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.
Chloroplast. Photosynthesis occurs in eukaryotic cell structures called chloroplasts. A chloroplast is a type of plant cell organelle known as a plastid. Plastids assist in storing and harvesting needed substances for energy production.A chloroplast contains a green pigment called chlorophyll, which absorbs light energy for photosynthesis.he light reaction stage takes place in the presence of light and occurs within the chloroplast grana. The primary pigment used to convert light energy into chemical energy is chlorophyll a. Other pigments involved in light absorption include chlorophyll b, xanthophyll, and carotene.
