Why are denatured enzymes not able to break down their substrates?
Denatured enzymes have lost their specific three-dimensional shape, which is essential for binding to their substrates. Without the correct shape, the enzyme cannot properly interact with the substrate to facilitate the necessary chemical reactions for breaking it down. As a result, denatured enzymes are unable to effectively catalyze the breakdown of their substrates.
Do One enzymes can be used for many different types of chemical reactions is this true or false?
True. Some enzymes are able to catalyze multiple types of chemical reactions due to their flexible active sites that can accommodate different substrates. This versatility allows them to participate in various metabolic pathways within an organism.
Is potato peroxidase destroyed by boiling?
Yes, boiling can denature peroxidase enzymes and potentially destroy their activity. High temperatures can break the hydrogen bonds holding the protein structure together, leading to a loss of enzyme function.
Do enzymes change shape to move substances across the plasma membrane?
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.
Which cell organelle is able to carry digestive enzymes to the vacuoles?
They are the lysosmes.They contain digestive enzymes

Why do enzymes only work with the specific substrates?
Enzymes act only on a specific substrate due to the active site of the enzymes fits perfectly with the substrate. Like 2 puzzle pieces, they can only go together and not with anything else. Enzymes catalyze or help a reaction take place. They bind substrates and then help position them in order that the chemical reaction between these substrates can take place. If they bound things other than the substrates they would be much less efficient in catalyzing the reactions.

How is a specific enzyme able to catalyze a specific reaction in the cytoplasm of a single cell with many different enzymes?
Enzymes have specific active sites that bind to specific substrate molecules, allowing them to catalyze specific reactions. Each enzyme has a unique shape that fits specific substrates like a lock and key. This specificity enables the enzyme to function in the cytoplasm of a cell with many other enzymes.
What would happen if you mixed peroxide and enzyme?
Mixing peroxide with enzymes can potentially increase the rate of chemical reactions. Peroxide can act as a catalyst to break down substrates that the enzyme may normally not be able to react with efficiently. However, the specific outcome would depend on the type of enzyme and peroxide being used.

How subtstrates and enzymes fit together?
There are basically two theories to suggest how enzymes and substrates fit together. They are: The lock and key mechanism - this says that the structure of the substrate is exactly complimentary to the structure of the active site (i.e the region on the enzyme where the substrate fits/docks). The process is explained in terms of a lock and key analogy. The induced fit mechanism - this says that the active site of the enzyme is able to change its confirmatin (i.e 3D structure) slightly in order to accomodate the substrate.
Why is the catalytic activity of enzymes essential to ensure and regulate cellular metabolism?
Enzymes lower the activation energy for chemical reactions, allowing the reactions to proceed. Enzymes also can serve to bring components of a reaction together in the proper orientation. Enzymes can hydrolyze macromolecules into smaller components, enabling them to be transported across the cell membrane. Without enzymes, many metabolic reactions would not be able to be conducted efficiently, if at all.

Without enzymes are molecules able to bond with each other and why?
Yes - without enzymes molecules can still bind together - but the process will usually take much longer. Enzymes are catalysts - which means that they lower the activation energy for reactions. This means that reactions occur more quickly. However, enzymes cannot make reactions occur which would not (eventually) occur without the enzyme present.
