during which process is water produced?
alcohol fermentation
acetyl coa formation
electron transport chain
citric acid cycle

electron transport chain

Explanation:

The electron transport chain includes a series of membrane-embedded proteins that accept electrons from NADH and FADH2. The final electron acceptor in the series is oxygen (O2).  

Reduction of oxygen by electrons from NADH and FADH2 results in the formation of oxidized states of reducing powers (NAD + and FAD+). During the process, oxygen is reduced into a water molecule.  

lizards have adapted to life in the desert. some desert lizards have toes with spiny scales to them run across the sand without sinking. some use the sand to hide from predators, or to search for small animals that they prey upon.
