| 4. | Amino transferases are located in the cytoplasm, chloroplasts and microbodies . 氨基转移酶分布在细胞质、叶绿体和微体中。 |
| 5. | The damaged chloroplasts require the addition of atp to fuel protein synthesis . 已破坏的叶绿体需要加入ATP以提供合成蛋白质的能量。 |
| 6. | The nucleus of the bleached cell was unable to direct the synthesis of new chloroplasts . 这种漂白的细胞核不能直接合成新的叶绿体。 |
| 7. | Envelope isolated from illuminated chloroplasts had much more orange zeaxanthin . 从照光的叶绿体分离出来的套膜有很多橙色的玉米质。 |
| 8. | A brief review of chloroplast structure is useful before discussing these experiments . 在讨论这些试验以前,对叶绿体结构作一简短的概述是有益的。 |
| 9. | The outer of the two membranes around a chloroplast could be regarded as the host exclusion membranes . 围着叶绿体的外面两层膜,可以看作寄主排斥的膜。 |
| 10. | The chloroplast is not a static organelle within the cell but can change shape as well as move . 在细胞中,叶绿体并不是静止不变的细胞器,而是能改变其形状和运动。 |
