Diffusion; Active transport; Further explanation: Via diffusion, small water molecules can move across the phospholipid bilayer acts as a semi-permeable membrane into the extracellular fluid or the cytoplasm which are both hydrophilic and contain large concentrations of polar water molecules or other water-soluble compounds. Active transport requires the input of energy, whereas passive transport is primarily driven by the gradient.Active transport requires energy, whereas passive transport does not. D Watch this clip from the The rate constant for this second-order reaction is 50.4 L/mol/h. Thus, in a single cell, there can be different rates and directions of diffusion for different molecules. 1.Because all cells have a plasma membrane, it is logical to infer that membranes first developed in the earliest forms of life on Earth the hydrophobic interior of the membrane. Active transport requires an input of energy and moves molecules against their concentration gradient. "active movement of particles INTO a cell". Deltoid muscle _____ 2. Part A Although the motion of each individual molecule is random, there can be directional motion of an entire population of molecules. hydrophobic interior of the lipid bilayer are nonpolar. b) exergonic; The energy released by an exergonic reaction can be used to drive an endergonic reaction. The shape change only occurs due to the binding of the carrier protein's target molecule, in accordance with a concentration gradient.
