Role of H+ and Ca++ concentrations on Vorticella stalk Contraction Determination
Keywords:
H+, Ca++ concentrations, Vorticella stalk, contraction determinationAbstract
Vorticella stalks contraction mechanism is based upon the behaviour of novel types of motor proteins involved in the process and thus determined positive sensitive effects when in [H+] from 14.80 × 10-10 to 7.15 × 10-10 mole whereas [Ca++] from 0.5 to 4.5 mM reflected negative effects on contraction dynamics in terms of birefringence. The protoosmotic applications on the stalk contraction provided information about biochemical nature of motor proteins involved in contraction dynamics of the stalk in terms of frequency and duration profiles in reversible reactions have potential future applications in controlling patterns of structural modifications of motor proteins involved throughout the system.
