WebCarbonic anhydrase inhibition has relatively modest consequences for global pHi regulation in contractile, spindle-shaped VSMCs in the vascular wall. 31 In con- trast, carbonic anhydrases play important roles for local pHi regulation in filopodia of migrating VSMCs. 50 As discussed in the section Acid–base equiva- lents as second messengers ... WebCarbon dioxide in solid phase is called dry ice. At the critical point there is no change of state when pressure is increased or if heat is added. The triple point of a substance is the temperature and pressure at which the three phases (gas, liquid, and solid) of that substance coexist in thermodynamic equilibrium. Back to top
