Interfacing, also known as stabilizer, is a light piece of fabric that is sewn or fused onto fabric pieces that need an added stiffness. You would commonly use interfacing for collars, cuffs or on the facing of a shirt or jacket.
Photons of light photoexcite pigment molecules in the antenna complex. Energy from each photon is transferred to an electron, causing an excited state.hotosystem I (PSI) is an integral membrane protein complex that uses light energy to mediate electron transfer from plastocyanin to ferredoxin. The PS I system comprises more than 110 co-factors, significantly more than photosystem II. These various components have a wide range of functions.
Light-harvesting complex A light-harvesting complex is a complex of subunit proteins that may be part of a larger supercomplex of a photosystem, the functional unit in photosynthesis. It is used by plants and photosynthetic bacteria to collect more of the incoming light than would be captured by the photosynthetic reaction center alone. Light-harvesting complexes are found in a wide variety among the different photosynthetic species.
