b) They belong to the protein group... i think........ lol c) Enzymes relate to substrate by the "lock and key" model or the "induced fit"model. d) Enzymes are used in the body to increase the persons metabolism by producing both glucose from the substate starch. 4: Specificity is one enzyme attacted to a specific substrate. 5: 2.2?????? 6:Enzymes can be used over because they only needed in small amounts and they are not altered in any way after the reaction. i think.... **: )** 7: a) "activation energy" is the energy required to get a reaction started. b) enzymes speed up the reaction 8: a) enzymes affinity is how much the enzyme wants to attached itself to a substate. b) inhibitors can alter enzymes by denaturing. c) it speeds up the enzymes performance. 9: temp and ph can alter the controlled reactions by either speeding up or slowing down. if it denatures it will speed up however if the temp goes down so will the speed of the reaction 10: 11: a coenzyme is an organic compound that acts with an enzyme to change the rate of reaction where as cofactors are non-protein, additional component that is essential for the normal operating of most enzymes. 12: enzymes are in cleaning products and a majority of drugs. 13: lack of a particular enzyme can cause disease. 14: a) anabolic reaction is the building of larger molecules from smaller molecules. it requires energy to construct the new bonds and often involves dehydration. b) an example of anabolic reaction is ATP. 15: a) catabolic reaction is macromolecules breaking into smaller molecules. b) breaking down of food! 16: 17:a) Hydrolysis is when two molecules come together to produce a water (by bonding OH and H so you have H2O.) Dehydration is doing that in reverse. Breaking the H2O into H and OH and therefore breaking the bond. b)catabolism+dehydration anabolism+hydrolysis c) construction polymers is hydrolysis and breaking them down is dehydration.
 * enzyme questions 2.1**
 * 1) The processes are; respiration for animals, photosynthesis for plants and mitosis for cells.
 * 2) They are referred to as biological catalysts because they speed up chemical reactions.
 * 3) a) Enzymes are proteins that act as biological catalysts which control the metabolism of the cell.
 * temp- the temp can denature the enzyme and then it changes and cannot be used again.
 * ph- can slow down reaction
 * other chemicals-can alter the substrates
 * the amount of reactants and products- this is what the speed of the reaction is based on
 * coenzymes and cofactors- decides whether or not the
 * carbs
 * fats/lipids
 * proteins
 * nucleic acids
