Question

Biochemical reactions take place spontaneously:

• A. at pH 7 and at 298K
• B. at pH 7 and at 310K
• C. at pH 0 and at 310K
• D. at pH 10 and at 298K

Answer 1

The correct option is B at pH 7 and at 310K

Biochemical reactions take place spontaneously at pH 7 and at 310K. A biochemical reaction is the transformation of one molecule to a different molecule inside a cell, hence, the physical conditions of a body are required. These reactions are mainly controlled by enzymes. These enzymes increase the rates of biochemical reactions, so that metabolic synthesis and decompositions, impossible under ordinary conditions, may be performed at the temperatures and concentrations present within a cell.
