Web78. If three coordinates of a particle change according to the equations x =3t2, y= 2t, z=4 x = 3 t 2, y = 2 t, z = 4, then the magnitude of the velocity of the particle at time t = 1 second will be. 1. 2√11 2 11 unit. 2. √34 34 unit. WebActive transport is the movement of dissolved molecules into or out of a cell through the cell membrane, from a region of lower concentration to a region of higher concentration.
WebLocated in the inner membrane of the mitochondria, ATP Synthase is involved with the electron transport chain within the same membrane. The 4 complexes of the electron transport chain create a concentration gradient of protons across the membrane; ATP Synthase is then able to utilize this concentration gradient to produce ATP. WebPolar molecules pass through lipid membranes via specific transport systems. The four types of chemical transport systems through cell membranes are diffusion, facilitated diffusion, active transport, and pinocytosis. As mentioned above, lipophilic, nonpolar chemicals dissolve in the lipid bilayer.
