OSMOTIC PRESSURE AND ELECTRICAL ACTIVITY

The effect of osmotic pressure on succinoxidase activity.

Structural damage to mitochondria is known to cause diverse effects on the activities of enzymes linked to those particles (2). Some systems are activated or have their activity enhanced by many procedures damaging to the mitochondria, while others suffer considerable loss in activity (2). Hypotonic solutions are frequently employed to disrupt structural integrity, and, when increases in activi...

Brownian motion, hydrodynamics, and the osmotic pressure

It is shown that the osmotic pressure of a colloidal dispersion can be interpreted as the isotropic part of the macroscopic particle stress in the suspension. The particle stress is in turn expressible in terms of hydrodynamic interactions among the suspended particles. Thus, there is a completely mechanical definition of the osmotic pressure, just as there is for the pressure in a molecular fl...

CALCULATION OF OSMOTIC PRESSURE USING A CLOSED SYSTEM MODEL

In this work we have used a closed system model to derive an analytical equation for the osmotic pressure of two component electrolyte and non-electrolyte solutions. In order to do so, we have used an equation of state, known as the dense system equation of state (DSEOS), for the model system. Based on the model, a new definition is given for the osmotic pressure of a closed system. Good ag...

Maintenance of Osmotic Pressure within the Nucleus

Lipid tubule growth by osmotic pressure.

We present here a procedure for growing lipid tubules in vitro. This method allows us to grow tubules of consistent shape and structure, and thus can be a useful tool for nano-engineering applications. There are three stages during the tubule growth process: initiation, elongation and termination. Balancing the forces that act on the tubule head shows that the growth of tubules during the elong...
