A Circadian Rhythm in Oxygen Uptake by Samanea Pulvini
AUTOR(ES)
Satter, Ruth L.
RESUMO
The rate of O2 uptake by excised Samanea pulvini oscillates with a circadian rhythm during 52 hours of darkness. Rates of respiration increase during pulvinar opening and decrease prior to and during closure, consistent with the concept that opening requires a greater expenditure of energy. Externally supplied sucrose, necessary for perpetuation of the leaflet movement rhythm, has a small promotive effect on the rate of respiration.
