係absorption
同root都幾似
對呀 bio真心難中marking
樓上巴打應該係冇錯 但係answer就係話
Provide more nutrient and oxygen
Cells can carry out more aerobic respiration
Release more energy for nutrient absorption by active transport

如果係講respiration >>A.T 。應該係講blood supply increase>supply of o2 increase / rate of removal of co2 increase>>>respiration rate increase?
寫哂嗰logical flow就實冇錯、冇欠漏
其實faster removal of co2 可唔可以speed up rate of respiration?
兩樣嘢冇關係
巴打我都係同你一樣咁答
考果時諗住2個寫哂大包圍就算
明明識又中唔到marking感覺好唔抵

因為我之前見過有條實驗題講seed germination ,話如果有co2 accumulate 既話會inhibit seed respiration rate。可唔可以證到co2 會影響respiration?
會唔會係因為accumulation of CO2導致conc. of O2 reduces
呢樣嘢你本身唔洗識，佢只係比咗額外資料你考你思維。
加ADP入Krebs cycle 點解可以令佢更加快
太多資料反而擾亂自己
大家
咁呢個答法啱唔啱

plant respiration 學校完全無教過 
，有無巴打可以講下佢地之間嘅compare and contrast
，有無巴打可以講下佢地之間嘅compare and contrastCO2 conc higher than normal range-> dissolve in water-> lower ph-> enzyme can only work in a limited range of ph-> decreased enzymatic activity of ATPase-> inhibit seed respiration rate?
吹出嚟
吹出嚟咩叫更快先
我記得Krebs cycle 係將6-c轉做4c同時拎能量

但係腸都會有alkaline 液體分泌
咁講應該唔會影響到

coenzyme A係咪respiration唯一enzyme?
more oxygen is transported to gut for respiration in mitochondria to release more energy, which promote active transport of nutrients
rapid diffusion rate help transport absorbed food substance more quickly to maintain steep conc. gradient

佢好似都唔係enzyme
ADP唔係store energy in a readily unstable form咩
唔係好明想問咩

Enzyme唔等於coenzyme
只需知道respiration involves many enzymes, no need details。
