42+ Biology Active Transport Example Background. Photosynthesis is an example of active transport using light energy. In cellular biology, active transport is the movement of molecules across a cell membrane from a region of lower concentration to a region of higher concentration—against the concentration gradient.
A Level Biology Active Transport Revision - YouTube from i.ytimg.com Other sections include plants, animal systems, vertebrates, and microorganisms. The proteins involved in this case use the energy of photons to create a proton gradient in plants, abc transporters are frequently found inside cell and organelle layers, for example, the mitochondria, chloroplast, and plasma film. The particles move against the concentration gradient, using energy released during respiration.
