Molecules and cells have reaction and activity areas known under three terms. These are active, receptor, and binding sites. Such sites have markers and binding proteins allowing for their activation and or transfer of genetic materials.

Large molecules may have reaction sites termed -----because they are attracted to water?

Why does the enzyme act as catalyst?
A) The enzyme does not actively take part in the reaction. It just indicates that the reaction is complete. B) Enzymes react with the substrate molecules to form products and become denatured in the process. C) Enzymes ensure that the reaction continues without inhibition even if conditions such as temperature and pH are changed. D) The products of the reaction are released from the active sites of the enzyme, allowing other substrate molecules to bind with the sites.

How does an enzymes interact with a substrate?
Substrate molecules bind to enzymes at specific active sites thus activating the enzyme. The enzyme then reduces the activation energy required for a bond to form between the substrate molecules, so bonding (the reaction) proceeds at a faster rate.
Do restriction enzymes cut protein molecules at specific sites?
No. restriction enzymes do not cut proteins. restriction enzymes cut DNA molecules at specific sites called restriction sites.
What type of molecules need more help to get through the membrane and What is help them?
Large or polar molecules typically need more help to get through the membrane. They rely on specialized transport proteins such as channels or carriers to facilitate their passage. These transport proteins create pores or binding sites that allow the molecules to cross the membrane.
Why does the enzyme act as a catalyst?
That depends on weather it is combining or separating the two substances. If it combining the two, then the 2 substances will both attach to the enzyme's active site (where the combination/separation occurs), where the enzyme will then just squeeze the 2 substances together. If it is separating the two, the the substances will again attach to the active site, but the enzyme will then contort itself so that the items will be separated by simple force. You may also want to note the an enzyme is NEVER used up after reactions. Individual enzymes undergo many reactions.
Does Tropomyosin molecules move and expose specific sites on myosin filaments?
true
What are enzymes and what are their function?
Enzymes are biological catalysts that increase the rate of a biological reaction. They have several properties to carry out their functions as catalysts: firstly they have active sites that induce bond-bending and stretching so as to reduce the activation energy required for the reaction to occur. They also can provide an optimal environment for the reaction to take place, i.e. a low pH environment.
What blocks the binding sites on actin?
TROPOMYOSIN MOLECULES ( troponin hold the tropomyosin in place)
Binding sites on the actin molecules are covered by troponin and?
muscle that produces a give movement
What web sites sell large quantities and a good variety of wine online?
You can purchase large quantities of wine online thru www.wine.com and www.winecellar.com. These sites have reasonable prices and ship in large quanties.
