On electrical switch it has cu wire only what does that mean. Devices marked CU-only are intended for use only with copper wire (wire systems with solid-core copper wiring) and should not be used with aluminium electrical wiring.heck out some tips on how to choose switches and outlets while avoiding pitfalls at Kyleswitchplates.com.

Best Answer: ATP and NADPH are both produced by the mitochondria. SImple sugars (carbon chains) are dismantled and broken down to create ATP and NADPH. Glycolsis (simple sugars) are used to create the NAD molecules and the ATP. Produces Nadph.
The ATP and NADPH used in these steps are both products of the light-dependent reactions (the first stage of photosynthesis). That is, the chemical energy of ATP and the reducing power of NADPH, both of which are generated using light energy, keep the Calvin cycle running.
