What are the deep folds in an enzyme called?
Active sites.
Where an enzyme and substance meet or connect?
Membrane Proteins, or transport site, these sites act as transporters, enzymes, cell surface receptors and cell surface identity markers, as well as aiding in cell-to-cell adhesion and securing the cytoskeleton.
Parts of the enzyme molecule that interact with a substrate are called?
active sites
Does the allosteric effect in an enzyme change the enzyme's function?
allosteric effectors have their own specific sites for binding to enzyme. they can bring positiveor negative effect. that depends on the natre of effector.
Why did you cut both segments of DNA with the same restriction enzyme?
You use the same enzyme inn order to get the same restriction and binding sites.
Why must a molecule have a specific shape if it is to be a substrate of an enzyme?
Active sites of enzymes (where the substrates fit in) are substrate specific, and are complementary to the shape of the molecule (substrate). In this way, enzymes can only act on a specific substrate, since that is the only shape that it will accommodate in the active site.
Molecule that binds to an enzyme?
a substrate =================================== or an "interacting molecule".
How does temperature affects activity?
The enzyme activity increases as the temperature rises due to the substrates colliding with the enzymes' active sites more frequently at higher temperatures. However, each enzyme has an optimum temperature as high temperatures denature enzymes.
Do substrates get consumed in enzyme reactions?
On active sites of enzymes, substrates bind to form products.Specific activity is usually expressed as μmol of substrate transformed to product per minute per milligram of enzyme under optimal conditions of measurement.The rate of a reaction is the concentration of substrate disappearing (or product produced) per unit time (mol-1 L-1 s-1 ).
What is the similarities between enzyme and hormone?
Both enzymes and receptors have specific sites for the substrates to bind. The receptor causes a response beyond the cell membrane and the enzyme facilitates a chemical change in the substrate. Enzymes can be membrane bound or free floating. Receptors are usually membrane proteins
What are 4 ways enzymes can lower activation energy?
1. orienting(direction) substrates correctly 2. straining substrate bonds 3. Providing a favorable micro environment 4. Covalently bonding to the substrate got the answers from my AP Bio notes....

Why would a factor that changes the shape of an enzyme prevent it from functioning?
Enzymes are biologically active molecules with specific "active sites", a good analogy is a key and its characteristic notches. If the factor modifies the enzyme's shape then the locations of the enzyme's "active sites" (notches, so to speak) may also be changed, or the sites may be deleteriously affected. Thus the functionality of the enzyme is impaired.
How many natural world heritage sites are there?
There are 206 natural World Heritage sites.
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.
Parts of the enzyme molecule that interact with a substrate are called?
active sites
