anaerobic respiration

1. In alcoholic fermentation, yeast produce CO2 and ethanol as by-product; in lactic acid fermentation, no CO2 is produced. Then whether anaeroboic respiration produce CO2? In addition, if anaeroboic respiration produce CO2, where does CO2go in lactic acid fermentation?
2. In bread making, where does the ethanol produced by yeast go?
Does it vaporised during baking?

(1A)你要知道你學的aerobic respiration只得一種, 適合所有生物.
但anaerobic respiration有很多種, 在 yeast進行的, 和在muscle是完全不同的兩個完全不同的化學反應. 只是因為的特質相同, 都是把glucose分解放能量, 也不需要氧氣, 所以統稱為anaerobic respiration.
(1B) aerobic respiration和anaerobic respiration是兩個完全不同的化學反應.
aerobic respiration: A+B --> C+D
muscle的anaerobic respiration: A --> E
aerobic respiration會出co2, muscle的anaerobic respiration就是不會. 並不代表muscle會把co2吞了, 或co2與其他物質合併了. 當你讀AL時, 你就會明白的了.
(2) 你的解釋完全正確, 叻!
