What happens to the enzyme after it separates from the new molecule?
It returns to its original shape, and is reused. Look up the 'lock and key' and 'induced fit' models.
When can models be used to collect data and make predictions?
when models chave been validated with evidence
Creating representations of complex object or processes?
models are the answer
What are some limitations of models?
Some limitations of models are not to change what the model is asking you.
Why do scientistsuse models to study things?
Scientist use models to study things because models are sometimes easier to use than trying to study things in a natural environment.
Why would the accelerator on a Chevy s 10 blazer stick?
* Binding pedal linkage * Binding carburetor linkage (carb models) * Binding throttle body linkage or butterfly (fuel-injection models)

What types of binding machines are available at Office Depot?
Office Depot carries a variety of comb style binding machines, punch binding machines, and a uni-binding machine. Some models are manual, and others are automated.
When was the spiral binding machine developed?
in France - approximately in 1940. see http://www.bindingstuff.net/combbinding.html for current models of comb binding equipment
What is the average price of a Fellowes binding machine?
Fellowes makes the full spectrum of binding machines from plastic comb binding machines to the professional thermal models. The plastic comb binding machines can be bought for about $100. The thermal binding machines sell for $500 and up.

What factors affect the rate at which an enzyme works?
Very basically: * specificity - the better 'fit' the substrate, the higher the rate of catalysis. * temperature - higher temp = more kinetic energy = faster eaction. However, too high and the enzyme becomes irreversibly denatured and will not work at all. (denatured = the folding of the peptide chains are disrupted, meaning that the shape changes and the substrates no longer fit). The temperature at which the reaction occurs at the fastest rate is called the optimum temperature. * pH - enzymes have specific pH that they work best at (the optimum/optimal pH), as pH can also affect the bonds holding the tertiary structure together (especially ionic bonds), denaturing the enzyme. * concentration of enzyme and substrate - rate of reaction is proportional to the enzyme/substrate concentration. However, at a given enzyme concentration, substrate conc is proprtional to rate up to a point when the enzyme becomes saturated and the rate remains constant. * cofactors/coenzymes - some enzymes require interaction with other molecules to show full catalytic activity. * inhibitors - the presence of an inhibitor lowers the rate of catalysis. There are competitive, uncompetitive, non-competitive and mixed inhibitors, they can bind reversibly or irreversibly, at the active site or an allosteric site... That's a very simple, school textbook answer (and I may have forgotten a factor?). For more detail, any biochemistry textbook should be able to help.
The function of models in science?
To illustrate something in larger or smaller scale so one can easily visualize the whole picture
What are some good examples of binding systems?
The website Office Depot has many types of binding systems available to businessmen. They come in a variety of different models with prices ranging from $70 to $200.
Astronomers are still uncertain about how the Earth's atmosphere formed How does this illustrate the workings of the scientific method?
The problem with our current models is that there is not enough data to allow us to determine which of the popular models are best. A model may come to be accepted if new data supports it, while at the same time contradicting other models.
