Question

A biochemical reaction has the following values relating to energy flow:
T = 473K
∆S = 1.11 kJ/K
∆H = -704kJ
Which of the following statements is true about this reaction?

Answer 1

The reaction is always spontaneous.
The reaction is never spontaneous.
The reaction is spontaneous only when ATP is coupled to it.
The reaction is spontaneous only when the temperature is above 0°K.

Answer 2

I think this belongs in the Chemistry section. But let me see.

Answer 3

Ok sorry but with my level of knowledge on biology, I don't really know. And you are right, it is a biology question.

Answer 4

Its ok thanks anyways. But could you help on a different one?

Answer 5

Which of the following statements is not true regarding the relationship of ATP to cellular functions?

High intracellular concentrations of ATP enable the cell to perform necessary endergonic reactions.
High intracellular concentrations of ATP may act as an allosteric inhibitor of enzymes that function in catabolic pathways.
High intracellular concentrations of ATP may be used to fuel necessary oxidation reactions.
High intracellular concentrations of ATP indicate that the energy generated from catabolic reactions exceeds the amount being used by anabolic reactions.
