Question

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

Answer 1

Answer:B ATP+H2O⇒ADP+ P

Answer 2

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

Step-by-step 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.
