| A | B |
|---|
| Ionic bond- | positive and negitive ions are attracted to eachother - like magnets (Na+ Cl - ) |
| Covalent bond- | 2 atoms sharing 1,2 or 3 electron pairs |
| Enzyme-substrate complex | the process of substrates binding to the active site in order for molecules to interact with eachother and a product to be formed. |
| Definition of photosynthesis- | converts light energy into chemical energy to build plant structure out of sugar |
| Def. of C.R. | Decomposition of sugar into energy controlled by enzymes. Opposite of photosynthesis |
| Active site- | a small region of the enzyme that attracts and holds the substrate |
| Metabolism | the sum of all chemical changes in an organism |
| Substrate- | chemicals on which the enzyme acts |
| Catalyst- | a chemical that speeds up a reaction between other chemicals and emerges unchanged |
| Ion- | an atom that has either gained or lost 1 or more electrons giving a positive or negitive charge |
| Enzymes- | a protein molecule that acts as a catalyst in a specific biological reaction |
| How is CR like burning fuels | 1) food and fuels are both Co2 H20 and O2 #2) co2 and h2o are both bi products. Different becuase food is burned slower and at a lower temp. |
| What is adp/atp? | energy is released with the 3rd phosphate group is broken off that released E helps the cell do it's work. What attaches the adp to another p is enzymes |
| Ionization: | an uncharged particle becomes charged |
| 2nd law of thermodynamics | natural processes tend to proceed in a way that increases the disorder (entropy) of a system. Energy is required to maintain order. |
| Chemical reaction | the making or breaking of chemical bonds, substances interact with eachother and new substances are formed. |
| How many arrows are there in the carbon cycle? | 20! (but if you aren't me then maybe you count diff.) |
| Whats the importance of enzymes in CR. | to be catalysts and to add another phosphate to adp and break atp into adp...but i may be wrong |
| steps in photosynthesis: | Light E- absorbed my chloraphyl Co2- absorbed by stomata H02- absorbed from roots. Plants split water into hydrogen and oxygen and combines with Co2, then releases O2. |
| stomata | holes that absorb co2 |
