How Enzymes Function Enzymes are biological catalysts. They can increase the rate of chemical reactions as much as a millionfold by lowering the energy barrier of a reaction.
Part A - Enzymes and activation energy The graph presents three activation energy profiles for a chemical reaction (the hydrolysis of sucrose): an uncatalyzed reaction, and the same reaction catalyzed by two different enzymes. Rank these by reaction rate, as measured by the rate of product formation (from the most product formed to the least product formed). To rank items as equivalent, overlap them.
Part B - Factors that affect enzymes Complete this vocabulary exercise relating to enzymes. Match the words in the left-hand column to the appropriate blank in the sentences in the right-hand column. HelpReset cofactor specific denatured substrate active site catalyst complex
1. An enzyme is when it loses its native conformation and its biological activity.
2. An enzyme is considered a because it speeds up chemical reactions without being used up.
3. An enzyme is considered because of its ability to recognize the shape of a particular molecule.
4. A , such as a vitamin, binds to an enzyme and plays a role in catalysis.
5. When properly aligned, the enzyme and substrate form an enzyme-substrate (ES) .
6. A substrate binds to an enzyme at the , where the reaction occurs.
7. In a catalyzed reaction a reactant is often called a _________.

Answer:1. An enzyme is denatured when it looses its native conformation and its biological activity. Enzyme is a protein and at high temperatures, the shape of the proteins is altered, preventing it from its function. In addition change in pH above optimal may also cause denaturation of enzymes inactive.  

2. An enzyme is considered a catalyst because it speeds up chemical reaction without being used up. A catalyst is a substance that speeds up chemical reactions by reducing the activation energy of the reactants, they are not consumed during the reactions. Enzyme are biochemical catalysts that speeds up chemical enzymatic reactions without being consumed just like normal catalysts.

3. An enzyme is considered specific because of its ability to recognize  the shape of a particular molecule. One property of enzyme is that they are substrate specific and will act on specific substrate, others will act on a specific type of chemical bond or functional group, while others will catalyze only one reaction (absolute specificity)

4. A cofactor such as a vitamin, binds to an enzyme and plays a role in catalysis. Cofactors are mostly metal ions (such as Zn ions or iron ions) or coenzymes are inorganic and organic chemical that aid the activity of enzymes. Coenzymes are non protein molecules mostly vitamins or vitamins derivatives that enhance enzyme activity.

5. When properly aligned, the enzyme and substrate form an enzyme-substrate (ES) complex. Es complex is the intermediate formed when a substrate molecule interacts with the active sites of an enzyme. After the formation of the complex then the substrate undergoes a chemical reaction and is converted to product.

6. A substrate binds to an enzyme at the active-site, where the reactions occurs. Active sites is a region on the enzyme where substrate molecules bind and undergoes a chemical reaction where it is converted to product. These sites contain the binding site and the catalytic site.

7. In catalyzed reaction, a reactant is often called a substrate. Substrate molecule is the substance that is acted upon by an enzyme and is converted to a product. The substrate forms an interaction with the binding site of the active site then the catalytic site of the active site converts the substrate to a product during catalysis.

1. Denatured

2. Catalyst

3. Specific

4. Cofactor

5. Complex

6. Active Site

7. Substrate

The induced fit model states an substrate binds to an active site and both change shape slightly, creating an ideal fit for catalysis. When an enzyme binds its substrate it forms an enzyme-substrate complex. ... The enzyme will always return to its original state at the completion of the reaction.

"The active site of the enzyme has a complementary rigid structure" belongs to the key and lock system

Q6.2. There are many diseases that do not infect a person more than once, such as chicken pox
and measles. What is responsible for this lifetime immunity?

The innate immune response, because barriers to entering the body improve with age.

The innate immune response, because adults have more white blood cells than children.

The acquired immune response, because antibodies are developed from previous infections.

The acquired immune response, because it responds rapidly to broad classes of pathogens.

which of the following summarizes the endocrine system's role?
- to carry nerve impulses throughout the body in order to maintain homeostasis
- to receive information about what is happening inside and outside of the body
- to regulate body activities (like growth and immunity) by sending chemical messages

Consider the global 'Greenhouse Effect", where thermal energy from the sun is naturally trapped by 'greenhouse gases' present within the Earth's atmosphere. A majority of heat generated from this process is then absorbed by the world's oceans, where it is sequestered and stored. What are some of the predictable consequences recently observed over the past 40-50 years with the observed rise in Global Mean Temperature, correlate with an increase in greenhouse gas emissions from burning of fossil fuels across that same period?
a. retreat of winter and summer sea ice, decreasing the amount of solar energy directly absorbed into the oceans
b. warming of deep ocean water and increased evaporation at the surface
c. warming of oceanic surface temperatures, driving the formation of more powerful hurricanes & rainstorms
d. thermal expansion of oceanic water, leading to mean global sea level rise
e. melting of Himalayan glaciers and collapse of Antarctic ice shelves into the sea
