Cytoplasm, qhov seem ntawm cov khoom ntawm lub cell nyob rau hauv lub plasma daim nyias nyias , tsis suav nrog thaj tsam nucleoid lossis nucleus, uas muaj cov kua dej hu ua cytosol thiab cov organelles thiab lwm yam khoom uas tau muab tshem tawm hauv nws. Ribosomes, cov organelles uas protein synthesis tshwm sim.
Ua raws li qhov no hauv kev txiav txim siab, cov qauv dab tsi muaj nyob hauv txhua lub cell nyob?
Peb lub ntsiab lus tseem ceeb ntawm ib tsob nroj lossis tsiaj txhu cell yog:
- PLASMA MEMBRANE / CELL MEMBRANE. Structure - ib txheej bilipid membrane uas muaj cov proteins thiab carbohydrates.
- CYTOPLASM.
- NUCLEUS.
- 1."
- RIBOSOMES.
- GOLGI BODY / APPARATUS.
- LYSOSOMES.
- MITOCHONDRIA.
Ib yam li ntawd, cov qauv cellular twg yog qhov zoo rau tag nrho peb lub neej? Phospholipid bilayer cell membrane.
Tsis tas li ntawd, dab tsi yog cov khoom tseem ceeb hauv txhua lub hlwb?
Cells yog qhov tsawg tshaj plaws denominator ntawm lub neej. Ib txhia hlwb yog cov kab mob rau lawv tus kheej; Lwm yam yog ib feem ntawm cov kab mob multicellular. Txhua lub hlwb yog tsim los ntawm tib yam loj Cov chav kawm ntawm cov organic molecules: nucleic acids, proteins, carbohydrates, thiab lipids.
Puas yog txhua lub hlwb muaj cov qauv zoo ib yam?
Txawm tias muaj yog ntau yam sib txawv ntawm hlwb , lawv tag nrho qhia cov yam ntxwv zoo sib xws. Txhua lub hlwb muaj ib cell organelles organelles, cytoplasm, thiab DNA. 1. Txhua lub hlwb yog nyob ib puag ncig ib cell daim nyias nyias.

Ob qhov tseem ceeb ntawm lub voj voog ntawm tes yog dab tsi thiab dab tsi tshwm sim rau lub cell hauv txhua theem?
Muaj ob theem tseem ceeb hauv lub voj voog ntawm tes. Thawj theem yog interphase thaum lub cell loj hlob thiab replicates nws DNA. Qhov thib ob yog theem mitotic (M-Phase) thaum lub sijhawm cell faib thiab hloov ib daim qauv ntawm nws cov DNA mus rau ob lub hlwb zoo tib yam
Nyob rau hauv dab tsi ntawm lub cell puas cellular respiration tshwm sim?
Mitochondria
Dab tsi yog 2 qhov tseem ceeb ntawm lub voj voog ntawm tes thiab dab tsi tshwm sim rau lub cell hauv txhua theem?
Cov xwm txheej no tuaj yeem muab faib ua ob qhov tseem ceeb: interphase (hauv nruab nrab ntawm kev sib faib theem ua pawg G1 theem, S theem, G2 theem), thaum lub xov tooj ntawm tes tsim thiab ua nrog nws cov haujlwm metabolic; mitotic theem (M mitosis), thaum lub sij hawm lub cell yog replicating nws tus kheej
Tus qauv qauv yog dab tsi Qhov txawv ntawm tus qauv qauv thiab tus qauv molecular yog dab tsi?
Cov mis mos molecular siv cov cim tshuaj thiab cov ntawv sau npe los qhia cov naj npawb ntawm cov atoms sib txawv hauv cov molecule lossis compound. Ib qho empirical formula muab qhov yooj yim tshaj plaws, tag nrho tus lej piv ntawm atoms hauv ib qho chaw. Cov qauv qauv qhia txog kev sib koom ua ke ntawm cov atoms hauv cov molecule
Nyob rau hauv dab tsi organelle yog pyruvate oxidation nqa tawm nyob rau hauv ib lub cell?
Pyruvate oxidation cov kauj ruam Pyruvate yog tsim los ntawm glycolysis nyob rau hauv lub cytoplasm, tab sis pyruvate oxidation tshwm sim nyob rau hauv lub mitochondrial matrix (hauv eukaryotes). Yog li, ua ntej cov tshuaj tiv thaiv tuaj yeem pib, pyruvate yuav tsum nkag mus rau mitochondrion, hla nws daim nyias nyias thiab tuaj txog ntawm matrix
