<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>
Uranium is not a fossil fuel.
