enzymes and substrates
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.
Enzymes have an active site that is specific for a substrate - therefore enzymes only work when the right substrate is present. The surfaces of the enzyme and the substrate fit together - like a lock and key - allowing the enzyme to fulfil its function. The theory of "induced fit" is more widely accepted - it is similar, but the enzyme shape changes to accommodate the substrate.
There is an enzyme explanation whose specificity states that an enzyme and its substrate possess specific complementary geometric shapes that fit exactly into one another. This is the lock and key explanation.Ê
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.
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.
Interlock
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.
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.
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.
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.
They all fit together like a puzzle.
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.
Enzymes and the substrates they work on fit like a lock and key, if you change the shape of the key, the lock won't open. An enzyme whose shape changes is no longer able to activate the reaction of the substrate.
Hydrophilic substances incline to get together with polar substances like water or some ions while hydrophobic substances tend to get together with nonpolar substances like organic compounds. You can understand these identities by imagining that the more two substances are likely in polarity, the eaiser they get together, because they are fit in electic charges so that the energy of the mixture system is lower. Though this theory is rough, hope it can help you underdstand the the difference between hydrophilic and hydrophobic.
