Question | Answer |
A biological catalysts that facilitate specific chemical reactions | Enzyme |
The molecule upon which an enzyme acts | Subtrates |
Region of an enzyme surface to which a specific state of substrates binds | Active site |
Most enzymes are proteins | Made of Amino Acids |
Enzymes required by all chemical processes in organisms | Respiration, growth, photosynthesis, movement, etc) |
Enzymes control the rate of Metabolic in the body | Metabolic are chemical reactions |
Enzymes lower Activation Energy | Activation Energy = energy needed to start a reaction |
Enzymes weaken chemical bonds so molecules can be | Made or broken down in the body |
Enzymes react on | SUBSTRATES |
Are Enzymes unspecific or specific | SPECIFIC |
Enzymes are REUSABLE | NOT USED UP IN A REACTION |
The substrate TEMPORARILY fits into this site during the metabolic reaction | ACTIVE SITE |
What is like a poison that can BLOCK AN ACTIVE SITE | INHIBITORS |
INHIBITORS often have what can of ending to the word | -ASE |
What are SUCRASE, LIPASE, PROTEASES, CATALASE AND AMYLASE | INHIBITORS |
Sucrose (Table Sugar) | SUCRASE |
Lipids (fats & oils) | LIPASE |
Proteins | PROTEASES |
Breaks down waste H202 made by cells | CATALASE |
Exists in human saliva breaks down starch (amylose) | AMYLASE |
Bacteria, protists, fungi, plants, and animals are PRODUCED NATURALLY | by ALL organisms |
ENZYMES Must have the correct shape to do their jobs | GLOBULAR in SHAPE |
UNFOLDING an enzyme so its shape changes and it NO LONGER WORKS | DENATURATION |
A FACTOR that DENTAURE enzymes include: | Change in PH (need PH7 neutral to work) |
A FACTOR that DENTAURE enzymes include: | Extreme temperature changes (require body temperatures to work. |
A FACTOR that DENTAURE enzymes include: | Excess IONS such as salts |
WITHOUT ENYZYMES OUR INTESTINES WOULD TAKE WEEKS TO | DIGEST OUR FOOD |
WITHOUT ENZYNMES OUR MUSCLES, NERVES, BONES WOULD NOT WORK PROPERLY | SOON DEATH WOULD RESULT |
1 0F 4 steps for a process of an enzyme working~ An ENZYME and a | SUBSTRATE are in the same area |
2 0F 4 steps for a process of an enzyme working~ The enzyme grabs onto the substrate with a special area called | ACTIVE SITE |
2 0F 4 steps (continued) for a process of an enzyme working~ the Enzyme active site changes shape caused or induced by the specific substrate | Induced fit |
3 0F 4 steps for a process of an enzyme working~ the process occurs where the substrate is changed | CATALYSIS |
4 0F 4 steps for a process of an enzyme working~ What is released from the enzyme's active site | Product (new substance) |
