Question

1. the graph below shows the effect of temperature on the rate of photosynthesis. describe what is happening during each section of the graph. photosynthesis vs. temperature experiment

Explanation:

Section L: Temperature is low, so enzyme activity (for photosynthesis) is low; the rate of photosynthesis increases gradually as temperature rises (since enzymes become more active).
Section K: Temperature continues to rise, enzyme activity increases more rapidly, leading to a steep increase in the rate of photosynthesis.
Section M: This is the peak; the rate of photosynthesis reaches its maximum (optimal temperature for enzymes).
Section N: Temperature exceeds the optimal range, enzymes denature, so the rate of photosynthesis decreases sharply.

Answer:

Section of graph	What is happening to the rate of photosynthesis?
K	Increases steeply with rising temperature
M	Reaches the maximum rate (optimal temperature)
N	Decreases sharply as temperature rises beyond optimal
