View full solution → Name the products of oxygenation of RuBP.
Expand RuBisCO.
Mention the possible location in the chloroplast, where cyclic flow of electrons (cyclic photophosphorylation) occurs.
What is the basis for designating $\mathrm{C}_3$ and $\mathrm{C}_4$ pathways of photosynthesis?
View full solution →ATPase enzyme consists of two parts. What are those parts? How are they arranged in the thylakoid membrane? Conformational change occurs in which part of the enzyme?
Name the end products of light reaction of photosynthesis. Mention the fate of each of them.
Name the end products of light reaction of photosynthesis. Mention the fate of each of them.
How does water stress affect/ decrease the rate of photosynthesis?
Which products formed during the light reactidn of photosynthesis are used to drive the dark reaction?
Mention the four basic requirements for chemiosmosis to occur.
Suppose there were plants that had a high concentration of Chlorophyll b, but lacked chlorophyll a, would it carry out photosynthesis? Then why do plants have chlorophyll b and other accessory pigments?
Look at leaves of the same plant on the shady side and compare it with the leaves on the sunny side. Or, compare the potted plants kept in the sunlight with those in the shade. Which of them has leaves that are darker green ? Why?
By looking at a plant externally can you tell whether a plant is $\mathrm{C}_3$ or $\mathrm{C}_4$ ? Why and how?
View full solution →By looking at which internal structure of a plant can you tell whether a plant is $\mathrm{C}_3$ or $\mathrm{C}_4$ ? Explain.
View full solution →RuBisCO is an enzyme that acts both as a carboxylase and oxygenase. Why do you think RuBisCO carries out more carboxylation in $\mathrm{C}_4$ plants?
View full solution → Why is the colour of a leaf kept in the dark frequently yellow, or pale green? Which pigment do you think is more stable?
Even though a very few cells in a $\mathrm{C}_4$ plant carry out the biosynthetic – Calvin pathway, yet they are highly productive. Can you discuss why?
View full solution →Give comparison between the following: Cyclic and non-cyclic photophosphorylation
Give comparison between the following: $C_3$ and $C_4$ pathways
View full solution →Figure shows the effect of light on the rate of photosynthesis. Based on the graph, answer the following questions:
-
At which point/s (A, B or C) in the curve is light a limiting factor?
-
What could be the limiting factor/s in region A?
-
What do C and D represent on the curve?
