The Physiology of Contractile Vacuoles [PDF]

open access: bronzeJournal of Experimental Biology, 1934
ABSTRACT On transfer from sea water to dilute sea water, the marine peritrich ciliate Vorticella marina swells more rapidly at higher temperatures. It is concluded that the permeability of the surface of V. marina to water is influenced by temperature, with a Q10 of very roughly 2·5–3·2.

Inhibition of Contractile Vacuole Function by Brefeldin A [PDF]

open access: bronzePlant and Cell Physiology, 2005
Brefeldin A (BFA) causes a block in the secretory system of eukaryotic cells. In the scaly green flagellate Scherffelia dubia, BFA also interfered with the function of the contractile vacuoles (CVs). The CV is an osmoregulatory organelle which periodically expels fluid from the cell in many freshwater protists. Fusion of the CV membrane with the plasma

THE ACTIVITY OF THE CONTRACTILE VACUOLE IN A SUCTORIAN (TOKOPHRYA INFUSIONUM)

open access: greenThe Biological Bulletin, 1951
1. Evidence is presented for the existence of a close relation between the behavior of the contractile vacuole and several phases of the functional activity of Tokophrya infusionum.2. When the process of feeding starts the pulsation rate of the contractile vacuole rises suddenly, remains high during feeding and falls gradually on cessation of the ...

PULSATION OF THE CONTRACTILE VACUOLE OF PARAMECIUM AS AFFECTED BY TEMPERATURE [PDF]

open access: bronzeJournal of General Physiology, 1925
1. The rate of pulsation of the anterior contractile vacuole of Paramecium caudatum under chloretone anesthesia has been determined over a range of temperatures from 9–31°C. It has been found that the rate is a logarithmic function of the temperature according to the Arrhenius equation. From 9–16° the temperature characteristic (µ) has the value 25,600;

THE CONTRACTILE VACUOLE IN AMOEBA PROTEUS (LEIDY)

open access: greenThe Biological Bulletin, 1938
1. The contractile vacuole in Amoeba proteus contains at the surface a well differentiated membrane about 0.5µ thick. Adjoining this membrane on the outside there is usually a layer of substance in which numerous beta granules (Metcalf's "excretory granules") are imbedded. This layer is more viscous and heavier than the adjoining cytoplasm.

A novel mechanosensitive channel controls osmoregulation, differentiation, and infectivity in Trypanosoma cruzi

open access: yeseLife, 2021
