Kev Taw Qhia. Active cov chaw yog cov cheeb tsam feem ntau nyob rau saum npoo ntawm cov enzymes tshwj xeeb ua qauv los ntawm xwm thaum lub sij hawm evolution uas yog catalyze ib qho tshuaj tiv thaiv los yog lub luag hauj lwm rau substrate kev khi . Cov qhov chaw nquag tuaj yeem ua tau, yog li ntawd, muab faib ua ob ntu, uas suav nrog catalytic site thiab substrate khi qhov chaw (1).
Tsis tas li ntawd, koj yuav nrhiav tau qhov chaw nquag ntawm ib qho enzyme li cas?
Hauv biology, lub qhov chaw nquag yog thaj tsam ntawm ib enzyme qhov twg substrate molecules khi thiab raug tshuaj lom neeg cov tshuaj tiv thaiv. Cov qhov chaw nquag muaj cov residues uas tsim ib ntus daim ntawv cog lus nrog lub substrate (binding qhov chaw ) thiab residues uas catalyze cov tshuaj tiv thaiv ntawm cov substrate (catalytic qhov chaw ).
Qhov thib ob, lub luag haujlwm ntawm qhov chaw ua haujlwm ntawm enzyme yog dab tsi? Lub substrate yog cov khoom los yog cov molecule uas yog ib qho enzyme ua haujlwm . Cov hnab ris no muaj cov qhov chaw nquag , uas yog thaj tsam ntawm ib enzyme qhov twg lub substrate khi thiab cov tshuaj tiv thaiv yuav siv sij hawm qhov chaw . Hauv qhov chaw nquag , cov amino acids enzyme protein yuav khi rau lub substrate.
Kuj kom paub yog, koj ua li cas thiaj nrhiav tau qhov chaw nquag ntawm cov protein?
Saib cov no cov chaw nquag , zais tag nrho cov khoom thauj khoom rau hauv PyMol los ntawm kev siv cov lus txib "hide". Sawv cev tag nrho protein ntau nrog tus sawv cev saum npoo, teeb tsa nrog 50% pob tshab. Xaiv qhov khoom protein ntau molecule, qhia? nto puv tag nrho protein ntau molecule rau saum npoo sawv cev.
Dab tsi amino acids feem ntau pom nyob rau hauv lub chaw ua haujlwm?
beta-Alanine - Tsuas yog ib txwm tshwm sim beta amino acid . Arginine - Amino acid feem ntau siv rau ntawm cov chaw nquag ntawm enzymes. Asparagine - Amide derivative ntawm aspartic kua qaub . Aspartic Acid - Qhov tseem ceeb nruab nrab ntawm citric kua qaub lub voj voog.

Yuav ua li cas koj txiav txim siab yog hais tias ib tug muaj nuj nqi muaj ib tug kab rov tav tangent?
Kab rov tav kab muaj txoj kab nqes ntawm xoom. Yog li ntawd, thaum lub derivative yog xoom, cov kab tangent yog kab rov tav. Txhawm rau nrhiav cov kab kab rov tav tangent, siv qhov derivative ntawm txoj haujlwm los nrhiav qhov xoom thiab ntsaws lawv rov qab rau hauv qhov sib npaug qub
Yuav ua li cas koj txiav txim siab qhov kawg tus cwj pwm ntawm ib tug polynomial?
Tom qab ntawd, tus coefficient ntawm lub sij hawm txhuas yuav txiav txim siab tus cwj pwm ntawm polynomial. Yog tias qhov sib txawv (cia hais tias X) yog qhov tsis zoo, ces X hauv lub sijhawm siab tshaj plaws tsim qhov tsis zoo. Peb mam li muab cov coefficient ntawm lub sij hawm coj mus rau qhov tsis zoo los txiav txim qhov kawg tus cwj pwm
Yuav ua li cas koj txiav txim siab npaum li cas ntawm cov kua qaub uas yuav tsum tau neutralize lub hauv paus?
Kev daws qhov teeb meem Acid-Base Neutralization Kauj Ruam 1: Muab xam cov moles ntawm OH-. Molarity = moles / ntim. moles = Molarity x Volume. moles OH- = 0.02 M/100 milliliters. Kauj ruam 2: Xam qhov ntim ntawm HCl xav tau. Molarity = moles / ntim. Volume = moles/molarity. Volume = moles H+/0.075 Molarity
Yuav ua li cas koj txiav txim siab ib tug mineral streak?
Mineral Streak Streak yog xim ntawm cov ntxhia thaum itis crushed rau hmoov. Txoj hauv kev yooj yim tshaj plaws los txiav txim siab cov pob zeb hauv av yog txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm Minerals nrog ib tug hardness tsawg tshaj li 7 yuav tawm ib streak. Rau ntau tus streak yuav dawb, soalways saib kom zoo
Yuav ua li cas koj txiav txim siab uas yog tus nqi txiav txim kauj ruam?
Tus nqi txiav txim siab kauj ruam yog kauj ruam qeeb tshaj plaws ntawm cov tshuaj tiv thaiv tshuaj uas txiav txim siab qhov nrawm (tus nqi) uas tag nrho cov tshuaj tiv thaiv ua tiav. Teb Tus nqi txiav txim kauj ruam yog kauj ruam thib ob vim nws yog kauj ruam qeeb. 2NO + 2H2 → N2 + 2H2O. Cov intermediates hauv cov tshuaj tiv thaiv no yog N2O2 thiab N2O
