14997573419 | What are digestive enzymes based in? | Protein | 0 | |
14997576035 | Enzymes | Catalysts for chemical reactions in living things | 1 | |
14997578097 | lipase | digestive enzyme that is made in the pancreas and breaks down lipids in the small intestine. - highest rxn rate in basic environment | 2 | |
14997579780 | Pepsine | digestive enzyme that breaks down proteins in stomach. - highest rxn rate in acidic environment | 3 | |
14997581687 | lipase digestion reaction | triglycerides --lipase--> glycerol + fatty acids | 4 | |
14997585631 | pepsin digestion reaction | large polypeptides --pepsin--> smaller polypeptides + amino acids | 5 | |
14997595943 | What is the effect of exposing an enzyme to pH outside of its optimal range? | - denaturation - unfolds proteins, reducing its chemical rxn efficiency and becomes useless as a catalyst. | 6 | |
14997600591 | What pH values denature lipase? | Below 4 and above 12 | 7 | |
14997603440 | What pH values denature pepsin? | Above 5 | 8 | |
14997606434 | Enzyme structure and function | Altered enzyme structure prevents the enzyme from functioning properly - structure of enzymes are changed to tolerate different environments | 9 | |
14997609133 | antacid effect on digesting proteins | temporarily denatures digestive enzyme | 10 | |
14997610316 | antacid | drug that neutralizes stomach acid | 11 | |
14997612467 | optimum temp. for amylase? | 35 degree C - important because this is the human body temp! | 12 | |
14997618127 | coenzyme | an organic cofactor - binds to protein strands of enzyme, changing its shape so that it is ready to receive the substrate molecule. - without it, the coenzyme would not be able to attach to substrate | 13 | |
14997623009 | inhibitors | An agent that slows or interferes with a chemical action - reduce rxn rate by binding to protein and either blocking the spot where substrate will bind or make enzyme shape incompatible with substrate. | 14 |
