The myelin sheath that covers many cns axons is formed by oligodendrocytes.
Oligodendrocytes are type of neuroglia (non-neural cells found in central nervous system) with protective, trophic and supportive role. Their function is to insulate axons (with myelin sheath), in the central nervous system (CNS) which is, equivalent to the function performed by Schwann cells in the peripheral nervous system (PNS).
The light reactions of photosynthesis supply the Calvin cycle with (d) ATP and NADPH.
Light reactions are photochemical reactions which are directly driven by light. They are responsible for the synthesis of ATP as well as NADPH.
Light reactions take place in the membranous system that is present within the chloroplasts. The membrane system consists of grana, the stromal lamellae and the matrix stroma.
The products of light reaction include ATP, NADPH as well as O₂. However, ATP as well as NADPH are used in driving the processes which result in the production of sugars, whereas O₂ diffuses out of the chloroplast.
