Bacteria are grouped into two kingdoms and two domains which are equivalent. select the one showing the correct pairings below (kingdom: domain). archaebacteria : bacteria and protista: prokaryotes archaebacteria : archaea and eubacteria : bacteria archaea : bacteria and eubacteria : protista archaea : eubacteria and bacteria : archaebacteria

a neutral ph of 7 and normal organism temperature is needed for a certain enzyme to be effective.  

what would happen to the enzyme if the ph and/or temperature fluctuate greatly from the norm?  

a.the enzyme’s hydrogen bonds will break.  

b.the activation energy will increase.  

c.more product will be formed.

d.the ideal temperature and ph for the enzyme function will decrease.  

when a reversible reaction is occurring in both directions at the same rate; the products and reactants do not change in concentration. a chemical reaction where the compound is broken into its constituent parts.
