Metabolism

Metabolism hauv - tus txheej txheem heev. Nws yog tsiag ntawv los ntawm kev siv ntawm cov conversion ntawm lub cev lub tshuaj Cheebtsam. Qhov no txoj kev txhawb rau kev ua si, kev loj hlob, kev loj hlob thiab lub neej ntawm tus kab mob raws li ib tug tag nrho. Engels, piav txog lub metabolism, hais tias qhov no yog qhov tseem ceeb kos npe rau ntawm lub neej, thiab muab sau tseg tias txiav ntawm tus txheej txheem yuav nres thiab lub neej. Nyob rau hauv lub hloov dua siab tshiab ntawm tshuaj Cheebtsam ua zog tsim nyog rau lub neej them nyiaj yug.

Metabolism hauv, raws li yog lub npe hu, muaj ob opposite dab tshwm sim ntawm ib lub sij hawm.

Dissimilation (catabolism) muaj cov tshuaj tiv thaiv cov khoom uas ua los ntawm lub disintegration, ua raws li los ntawm oxidation thiab deducing lwj Cheebtsam. Assimilation (anabolism), assumes tag nrho cov tshuaj uas muaj feem rau cov synthesis ntawm cov lub cev ntsiab thiab lawv assimilation thiab daim ntawv thov kev loj hlob, kev loj hlob, kev ua si.

Metabolism hauv - lub complex zog thiab biochemical dab, uas muab rau cov kev siv ntawm cov khoom noj khoom xyaw rau cov kev xav tau ntawm lub cev, nws muaj raws li qhov yuav tsum tau rau lub zog thiab yas khoom.

Nyob rau hauv lub digestive system, tej (carbohydrates, cov rog, cov nqaijrog thiab lwm cov molecular yuag tebchaw) yog phua rau hauv yooj yim tebchaw (tsawg molecular nyhav). Tsis ntev los no tom qab allergic rau hauv cov ntshav thiab cov ntaub so ntswg yog raug tom ntej transformations: oxidative ntsev, thiab lwm yam aerobic oxidation.

Nws yuav tsum tau muab sau tseg tias nyob rau hauv txhua nyob kab mob tshwm sim ntau yam biochemical dab. Nyob rau hauv qhov uas tsis yog-nyob lub cev tshwm sim muab los ntawm atoms thiab molecules, lawv cov pej xeem.

Nyob rau hauv kev tshawb fawb uas cov kev taw qhia ntawm taug qab rau cov tsiaj nws twb pom hais tias tag nrho cov metabolic dab nyob rau hauv lub hlwb thiab cov nqaij mos tshwm sim tsis tu ncua. Nws tsis qhia tej xyuas ntawm "lub hwj chim" thiab "kev tsim kho" ntawm ib tug qauv. Lawv lub zog yog Attendance yooj yim metabolism.

Nws yog tsim los uas nyob rau nruab nrab ib nrab ntawm tag nrho cov tib neeg cov ntaub so ntswg cov nqaijrog hloov txhua txhua yim caum hnub. Siab enzymes (rau qhov no lub cev yog yus muaj los ntawm ib tug tshaj plaws khaus tshua) yog tshiab txhua txhua ob los yog plaub lub sij hawm. Muaj ib co khoom uas tshiab tshwm sim txhua txhua ob peb kaum feeb.

Metabolic dab muab ib tug dynamic tshuav nyiaj li cas system raws li ib tug sia. Nyob rau hauv tus txheej txheem no ntawm synthesis thiab kev puas tsuaj, kev puas tsuaj thiab tu tub tu kiv balanced. Tsis ncaj ncees lawm metabolism yog nrog los ntawm tsis txaus. Qhov no, nyob rau hauv lem, ua rau mob hauv nruab nrog cev thiab tshuab.

Lub hauv paus ntawm metabolic tshua tshwm sim tawm lub sis ntawm molecules thiab atoms nyob rau physico-tshuaj theem. Qhov no kev sib raug zoo yog kev kawm mus rau tib cov kev cai ntawm animate thiab tswg muaj teeb meem.

Metabolic dab yog inextricably txuas nrog cov kev pauv ntawm lub zog. Nyob kab mob no yog qhib tshuab (nyob rau hauv cov nqe lus ntawm lub zog). Nyob rau hauv lub medium lub lwm tus lub cev, hauv (lub cev) tshwm sim zog tsim. Yog li, lub hav zoov yog ensured thaum ib tug tas mus li lub zog tswv yim los ntawm cov sab nraum.

Rau tib neeg thiab tsiaj ib tug thawj lub zog qhov chaw yog hnub ci tawg. Vim nws raug tshwm sim thiab kev noj haus kev kawm ntawv.

Cov zaub mov yog varied thiab complex muaj pes tsawg leeg. Feem ntau cov nyob rau hauv lub loj cov as-ham - macronutrients. Cov no muaj xws carbohydrates, cov rog, proteins. Cov zaub mov tseem tam sim no thiab mineral Cheebtsam (macronutrients). Cov no muaj xws sodium, phosphorus, poov hlau thiab lwm tus neeg. Tam sim no nyob rau hauv cov zaub mov thiab ib txoj lw ntsiab: selenium, manganese, iodine, zinc, cobalt, tooj liab thiab lwm tus neeg. Ua ke nrog cov vitamins minerals yuav mus rau ib tug hauv chav kawm ntawv ntawm micronutrients.
