oxidize cytosolic NADH as efficiently coupled to oxidative phosphorylation as matrix NADH: both paths reveal the same sensitivity to rotenone and identical P/O values1. However, they strongly differ in the rotenone sensitivity of ferricyanide reduction, indicating two separate NADH-oxidases at the inside and the outside of the inner mitochondrial membrane (see Fig. 1).
