Which chemical reaction would result in the greatest release of energy for an organism? a) adp + p --> atp b) atp + oxygen --> adp + p c) pyruvic acid + nadh --> lactic acid + nad+ d) carbon dioxide + water --> glucose + oxygen

The correct answer is B   ATP+H2O⇒ADP+ Pi

Explanation:

Among the given or mentioned equations in the question the reaction B which deals with the hydrolysis of Adenosine tri phosphate to form Adenisine di phosphate along with byproduct inorganic phosphate.

                           ATP + H2O ⇒ ADP+Pi

In this reaction 1 molecule of ATP undergoing hydrolysis or breakdown to generate 1 molecule of ADP and inorganic phosphate along with the release of -30.5 kj/mole free energy.As a result the reaction is highly exergonic and thermodynamically favorable.

  On the other hand  reaction A is an endergoic reaction that requires energy Reaction C is a fermentation reaction that does not produce energy  and finally reaction D is the reaction of photosynthesis that is totally endergonic.

that is a club

i am good at it i think hope its right

answer; i believe its echoic memory,it is believed to last three to four seconds; good luck
