These URMs are: (i) positive cooperative binding, (ii) homo-multimerization, (iii) multistep signalling, (iv) molecular titration, (v) zero-order covalent modification cycle and (vi) positive feedback. WebThe kinetic energy (KE) of a particle of mass ( m) and speed ( u) is given by: KE = 1 2mu2 KE = 1 2 m u 2. Expressing mass in kilograms and speed in meters per second will yield energy values in units of joules (J = kg m 2 s –2 ). To deal with a large number of gas molecules, we use averages for both speed and kinetic energy. flow sharepoint filter query
