WebDiffusion is the movement of particles from a high to lower concentration. Osmosis is the diffusion of water across a membrane. Active transport moves particles from low to higher concentration. WebThe potential energy of an electrogenic pump is coupled to ATP synthesis in mitochondria. 3. “Simple” Active Transport: The passage of some substances through membranes against a concentration gradient is unidirectional but not coupled to ionic movement even though ATP is consumed in the process.
