How does low light intensity affect photosynthesis?
it limits the light-dependent stage
it slows the light-independent stage
it reduces the production of ATP and reduced NADP
all of the above
|
What happens to the rate of photosynthesis at very high light intensity?
it stops
it decreases
it increases
it plateaus
|
What is the light compensation point?
when the volume of oxygen produced equals the volume of carbon dioxide absorbed
when the volume of carbon dioxide produced equals the volume of oxygen absorbed
when the volume of oxygen absorbed and carbon dioxide produced in photosynthesis is balanced by the oxygen produced and the carbon dioxide absorbed by respiration
when the volume of oxygen produced and carbon dioxide absorbed in photosynthesis is balanced by the oxygen absorbed and the carbon dioxide produced by respiration
|
Which is NOT an effect of low carbon dioxide concentration on photosynthesis?
it reduces the production of GP and TP
it limits the light-dependent stage
it decreases the rate of photosynthesis
it limits the light-independent stage
|
What happens to the rate of photosynthesis at high carbon dioxide concentration?
it increases
another factor like light becomes limiting
it decreases
it stops
|
What is the saturation point in photosynthesis?
when the factor being measured is no longer limiting the reaction
when something else becomes the limiting factor
both of the above
none of the above
|
What happens to the rate of photosynthesis at very high temperatures?
it decreases sharply
it stops
it plateaus
it increases
|
What happens at an intermediate light intensity compared to a low light intensity in photosynthesis?
(Select all that apply)
more TP gets converted to GP
RuBP is regenerated more quickly in the light-dependent stage
RuBP is regenerated more quickly in the light-independent stage
more GP gets converted to TP
more ATP and reduced NADP are produced in the light-dependent stage
|
What happens at an intermediate temperature (below the optimum) compared to a low temperature in photosynthesis?
(Select all that apply)
increased rate of photosynthesis
increased kinetic energy supplied to enzyme-catalysed reactions
decreased rate of photosynthesis
enzymes denature
|
What is the term for a factor that is in shortest supply in photosynthesis?
|
