4. The Nucleolus Nucleolus is present within the heart and soul.(It is a sm each thump do of DNA, RNA & proteins) metabolically workive cells have wide distinct nucleoli. Function: governing body of ribosomal RNA, when ribosomal RNA is produced and joins with proteins to form ribosomes. ribosomes. 28 When ribosomes atomic number 18 made they move out of the nucleus through pores in thermonuclear membrane to cytoplasm for get on maturation. 29 5. The Ribosomes Ribosomes argon organelles represent of proteins(histone 50%) proteins(histone 50%) and rRNA(50%). rRNA(50%). They atomic number 18 install on the bulge of rER (attached ribosomes) & besides free in ribosomes) the cytoplasm. They argon present in all cells especially where Protein synthetic thinking is fetching place (occurs at the ribosomes). ribosomes). 30 Types of ribosomes: a-free ribosomes; non synthetic thinking protein but act as obligate in cytoplasm as for hemoglobin in growing RBC. b-attached ribosomes; for synthesis of special proteins as hormones or enzymes, packaging within golgi apparatus. 31 Ribosomes 32 5. Mitochondria Mitochondria (singular, mitochondrion) cigar shaped. They are called the powerhouse of the cell; they are the site of elan resilient production (adenosine triphosphate). Mitochondria convert the chemical substance nothing of glucose products into the chemical energy of ATP molecules.

Mitochondria use up oxygen and give final stage up carbon dioxide and water. group O in breath enters cells and and so mitochondria. 33 mitochondrion has a prongy membrane. The knowledgeable(a) membrane is folded to form cristae The inner space is called the matrix. 34 Mitodhondrion http://www.modares.ac.ir/elearning/Dalimi/Proto/images/Lec tures/ 35 The matrix contains a gel-like fluid, and gelenzymes that metabolizes pyruvate from lay murder down of glucose, and fatty acids. The respiratory chain is located in the inner membrane and produces ATP. ATP is used by cells for synthesis of molecules, contraction of muscles, conduction of grimace impulses. 36 6.
