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

1) Why does the addition of dideoxynucleotides to the DNA sequencing reaction cause DNA synthesis to stop after the modified nucleotide is added?
A)Because once a modified nucleotide is incorporated into the DNA, there is no free 5'OH group to attach the next nucleotide being added.
B)Because once a modified nucleotide is incorporated into the DNA, there is no free 3'PO4-group to attach the next nucleotide being added.
C)Because once a modified nucleotide is incorporated into the DNA, there is no free 3'OH group to attach the next nucleotide being added.
D)Because once a modified nucleotide is incorporated into the DNA, there is no free 5'PO4-group to attach the next nucleotide being added.
In Sanger sequencing, once a modified nucleotide is incorporated into the DNA, there is no free 3'OH group to attach the next nucleotide being added. This phenomenon is useful to sequence a polynucleotide chain.
Dideoxynucleotides (ddNTPs) are nucleotide inhibitors of the DNA polymerase, it is for that reason that they are used in Sanger sequencing.
The ddNTPs are similar to natural deoxynucleotides used by cells during ADN replication; however, ddNTPs lack a hydroxyl (OH) group on the 3’ carbon of the deoxyribose.
In consequence, once a ddNTP is added, DNA synthesis cannot progress, thereby this phenomenon can be used to determine the order of nucleotides during the elongation of a polynucleotide DNA chain.

1. A rock sample has a mass of 16 grams:
and a volume of 8 cubic centimeters.
When the rock is cut in half, what is
the volume and density of each piece?
(1) 8 cm3 and 0.5 g/cm3
(2) 8 cm² and 1.0 g/cm3
(3) 4 cm' and 2.0 g/cm3
(4) 4 cm3 and 4.0 g/cm3
1
Answer:
(3) 4 cm' and 2.0 g/cm3
Explanation:
Given:
volume= V= 8 cm³
mass= m= 16 g
The density is the mass per volume of a substance, so the density of the rock is:
density= d= 16 g/8 cm³= 2 g/cm³
When we cut the rock in half, we have a half volume and a half mass:
V= 8 cm³/2= 4 cm³
m= 16 g/2= 8 g
But the density is not altered because it is an intrisic property - it does not change with the amount of subtance. Thus, the density of a half rock is:
d = m/V= 8 g/4 cm³= 2 g/cm³

Answer:
At land
Explanation:
Carbon is a raw material for photosynthesis, in the form of carbon dioxide. Green plants use it to make vital organic compounds. On the land, plants get the carbon they need as a gas from the air. In water, plants ranging from seaweeds to phytoplankton are supplied by dissolved carbon dioxide, CO2.
Which term can avoid traveling through a solid, a liquid, or a gas?
The term that can avoid traveling through a solid, a liquid, or a gas is "electromagnetic radiation" or "light."
Electromagnetic radiation: Electromagnetic radiation refers to the propagation of energy in the form of waves or particles through space. It includes various types of radiation, such as visible light, radio waves, microwaves, X-rays, and gamma rays.Traveling through solids: Solids have a tightly packed arrangement of atoms or molecules, which makes it difficult for electromagnetic radiation to pass through them. The particles in solids interact with the radiation and absorb or scatter it, preventing its transmission.Traveling through liquids: Liquids have a less rigid arrangement of particles compared to solids. While some electromagnetic radiation can pass through liquids, it may be partially absorbed or scattered due to interactions with the liquid molecules.Traveling through gases: Gases have widely spaced particles, allowing electromagnetic radiation to travel more freely compared to solids and liquids. However, certain gases can still interact with specific types of radiation, such as absorbing certain wavelengths or causing scattering.Overall, electromagnetic radiation, or light, has the unique property of being able to propagate through a vacuum, which means it can travel through space where there is no matter present, as well as through various mediums, including gases, liquids, and solids.
