Hey guys! Can anyone tell me if we need to know the exact numbers of the inputs and outputs of photosynthesis and cellular respiration? (e.g- 36 0r 38 atp molecules are producers in aerobic respiration or 12h20 molecules are produced etc.? btw is water produced (output) in the light independent stage?
1) With respiration, only include number's in the chemical equation:
C6H12O6 + 6O2 + 36-38 ADP + Pi -----> 6CO2 + 6H2O + 36-38 ATPIf you mean exact number of FADs and NADPs etc, then no
For photosynthesis this will suffice:
6CO2 + 6H2O ----> C6H12O6 + 6O2
Make sure you put sunlight and chlorophyll above and below the arrow to state that this process only occurs in the presence of both!
2) In the light independent stage, the only outputs are glucose, ADP + Pi and NADP. ADP + Pi and NADP are reused and re-enter the light dependent stage
do we also need to know homeostasis legit? i do not want to waste my time if it isnt even relevant (negative/positive feedback) ??
also guys how much ATP is produced in aerobic respiration? Some books say 32 others say 36-38, but apparently the examiners will mark 36-38 wrong? because it includes 37 which is impossible to be produced? not sure can someone please confirm
3) Yep. Homeostasis is very important and negative feedback helps maintain it. Defs worth learning (I'm in the process of relearning all this stuff rn!)
4) Positive feedback won't come up as much because there's few examples, someone else can confirm though
5) You shouldn't lose marks for stating 36-38 ATP or ADP +Pi, it makes logical sense.
Hope I helped
