In these chloroplasts carbon dioxide combines with phosphoenolpyruvate to form oxaloacetic acid, which is transported to the bundle sheath cells, where the carbon dioxide is released, then fixed by the enzyme ribulose bisphosphate carboxylase to form glycerate 3 - phosphate, the first step in the calvin cycle
在葉肉細胞的葉綠體中二氧化
碳與磷酸烯醇丙酮酸結合形成草酰乙酸,后被運到鄰近的維管束鞘細胞,在那裡二氧化
碳被釋放,后被
核酮糖二磷酸羧化酶固定形成3磷酸甘油酸,這是卡爾文的循環第一步。
On the other hand, if the mass of the star is greater than about 1. 1 solar masses, the dominate reaction will be the carbon - nitrogen - oxygen cycle
假若星體質量更大,
核聚變便會主要以
碳氮氧循環cno循環
The net effect of the cno cycle is the same as the p - p chain. but carbon is used as a catalyst
的方式進行,這循環所造成的結果和質子質子鏈沒有分別,都是把四顆氫原子
核結合為一顆氦原子
核碳的作用猶如催化劑。
The cno cycle is faster and more energy is produced per second. in order to effectively transport the heat energy out from the star, its core has to be convective
碳氮氧循環的反應比較快,可以產生更多能量而只有對流
核心能將這些多的能量有效地傳遞出去。
Since a carbon nucleus is six times more positively charged than a hydrogen nucleus, the cno cycle can only operate at the higher temperature and density provided by the more massive stars
但因
碳原子
核帶的電荷是氫原子
核的六倍
碳氮氧循環需要只有質量大星體所能提供的較高溫度和壓力才能維持。
