Question

Which is correct for biochemical reactions?

• A. These are specific in nature.
• B. They occur spontaneously.
• C. Take place at body temp.$\left(310K/{37}^{\circ }C\right)$ and 1 atm.
• D. All of these.

Answer 1

Answer: (D)

All of these.

Biochemical reactions are specific in nature and occurs spontaneously. They takes place at body temp. $\left(310K/{37}^{\circ }C\right)$ and 1 atm. A biochemical reaction is the transformation of one molecule to a different molecule inside a cell (hence, body temperature). Biochemical reactions are mediated by enzymes, which are biological catalysts that can alter the rate and specificity of chemical reactions inside cells. These proteins can specifically catalyze a single reaction, so that reactions can be controlled very precisely. The reaction takes place in the active site, a small part of the enzyme which is usually found in a cleft or pocket lined by amino acids residues, and the rest of the enzyme is used mainly for stabilization.
