The processes that occur in the electron transport chain are also known as oxidative phosphorylation. Suggest why this term is used
State one advantage of mitochondrial membrane being highly folded to form cristae to the electron transport chain
The oxygen taken up by organisms has an important role in aerobic respiration. Explain this role.
As part of which molecule does the oxygen taken in leave an organism after being respired
State 3 reasons for the small % of energy transferred at each trophic level
Why most food chains rarely have more than 4 trophic levels
Two advantages of using a pyramid of biomass rather than a pyramid of numbers when representing quantitative information on a food chain
How pyramid of biomass for marine ecosystem may sometimes show producers (phytoplankton) with a smaller biomass than primary consumers(zooplankton)
Units to measure biomass
Net productivity (def)
Why productivity of an agricultural ecosystem is greater than that of a natural ecosystem
What are the differences between the ways that energy is provided in a natural ecosystem and in an agricultural ecosystem
How does rearing animals intensively in small covered enclosure increase their energy conversion rate
Why keeping animals in the dark for longer periods might improve the energy-conversion rate
How many carbon molecules are there in a single molecule of pyruvate
What 2C molecule is pyruvate converted to during link reaction
In which part of the cell Krebs cycle takes place
What are the biochemical outcomes of the LD reactions
Limits on the rate of photosynthesis
How much ATP is produced during aerobic respiration
How NAD is regenerated when muscle cell respire anaerobically
How is NAD regenerated when yeast cells respire anaerobically
What is oxygen debt
The role of acetyl CoA in aerobic respiration
Why are there a limited number of trophic levels in an ecological pyramid and links in a food chain
Why is pyramid of energy the best way of representing feeding relationships between organisms in different trophic levels.
Eutrophication
Eutrophication causes:
Evolution is sometimes defined as a result of changes in the frequency of particular alleles. Explain the definition in terms of natural selection
Summarise the different stages of photosynthesis
How structure of chloroplast maximises a rate of reaction
Carotenoids
Difference between non-cyclic/ cyclic photophosphorylation
