標題: [嘖嘖] 生化課上抄的，不知道是不是作業
1. The formation of a peptide bond( which links two amino acids together) is an
endergonic reaction. How can such endergonic reaction take place in a living
cell smoothly?
2. Give the four elements that make up 99% by weight of living matter.
3. Write down the srable electronic configurations of these elements.(上題延伸)
4. Why DNA is more stable than RNA? (Explain it in chemical conception)
另補個重點，老師說要我們記清楚ATP的化學結構喔!! 而且要記得那兩個鍵比較容易斷
