而redox...
暫時先當收H+變H是oxidation吧...
所謂氧化還原同時進行...就是要有人放H+讓它吸變H才行吧..
所以氧化就是收H+,還原是放H+
你想說reduction 吧 = ="
H+, 2e-
NAD+ --------> NADH 是reduction, a net gain of H atom
只寫H+的話到 lung, digestive system buffering 時會很易亂啊
4. Krebs cycle -> aerobic respiration -> oxidation -> synthesis of NADH and FADH2 from NAD+ and FAD
不知你們的syllabus有沒有把aerobic respiration, anaerobic respiration, and fermentation 分開
但Krebs cycle 不只是aerobic respiration 才會用到的
In terms of catabolism, both aerobic respiration and anaerobic respiration require Krebs cycle. Definitions of the two respirations and fermentation are based on the final electron acceptor:
aerobic respiration - oxygen as final electron acceptor
anaerobic respiration - chemical other than organic molecules and oxygen as final electron acceptors (ex. nitrate, sulfate, metal ions)
fermentation - organic molecules as final electron acceptors (no ETC involved)
補充一下 (雖然樓主應該已知) [註: 請Physical chem 的神人別來叉我]
atom 是由 electron + proton (+ neutron) 形成
electrons 一定是 -1 charge, 所以是 electron- or e-
proton 一定是 +1 charge
neutron 是沒有charge的
hydrogen atom 是 H, 是由一粒proton 加 一粒electron 而形成的, 一正一負, 沒有任何net charge
hydrogen+ (又叫hydrogen ion) 是 少了粒electron 的 H atom, 所以只有一粒proton, 是positive charge的, 亦簡寫為H+
PA醬 (#10) 的1 及2是很適用於Bio的方便記法啊
沒有要求你背pentose phosphate, nucleic acid metabolism, glyoxylate cycle, etc 已經算仁至義盡了 , 所以請向好的方向想, 沒chem 不一定會死傷慘重的 |
