photosynthesis+resporation問題x4

係daytime,respiration同photosynthesis係同時進行..但光合作用快過respiration'
所以net uptake係co2,net release係o2....
1.但我想問respiration唔係仲進行緊咩?佢係唔係仲放緊co2同absorb o2嫁咩?
2.compensation pt.係冇gas exchange..(光合作用rate=呼吸作用rate)
我想問係個一刻係唔係真係冇gas exchange?但佢唔係應該仲有o2 release?
3.respiration會唔會用番photosynthesis release ge o2?咁photosynthesis會唔會用番
respiration release ge co2?
4.光合作用ge dark reaction會唔會係night take place?

✔ 最佳答案
1: of crose respiration is carrying out, and it does release CO2, but all the CO2 is used in photosynthesis, and the O2 is come from photosynthesis.

2.As i said, the O2 released, is uesd in respiration.

3. yes

4. the dark reaction is take place after the light-dependent stage,
the name of dark reaction is because, the reaction do not need light , however, it can't carry oput in the dark, as the light-dependent reaction provide some material for the dark reaction
