AQA GCSE BIOLOGY BIOENERGETICS EXAM QUESTIONS AND ANSWERS
WITH COMPLETE SOLUTIONS VERIFIED
Terms in this set (34)
Write the word equation for photosynthesis carbon dioxide+ water -> oxygen + glucose
Write the symbol equation for 6CO2 + 6H2O -> C6H12O6 + 6O2
photosynthesis.
LIGHT INTENSITY
Name 4 factors that can affect the rate of CARBON DIOXIDE CONCENTRATION
photosynthesis. TEMPERATURE
CHLOROPHYLL
Draw a graph to show how temperature
affects the rate of photosynthesis.
Draw a graph to show how light intensity
affects the rate of photosynthesis.
Draw a graph to show how the level of
carbon dioxide affects the rate of
photosynthesis.
- increasing temperature increases rate of photosynthesis (because temperature
Describe AND explain the graph of increases the speed of chemical reactions)
temperature versus rate of photosynthesis. - increasing the temperature too much causes the rate to fall again (because
the enzymes have denatured)
Describe AND explain the graph of light the higher the light intensity the higher the rate of photosynthesis but it plateaus if
intensity versus rate of photosynthesis. the other factors are not in supply
Describe AND explain the graph of carbon the more co2 available the higher the rate of photosynthesis but it plateaus when
dioxide level versus rate of photosynthesis. other factors are limiting
Name the law that is used to link light INVERSE SQUARE LAW
intensity and distance.
Give the equation that shows the light intensity = 1 / distance squared
relationship between light intensity
and distance.
Give 5 uses of the glucose made in respiration... making cellulose... making amino acids...stored as oils or fats... stored as
photosynthesis. starch
respiration is the process of transferring energy from glucose, which goes in every
What is respiration?
cell
Why is respiration exothermic? because overall it transfers energy to the environment
The energy transferred in respiration is to build up larger molecules from smaller ones ... to allow the muscles to contract...
used for all living processes. Give 3 to keep the body temperature steady...
