E like me ka poe i kaheaia liluwelo catalysts? ʻO nā'ūhū like liluwelo catalysts

Ke kanaka kino ua kapaia ka biochemical hola ihola ia i loko o makehewa. Ma hope o nā mea a pau, o kela mea keia minuke o ia hana tausani, haneri o nā tausani o ka'okesaside, cleavage, ke ola a me ka 'ē aʻe reactions. E apono 'ia e ke hoomau aku me ia i ka mämä holo nui, ka hoʻolako' kēlā halepaahao me ka ikehu, ka ai a me ka oxygen?

Ka manaʻo o na catalysts

Ua'okanikaʻole a me ke aloha kemika e hoʻomano hoʻohana kūikawā waiwai hiki ke accelerating Nine Inch reactions i loko o nā tausani, a me kekahi manawa miliona o ka manawa. Ka inoa o kēia mau i huiʻia - "catalysts". Ma 'okanikaʻole kemika mea metala oxides, platinum, kala, nikala a me na mea e ae.

Lākou ka papa kuhikuhi hana - i ke kahua o ka? Aiaiiuie eiiieaenu me ka naoh o ka i komo, ma ua hakumakuma o ka ho'ā hope ikehu o ke kaʻina ua lawe mai kekahi mau manawa wikiwiki. Mahope, i ka luna 'decomposes a me ka laulā hiki ke ho oholo wae mai o ka hōʻeleu i loko o ka ia qualitative a laupaʻi haku mele' ana e like me ma mua o ka hoʻomaka 'ana o ke kaʻina hana.

Aia he mau koho no catalytic reactions:

• homogeneous - ka accelerator, a me ka i komo i loko o ka hookahi moku'āina o aggregation;
• heterogeneous - accelerator, a me ka i komo i loko o kaʻokoʻa Hawaii, he mea ka mau '.

Eia kekahi, he mea kue ole o na hui - nā mea kūpale. Ka mea, i pahuna ma ka meheu o ia i ka mea e pono ai reactions. No ka laʻana, ka mea hiki ke emi ka nui o ka manawa ma ka kahua o ka popopo.

Liluwelo catalysts i inherently okoa mai ka'okanikaʻole, a me ka waiwai o ko lākou hou kekahi. No laila, i ka noho ana nenoai catalysis kekahi.

Nā'ūhū - He aha ka mea?

Ua Ua hoao ia ina e ole lawe i ke kanawai o ka kūikawā waiwai e hōʻeleu i kekahi keʻano o ka hanaʻana mai loko ola nenoai, ia mea IeAUPIIe, IAa IO he ohia i loko o ka'ōpū makemake e hōʻuluʻulu manaʻo no e pili ana i mau lā. No ka mea nui o ka manawa e ua hoʻomaka na keʻano o ka hanaʻana o ka palaho a me ka awi aku ai intoxication. Naʻe, i kēia 'ole e hana, a me ka hua ua piha hoʻokō' ano a me ka hapalua hola. Hoʻokō 'i liluwelo catalysts, i mea nui i hiki mai i loko o ka haku mele' ana o kēlā me kēia meaola. Akā, i ka mea a ka mea mau a me ka mea i kekahi hana ua ka nānā 'ana?

Liluwelo catalysts o kumuʻiʻo ano - i nā'ūhū. Lākou mau kumu - o ka luna 'mall hoʻolālā, ai ka helu ana o kekahi waiwai. Aloha i, i kēia kū hoʻokahi nā polokina hiki ana o ua hakumakuma ka ho'ā hope ikehu o keʻano o ka hanaʻana i loko o ola meaola a hoʻokō ia i ka uku oi aku i ka mau aiee o kekahi mau miliona manawa.

Aia mau examples lehulehu o ia nā lātoma:

• catalase;
• amylase;
• oxidoreductases;
• monakō koko oxidase;
• lipase;
• invertase;
• lysozyme;
• protease a me na mea e ae.

Pela, ua hiki ke manao nei makou, na nā'ūhū - liluwelo catalysts o ke kumuʻiʻo maoli ana, a hana like ikaika accelerators, ka ho'ā na tausani o keʻano o ka hanaʻana i ka noho ana meaola me ke kiʻekiʻe loa māmā. Kā lākou hana ua muli ma ka digestion,'okesaside, ka ho'ēmiʻana.

Mea like a me ka'okanikaʻole catalysts kumuʻiʻo

ʻO nā'ūhū like liluwelo catalysts i ka waiwai kekahi like i ka'okanikaʻole. I ka poe nā ke kēia:

1. Thermodynamically hiki wale hōʻeleu i ke naoh.
2. Ua aʻole e pili mai i ka 'oni iki o ke Nine Inch equilibrium ma ka equilibrium nenoai, a me ka ia māmā nā mua a me ka hoole.
3. E like me ka hopena, i loko o ka naoh i nā huahana wale, ka hōʻeleu mea,ʻaʻole ma waena o lākou.

Eia naʻe, 'Aʻohe wai iaʻu, mai aʻo Kīwala'ō, eia kekahi hiʻona o na nā'ūhū.

Oko ao ke kaumaha ma muli o kaʻano

Liluwelo catalysts i kekahi mau kekahi hiʻona:

1. Ke kiʻekiʻe loa o ka selectivity. A laila kekahi kumuʻiʻo mea hiki ke haʻalele wale i kekahi mau 'naoh a like hui. Loa pinepine hana noaia "'ūhū - kūpapakū mea he kaʻina hana."
2. Ka loa kiʻekiʻe degere o ka haʻawina, no ka mea, i kekahi mau ʻano o nā polokina e hiki e hōʻeleu i ke naoh miliona o ka manawa.
3. Nā'ūhū e loa e kaukaʻi ma? Aneie olelo. He hana wale nō i loko o ka kekahi ana wela huahelu. Ua Ua hoi ikaika 'ole ma o ka pH. Aia He He hālawa hōʻike ana i ka palena iki cia, i kā mākou a me kaʻoi loa ka lākiō. No kēlā me kēia'ūhū.
4. Aia i kūikawā hui kapa effectors, mea i hiki ke inhibit i ka liluwelo ano o ka hōʻeleu paha, conversely, i ka maikaʻi keiki ma luna o lākou.
5. Ke kūpapakū ma i ka'ūhū hana, e e pololei kekahi. Aia ka he kumumanaʻo, a ua kapaia ka ki a me ka laka. Ua wehewehe i ka'ūhūʻano papa hana o ka hana ma luna o ka kūpapakū. Ka hōʻeleu, e like me ka kī, ua i loko iho i loko o ka kūpapakū i konaʻeleu paena, a me ka naoh ua hoʻokumu pū.
6. Ma hope o ke kaʻina hana o ka'ūhū ua hapa 'ia' ai ihola ia i luku aku.

Penei, ka mea, ua maopopo i ka waiwai ka loa nui kumuʻiʻo catalysts no ka noho ana meaola. Eia naʻe, kā lākou hana mea paha i kekahi mau rula, a hoopaaia 'ia.

I ka like o ka catalysis ma ke kula

E like me kekahi hapa o ka laulā maʻamau aʻo like catalysts ma ka kemika a me ka kālaimeaola. ka mea, ua aʻo kemika haʻawina ma ka hua'ōlelo o nā mea i hoʻohana no ka hanalima syntheses, e loaa i ka laulāʻano o nā huahana. liluwelo catalysts ua noʻonoʻo ma ka kālaimeaola papa. Grade 9 komo ai i ke ao o ka hakakino kālaimeaola a me ka biochemistry hoʻokumu paʻaʻana. Nolaila, ia mea ma keia pae o ka hoʻonaʻauao , nā haumāna loaa walaʻauʻana ike ana pehea nā'ūhū o kaʻeleu waiwai i loko o ke kino o ka mea ola.

I nā haʻawina a mālama 'ho okolohua e hookupaa aku ana i ka Nine Inch ha awina o kēia mau waiwai i kekahi ka mahana a me ka pH papa koa:

• like o ke kanawai o ka hydrogen peroxide like me ka hōʻeleu no ka maka, a hoolapalapaia carrots;
• hopena ma luna o ka mōhaiʻai (wela ia, a heʻiʻo maka nō), uala a me nā huahana.

ʻO nā'ūhū i loko o ke kanaka kino

Kēlā me kēia haumāna, ka poe i hui me ka hana pono laina awelika loulou ho okumu ike pehea kapaia liluwelo catalysts. Nā'ūhū i loko o ke kino, ua pololei kekahi specialization. No ia mea, he mea hiki i ka inoa i ka catalyzing agena no kēlā me kēia kaʻina.

No laila, na nā'ūhū a pau o ke kino hiki ke maheleia i loko o kekahi mau pūʻulu.

• oxidoreductase, e laʻa me, catalase a ka waiʻona dehydrogenase;
• transferase - Kenaza;
• hydrolases nui no ka digestion: pepsin, amylase, lipoprotein lipase, esterase a me ka mea e like;
• ligase, e laʻa me, he DNA polymerase;
• isomerase;
• lyase.

Mai a pau o kēia mau hui i kumuʻiʻo ma ke ano maoli, e like me ka luna 'ana o nā wikamina i loko o ka haku mele' ana, ke kuni ua fraught denaturing i ka 'ole, a nolaila, i ka hoopau ana o nā mea a pau biochemical reactions. Ma keia hihia, ke kino e kokoke i ka make. Nolaila, kiʻekiʻe kino mahana ua koi 'ia e lawe mai ia i maʻi.

E ho ohana i ke kumuʻiʻo catalysts ma ka hana

Pinepine, e hoʻohana i nā nā'ūhū i loko o kekahi mau hana :

• Nine Inch;
• lole;
• ai.

Ma ka shelves oe ke ike cleansers a me detergents me nā'ūhū maʻiʻo - keia mea na nā'ūhū e hoʻoikaika i ka pono o ka holoi holoi.

He aha e liluwelo catalysts?

Overestimate kā lākou waiwai, he pilikia. Ma hope o nā mea a pau, aole lakou i wale ae ola meaola e ola, hanu, ai, hana pūnao, akā, i haawi mai i ka manawa, e hoopau aku i ka hanalima neoneo, loaa ka lapaʻauʻia, e hoomalu ai e hoopakele i ko lakou ola kino, a me ka kaiapuni.
