Above 380C and below OoC the rate of photosynthesis decreases. Propose a hypothesis to explain why this occurs.
Effectus [21]

<u>Answer:</u>

<em>Enzyme activity decrease at these temperatures. </em>

<u>Explanation:</u>

Photosynthesis is facilitated by the action of various enzymes and involves light and dark reactions.  In <em>light reactions chlorophyll absorbs sunlight and creates ATP AND NADPH</em>. In dark reactions carbon is fixed using the <em>ATP and NADPH. </em>

The efficiency of all these activities depends on the activity of enzymes which depends on the temperature. The optimum temperature range where the enzyme activity is optimal is about <em>10°c - 20°c</em>. At low temperatures and high temperatures enzyme activity is less efficient.

<em>At a temperature above 38°c and below  0°c enzyme activity decreases. </em>
