Most chemical reactions occuring in a living cell depend on the prescence of an inorganic compound known as:
1) water
2) maltose
3) glucose
4) starch
why? thanks so much for answering me in advanced

Maltose and glucose are both sugars, and all sugars are organic (mainly composed of carbon). Glucose (C6H12O6) is a 6 carbon sugar, and maltose is a disaccharide, composed of two glucose molecules joined together. Starch is a polymer (long chain) of glucose, therefore it is also organic. Water is inorganic because it does not contain any carbon (its chemical formula is H2O). Chemical reactions in a cell are aqueous, meaning that they take place in water. Therefore, the first answer is the correct one, water.

Water. The other compounds are all organic compounds--they all contain carbon. Water is the only inorganic compound in the list of choices.

1) water-water is an inorganic compound because it doesn't contain Cabon and water is needed for all cell life
