Qab Zib yog tsim los ntawm carbon, hydrogen thiab oxygen atoms . Nws yog txoj kev no atoms muaj kev sib txuas uas ua rau txhua hom carbohydrate sib txawv. Nyob rau hauv txhua molecule ntawm lub rooj qab zib nyob ntawd yog: 12 carbon atoms , 22 hydrogen atoms , thiab 11 oxygen atoms . Cov khoom dub hu ua hlawv qab zib !
Ua raws li qhov no, pes tsawg atoms nyob rau hauv tag nrho muaj nyob rau hauv 1 kg ntawm qab zib?
45 atom ua
Tsis tas li ntawd, muaj pes tsawg atoms ua c12h22o11? Lub molecule ntawm sucrose (C12H22O11) muaj 12 carbon atoms, 22 hydrogen atoms thiab 11 oxygen atoms. Cov subscripts kuj qhia qhov piv ntawm cov ntsiab lus. Ib lub kaum os CO2 molecules muaj ib lub kaum os carbon atoms thiab ob lub kaum os oxygen atoms.
Tom qab, lo lus nug yog, dab tsi yog cov ntsiab lus hauv qab zib?
Cov khoom dawb uas peb paub zoo li qab zib yog sucrose, ib qho molecule muaj li ntawm 12 atoms ntawm carbon, 22 atoms ntawm hydrogen , thiab 11 atoms ntawm oxygen (C12H22O11). Zoo li tag nrho cov tebchaw ua los ntawm peb lub ntsiab lus, qab zib yog a carbohydrate.

Muaj pes tsawg guanine bases puas yog 50 lub hauv paus khub ob txoj hlua DNA 100 bases tag nrho muaj yog tias nws muaj 25 adenine bases?
Yog li, muaj tag nrho ntawm 25 + 25 = 50 adenine thiab thymine hauv tag nrho. Qhov ntawd tawm 100− 50 = 50 seem hauv paus. Nco ntsoov tias cytosine thiab guanine daim ntawv cog lus nrog ib leeg, thiab yog li lawv sib npaug ntawm cov nyiaj. Tam sim no peb tuaj yeem faib los ntawm 2 kom tau txais tus lej ntawm guanine lossis cytosine hauv paus
