Abstract
Fluorescence and respiratory properties of rat liver mitochondrial membranes in young and old animals have been measured. A trend toward decreasing specific activity of malate + glutamate supported state 4 respiration in mitochondria from 18 month old animals as compared to 1 month old animals is found. A concomitant decrease in membrane protein tryptophane fluorescence and an increase in a membrane fluorophore proposed to be aminoiminopropene has also been observed using nanosecond fluorescence spectroscopy techniques.
