Give an example of a limiting factor of photosynthesis
Temp, light , CO2 concentration
What will increasing light intensity do to photosynthesis?
Increasing the light intensity will increase the rate of reaction
What will increasing temp do to photosynthesis?
Increasing the temperature of the surroundings will increase
the rate of reaction,
What is the independent variable in the photosythesis practical?
The independent variable was the light intensity.
What is the dependent variable in the photosythesis practical?
The dependent variable was the amount of bubbles produced.
What is the control variable in the photosythesis practical?
The control variables were same amount of time and same amount of pondweed.
What in a greenhouse can be used to get rid of light intensity as a limiting factor?
Artificial lighting can be installed in the greenhouse to provide constant light
energy and prevent light intensity being a limiting factor.
equation of light intensity is…
light intensity is directly proportional to 1/ distance squared
What is the equation for areobic respiration?
C6H12O6 + 6O2 → 6CO2 + 6H2O
C6H12O6 + 6O2 → 6CO2 + 6H2O is the equation for what reaction?
areobic respiration?
C6H12O6 –> 2C3H6O3 + energy is the equation for what reaction?
anaerobic
what is the equation for anarobic respiration?
C6H12O6 –> 2C3H6O3 + energy
What is oxyegn debt?
The oxygen debt is the amount of
the oxygen required by the body to
convert the built-up lactic acid back
into glucose and remove it from the
respiring cells.
