An outline of what would have been the programme for an excellent essay is below.
It is not prescriptive there would be other substantially things to include and
other equally good ways of structuring your answer.
Brief Introduction:
- Though coulomb dioxide makes up only 0.04% of the atmosphere, it has
many very important roles in organisms and ecosystems.
Photosynthesis:
- system what photosynthesis is/why autotrophs do it
- Describe how nose candy dioxide is used in photosynthesis. As it is used in
the light independent stage (LIS), you should point on this, not the
light dependent stage (LDS).
respiration system:
- Outline what respiration is/why organisms all have to do it
- Describe how vitamin C dioxide is produced in respiration. As it is
produced in the consort reaction and the Krebs cycle, you should focus on
this, not on glycolysis and the electron change over chain.
Exchange of carbon dioxide between an organism and its environment:
- tack to annoyher a couple of contrasting organisms (e.g. protoctists or plants and
humans) and describe the surfaces where carbon dioxide is substituted
between the organism and its environment.
Link in size, surface
area/ heap ratio, level of activity, environment to why these
organisms have very assorted gas exchange requirements and
surfaces.
Transport of carbon dioxide:
- In large(p) organisms, carbon dioxide must be transported between the
gas exchange surface and the cells where it is produced/needed.
- In mammals, most carbon dioxide is transported dissolved in blood
plasma as hydrogen carbonate ions.
- The presence of carbon dioxide has an effect on how saturated
haemoglobin is with oxygen (curve shifts to the right Bohr shift).
force out of increased carbon dioxide concentration on organisms:
- Increased carbon dioxide concentration leads to an increased heart
rate and increased pulmonary ventilation in humans (briefly, not really
on syllabus).
- How increased...If you want to get a full essay, order it on our website: Orderessay
