Based on the graph, how would you say CO2 concentration affects the rate (speed) of photosynthesis in plants?
In general, plants have a maximum (a) of the photosynthesis reaction. There is always a peak regardless of if you keep adding CO2, water, or light.
Why are bubbles a good indication of the rate of photosynthes? What specifically are these bubbles?
Choose the following conclusions about the experiment/data that are valid. (Multiple select)
As you raise the CO2 concentration, the rate of photosynthesis decreases.
Without any CO2, photosynthesis cannot occur.
As you raise the CO2 concentration, the rate of photosynthesis increases.
Rate of photosynthesis will always increase as give the plant more CO2.
The rate of photosynthesis doesn't increase from 4.0 to 5.0% CO2. A max speed is reached.
How would you desribe the effects of changing light intensity on photosynthesis based on this data? (Use numbers to prove your point)
What happens to the rate of photosynthesis as you increase from 100 W/m2 light intensity to 125 W/m2 light intensity? What does this tell you about lights effect on photosynthesis?
There is an enzyme called Rubisco that helps convert CO2 into glucose during the light independent (calvin cycle) reaction. How does this data help back up the ideas of enzymes denaturing?
At 30 degrees, the Rubisco enzyme is fully denatured and oxygen production peaks.
Only high temperatures denatur the Rubisco enzyme, as oxygen production goes down above 30 degrees.
Temperatures above and below 30 degrees starts to denature rubisco, lowing Oxygen production/PS rate.
Rubisco is not able to be denatured, it is resistant to any big changes in temperature.
