Question

Most of the biochemical reactions differ from those occurring in the non-living world in

• A. Being spontaneous
• B. Releasing energy
• C. Being enzymatic
• D. Requiring energy

Answer 1

The correct option is C

Being enzymatic

The correct option is option C.

Explanation of the correct option:

1. Biochemical reactions are those chemical reactions that take place inside a cell.
2. These reactions are different from reactions occurring outside the cell or in a non-living system.
3. These are all catalyzed by enzymes.
4. Enzymes are called biocatalysts because they can increase the rate of reaction by lowering their activation energy.
5. Enzymes are found only in biological or living systems.

Explanation of the incorrect options:

Option A: Both biochemical reactions and reactions that occur in a non-living system can be spontaneous.

Option B: Both biochemical reactions and reactions that occur in non-living systems can be energy-releasing.

Option D: Both biochemical reactions and reactions that occur in a non-living system can be energy-consuming.

Final answer: So, most of the biochemical reactions differ from those occurring in the non-living world in being enzymatic.
