What proteins have a shape that allows only a specific molecule to bind to it?
Proteins that have a specific shape allowing only certain molecules to bind are known as "receptor proteins" or "enzymes." These proteins possess unique active sites or binding sites that are complementary in shape to the specific substrate or ligand they interact with, often described by the "lock and key" or "induced fit" models. This specificity is crucial for biological processes, as it enables precise interactions between molecules, such as hormone-receptor binding or enzyme-substrate catalysis. Examples include insulin receptors and enzymes like amylase.
What happens to the enzyme after it separates from the new molecule?
Once the enzyme has completed its catalytic function and detached from the new molecule, it remains unchanged and can continue to catalyze other reactions. Enzymes are highly specific in their activity and can repeatedly bind to different substrate molecules to facilitate reactions without being consumed in the process.
What do models of carbon backbones show about atoms in a molecule?
Models of carbon backbones show the arrangement of carbon atoms in a molecule. They provide information about how carbon atoms are connected to each other, which can determine the shape and properties of the molecule. Carbon backbones help illustrate the structural framework of organic molecules.
Is it true that the Mercury cyclewater cycle and rock cycle are all models?
Yes, the Mercury cycle, water cycle, and rock cycle are all models that illustrate how different natural processes operate and interact within their respective systems. These models simplify complex interactions to help us understand and predict behaviors in nature, such as how mercury moves through the environment, how water circulates, and how rocks are formed, transformed, and recycled. Each model serves as a framework for studying ecological and geological processes, highlighting the dynamic nature of these cycles.
Creating representations of complex object or processes?
One approach is to use visual aids like diagrams, flowcharts, or infographics to simplify and illustrate complex ideas. Breaking down the object or process into smaller, more manageable parts can also help in creating a clearer representation. Utilizing analogies or real-life examples that are more familiar to your audience can make the concept easier to understand.
What is the Best way to illustrate the way an enzyme interacts with another molecule?
A common and effective way to illustrate the interaction of an enzyme with another molecule is through a lock-and-key model or induced fit model. In the lock-and-key model, the enzyme has a specific active site that fits the substrate like a key into a lock. The induced fit model suggests that the enzyme undergoes a conformational change to better accommodate the substrate. Both models help visualize the specificity and mechanism of enzyme-substrate interactions.
How are the lock and key and induced models similar?
Both the lock and key model and induced fit model are mechanisms used to describe enzyme-substrate interactions. Both models explain how enzymes bind to substrates to facilitate chemical reactions. They both highlight the specificity of enzyme-substrate interactions.

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.
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.
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.
