vincent561: What re islets? It is not just ''ISLETS''....it is exhaustively referred to as ISLET OF LANGHERHANS. There are 3 main cells comprising the ISLET OF LANGHERHANS,they 1)ALPHA-CELL(responsible for GLUCAGON) 2)BETA-CELL(responsible for INSULIN) 3)DELTA-CELL(responsible for the production of SOMATOTROPHINE HORMONE for growth of the body) 1 Like |

ISLET: a small group of cells that is structurally distinct 4rm d surronding cells. |
| Re: Biology, Chemistry and Physics tutorial thread for jamb by Nobody: 8:03am On Jan 07, 2014 |
Dr. Laz'Devitan:nope ....."islets" is a term .....islet of langherhans is an example of "islets" ......he was asking what an islet is ....so ur answer, though educative, is off context Dr. Laz'Devitan: |

vincent561: ISLET: a small group of cells that is structurally distinct 4rm d surronding cells. Oh!...yes....that's with ANATOMY......most time when i see most of your questions......i got many things to say...and several issues immediately comes into my reins!... |

(1).The largest organ in man is ? (2),During digestion in man,what converts insoluble caseinogen to soluble casein? (3).The total number of teeth in Man,Rabbit and Dog respectively are? (4).The oily liquid secreted by the sebacious gland is? (5).What holds the testis to the scrotum? |
| Re: Biology, Chemistry and Physics tutorial thread for jamb by DrLazDevitan: 4:56pm On Jan 07, 2014 |
Prince adebayo: (1).The largest organ in man is ? Answers 1. LIVER(mostly visceral organs of the ABDOMINAL CAVITY) 2)Pepsin makes soluble the curds of CASEIN! 3)Man=32.....Dog=42.....Rabbit=28 4)Sebum 5)what is supporting the testis in the scrotal sac are mainly connective/soft tissues.....It is not necessarily a term ''HOLD'' to be use! |

Dr. Laz'Devitan:I think no1 should be Skin |
| Re: Biology, Chemistry and Physics tutorial thread for jamb by DrLazDevitan: 6:07pm On Jan 07, 2014 |
Influence01: I think no1 should be Skin Yes the skin generally is man's largest organ..... I thought the LIVER......due to usage of ''IN''......as in INSIDE the body!....dat was used by him! |

I beg to disagree wit u on num 2 sir. Rennin which is secreted by d gastric glands in an inactive form prorennin,which is activated by HCl converts caseinogen 'milk protein' into insoluble casein in d presence of calcium ions. @ Op,caseinogen is d soluble form of milk protein while casein is d insoluble form.

Hope dis helps.[/quote] Pls get this......RENNIN helps to make the INSOLUBLE CASEIN....the RENNIN does not make it soluble The solubility of the CASEIN is open to the ZYMOGEN CELLS...which helps in the production of PEPSINOGEN...n finally PEPSIN dat finally make it SOLUBLE! |
