Question

At high temperatures, the enzymes of photosynthesis gets deactivated because

• A. They get denatured.
• B. They are proteinous in nature.
• C. They have optimum range of temperature at which they are functional.
• D. All of the above.

Answer 1

The correct option is D All of the above.

Enzymes are biological catalysts which can normally function at body temperatures. There are various different enzymes involved in the process of photosynthesis. The enzymes have optimum temperature range. This is the range in which they show maximum activity. The enzymes are proteins which gets denatured at higher temperature. The structure of these enzymes gets modified and the active sites are destroyed. This results in the inactivation of the enzymes.

Thus, the correct answer is option D.
