Enzymes and their specific substrates fit together like a lock and key. Enzymes have specific binding sites that perfectly match the shape of their substrates, allowing for efficient catalysis of specific chemical reactions. This lock-and-key model is essential for the specificity and efficiency of enzyme-substrate interactions.

Name the flattened cells that fit together like tiles?
The flattened cells that fit together like tiles are called squamous cells. They are found in tissues like the skin, lungs, and blood vessels, where their shape allows for efficient gas exchange and barrier protection.
How are substrates like keys and enzymes like locks?
Substrates are molecules that fit into the active site of an enzyme, much like a key fits into a lock. The active site of the enzyme has a specific shape that only allows substrates with a complementary shape to bind, similar to how a lock only opens with the correct key. This specificity ensures that enzymes only catalyze specific reactions with specific substrates.
Which statement describes the currently accepted theory of how an enzyme and its substrate fit together?
The currently accepted theory is the induced fit model, which states that the enzyme undergoes a conformational change upon binding with its substrate in order to create a complementary fit. This model accounts for the specificity of enzyme-substrate interactions and how the active site of the enzyme can adjust to accommodate the substrate.
Will the fat molecule fit together as pieces in a puzzle?
No, fat molecules do not fit together like pieces in a puzzle. Instead, they are composed of long chains of fatty acids and glycerol molecules that are linked together to form a triglyceride structure. These molecules are generally packed together in a more random and fluid arrangement.
Name the flattened cells important in protection that fit together like tiles?
Squamous epithelial cells are the flattened cells important in protection that fit together like tiles. These cells create a tight barrier that helps protect underlying tissues from damage and provide a smooth surface for processes like gas exchange.

How is a substrate and its enzyme like a lock and key?
A substrate and its enzyme are like a lock and key because they have specific shapes that fit together perfectly. Just like a key must fit exactly into a lock to open it, the substrate must fit into the enzyme's active site for a reaction to occur. This specific interaction ensures that only the correct substrate is acted upon by the enzyme.
What is the difference between the lock and key model versus the induced fit model of the enzyme substrate complex?
The lock and key model means that the substrate must perfectly fit the enzyme, and the enzyme does not change. The induced fit model is different as when the substrate fits together with the enzyme, the enzyme itself will change to either join substrates together or break a substrate down.
What is the difference between the key and lock theory and the induced fit model?
The key and lock theory suggests that enzymes and substrates fit together like a key fits into a lock with a rigid, non-flexible active site. In contrast, the induced fit model proposes that the enzyme's active site can change its shape to accommodate the substrate, thus providing a more dynamic interaction between the enzyme and substrate.
What is the name of the hypothesis that helps explain enzyme functioning?
The lock and key hypothesis explains enzyme functioning. It suggests that enzymes and substrates fit together like a lock and key, with specific enzyme-active sites binding to specific substrates to catalyze reactions.
What hypothesis by alfred wegener explains why contients seem to fit together?
They all fit together like a puzzle.
What is the difference between hydrophilic and Hydro phobic?
Hydrophilic substances are attracted to water and tend to dissolve in it, while hydrophobic substances repel water and do not dissolve easily in it. Essentially, hydrophilic means "water-loving" and hydrophobic means "water-fearing."
Do enzymes change shape to move substances across the plasma membrane?
No, enzymes do not change shape to move substances across the plasma membrane. Enzymes facilitate chemical reactions by lowering the activation energy required for the reaction, but they do not actively transport substances across the membrane. Transport proteins handle the movement of substances across the plasma membrane.
What is the example of induce fit and lock and key theory?
An example of the induced fit theory is when an enzyme undergoes a conformational change to better accommodate the substrate upon binding. On the other hand, the lock and key theory suggests that the enzyme's active site is already in the correct shape to fit the substrate like a lock and key.
Name the flattened cells that fit together like tiles?
The flattened cells that fit together like tiles are called squamous cells. They are found in tissues like the skin, lungs, and blood vessels, where their shape allows for efficient gas exchange and barrier protection.
How do regions of the US work together?
