Btw 如果Final year仲追DSE都幾撚癲, 不了
我諗係pre-clin先得閒咁做，同埋唔想好似烏大龜咁

有邊d運動係屬於aerobic/anaerobic 唔係好識分。。
2018-04-05 18:37:13
想問excess tissue fluid drawn into lymph vessel 點解係by hydrostatic pressure ?
2018-04-05 18:44:03
應該做得運動就兩樣都有
2018-04-05 18:47:11
短跑係anaerobic 因為supply of oxygen is not fast enough to support aerobic respiration to meet intense energy demand.
2018-04-05 18:49:40
加翻係最前: (短跑手)sprinter required lots of energy in a short period of time.

今朝有po
通常兩種respiration皆有，但endurance sports主要靠aerobic respiration。Intense sports就主要靠anaerobic respiration。

跑100米用哂glycolysis 去generate ATP?
所以會勁多lactic acid?
2018-04-05 18:53:03
converts pyruvate to lactic acid n ATP

可以溫多陣，食飯後溫我自己入唔到腦，所以我自己都唔溫
臨訓前應該做啲relaxing啲嘅嘢
2018-04-05 18:54:46
如果食完飯煲一集劇會唔會好敗家咁
2018-04-05 18:56:20
唔會
2018-04-05 18:57:20
同問
2018-04-05 18:58:30
其實我唔係好明, 行anaerobic pathway變lactic acid 只係出2粒ATP
但係aerobic入TCA cycle 有成36粒ATP

跑100米要好短時間consume好多ATP
如果行anaerobic pathway咪好唔efficient

溫唔切禁多份pp marking pk 啦
2018-04-05 19:00:47
呢個我都真係剩係記 Not sure how to explain
2018-04-05 19:01:23
anaerobic係provide extra energy for muscle contraction
跑100m嗰陣aerobic都會同時進行 只係單靠aerobic respiration做出黎既energy係唔夠 所以要做埋anaerobic respiration
2018-04-05 19:01:55
lymph同tissue fluid contain既substance係一樣
冇concentration gradient 唔會有diffusion, 靠hydrostatic pressure入lymph vessel

點解會放到禁大
