  14. Nucleoli exist from spermatocyte stage to early spermatid stage. in this process, the numbers of ribosomes, mitochondrions and endoplasmic reticulums increase until secondary spermatocyte stage, golgi apparatus emerges at the secondary spermatocyte stage, and then, these organelles change into lamellar complex which finally forms the acrosome

    核糖體，線粒體和內質網等細胞器數量逐漸增多，到次級精母細胞階段達到最大，在形成精子的過程中，上述細胞器與高爾基體及膜性泡共同分化或參與形成片層小體，並參與頂體的形成。
  15. Its surface is often covered with ribosomes, forming rough er

    內質網表面常結合有核糖體，被稱為糙面內質網。
  16. A single molecule of rta is able to depurinate 1500 - 2000 ribosomes per minute. ricin b chain ( rtb ) is a galactose - specific lectin which binds to the receptors on cell surfaces, and may enhance rta translocation by forming a pore in the membrane of intracellular organelles. ricin enters the cells by receptor - mediated endocytosis

    內吞進入細胞的蓖麻毒素一部分返回到膜表面，一部分經早期內體至晚期內體，最後在溶酶體中降解，只有一小部分約5到達高爾基體，隨后逆轉運到粗面內質網，在那裡rta才和rtb解離，游離出有催化活性的rta 。
