What is the major structural difference between the upper and lower epidermis in plant cells
What is the major structural difference between the upper and lower epidermis in plant cells?
The presence of low levels of cyanide arrests cellular respiration in animals, yet has little or no effect on plants. Explain how plants are able to overcome the effect of cyanide poisoning.
In a lab on enzyme kinetics the effect of enzyme concentration on enzyme activity and the effect of substrate concentration on enzyme activity were determined. If you changed the temperature,what do you think would happen to the enzyme reaction rate? Could you also explain to me what is meant by the term Q10?
If you change the concentration of enzyme in a reaction, does the Km change?
At the CO2 saturation point, is light supply the major factor limiting photosynthesis? How could you test this?
Why would the carboxylation efficiency in C4 plants be higher than the carboxylation efficiency in C3 plants?
Nitrogen fixation - electron allocation coefficient
Why does EAC have a maximum value of 0.75? What would be the likely effect on plant yield if this value declined to a very low level?
Undere natural condiitions , O2 concentration never increases to 30%. Under what circumstances would you expect nodule O2 concentration to increase under natural conditions?
Nitrogen fixation-nitrate treated plant response to increases oxygen concentration
In a lab experiment we compared the response of control(Nitrate -) and nitrate treated plants to an increase in oxygen concentrations. I concluded that nitrogenase activity increased in both plants but the increase was slightly higher in the nitrate free plant. Can you explain to me why this happened?
nitrogen fixation- nitrogenase activity
When comparing nodule specific nitrogenase activitiies in control and nitrate treated plants at 20% oxygen, why is it necessary to express nitrogenase activity per gram fresh weight of nodule tissue?
