What is the definition of the word interlocking?
The word 'interlocking' is used to denote when two or more items are joined. This could be by overlapping or with one item having projections which fit into a recess on another item.
What fit for purpose means?
Fit for purpose means good enough to do the job it was made to do.
What is fit in mechanical engineering?
Fit refers to how tight the clearance is between a shaft and hole. Fits range from loose, free, medium, transitional to interference fit. In metric the system ranges from E6 being very loose to R7 tight interference fit.
What is the simple machine that developed into drill bits?
A screw would fit this description. Although it should be noted that from a geometric standpoint a screw may be considered as an inclined plane (another simple machine) wrapped around a cylinder.
Why is necessary to hammer after welding a joint?
it's not. Welders do use a chisel/hammer to knock the slag off, but a wire brush will do the same thing. Some welders do use a hammer to align their fit-up when the tack is still hot, but not after they have welded. If the slag is left on, it may cause expedited corrosion, this is why it should be cleaned, but in most top quality shops - a wire brush is used. It is necessary to hammer a weld joint after welding CI to CI as the induced stress are relieved to a large extent and also the cracking can be avoided in case of CI
What is the induced fit theory?
The induced fit theory proposes that the active site of an enzyme changes its shape upon binding with the substrate. This change is induced by the interaction with the substrate, leading to a more precise fit and optimal conditions for catalysis to occur. This theory suggests that the binding of a substrate to an enzyme is a dynamic process rather than a static lock-and-key model.
How does the induced fit model help to explain non-competitive inhibition?
The induced fit model is the theory that instead of enzymes and substrates fitting exactly together, as in the lock and key model, the enzyme changes shape around the substrate to bind with it. Non-competitive inhibition is where the inhibitor does not fit into the active site, but into another site on the enzyme instead, which changes the shape of the active site.
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.
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 are the two theories that explain enzyme specificity?
The lock and key theory and the induced fit theory are two theories that explain enzyme specificity. The lock and key theory proposes that the enzyme's active site is already in the correct shape to bind the substrate, like a key fitting into a lock. The induced fit theory suggests that the active site of the enzyme can change its shape slightly to accommodate the substrate, similar to a glove molding around a hand.
What is a induced fit hypothesis?
a. The substrate can be altered so it is induced to fit into the enzyme's active site. b. The enzyme changes its shape slightly as it binds to the substrate. c. The enzyme is altered so it is induced to fit many different types of substrate. d. Several sites on an enzyme can be induced to act on a substrate.
As an enzyme fits into a substrate at the active site it undergoes a slight change in order to fit into the substrate. this process is defined by a concept called?
This process is defined by a concept called induced fit. Induced fit is the dynamic process where the enzyme structure adjusts slightly to better accommodate and bind to the substrate molecule.
How the lock and key model and the induced fit model differ?
According to lock and key model both the enzymes and the substrate possess specific geometrical shapes that fit exactly into one another. WHILE According to the induced fit model enzymes are more flexible structures and their active site is reshaped as substrate interacts with the enzymes.
How are the ''lock and key'' and ''induced fit'' models similar?
bontot
What are the limitations of the lock and key theory?
The lock and key theory of enzyme-substrate binding does not account for the induced fit model, where the enzyme and substrate can undergo conformational changes to better fit each other. It also does not explain the binding of substrates that are larger than the active site or the ability of enzymes to catalyze multiple types of reactions.
What is another name for line of best fit?
linear regression
Which statement describes the currently accepted theory of how an enzyme and its substrate fit together?
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
