This can be partially explained by the following. At night CAM plants convert starch to PEP and in doing so generate NADH. This NADH is used to reduce The OAA (that is formed when PEP is carboxylated by HCO3) to malate which is stored in the vacuole. In the light, the malate is de carboxylated to release carbon dioxide, pyruvate and, importantly in relation to your question, NADPH. This NADPH can be used in the Calvin-Benson cycle to reduce 1,3-BPGA to 3-PGaldehyde. Since the NADPH has been supplied without the action of PSII, and ATP required in the Calvin-Benson cycle by photophosphorylation less water is split and less oxygen released.

Propane Chemical Structure and Formula
Because propane is made up only of carbon and hydrogen — the chemical formula is C3H8 — it's an organic compound. It's also a paraffin hydrocarbon, similar to ethane or methane.
