1. Construct Make a table to record information about the four main organic
molecules that make life possible. The table column headings should be
"Molecule," "Description," and "How Used by Living Things."
The four major classes of biomolecules are carbohydrates, lipids, proteins and nucleic acids. These biomolecules are fundamental for the functioning of all biological systems.
Molecule: carbohydratesDescription: complex carbohydrates are polymers composed of many subunits called monosaccharides (i.e., simple carbohydrates) linked by glycosidic bonds.How Used by Living Things: structural and energy roles. Complex carbohydrates provide a more lasting energy source in the body than simple carbohydrates.Molecule: lipidsDescription: lipids are a broad category of biomolecules that may be composed of one or more fatty acid chains and a glycerol backbone. How Used by Living Things: lipids provide a source of long-term energy for cells, heat insulation, structural roles in the cell membrane (phospholipids and cholesterol, etc).Molecule: proteinsDescription: proteins are polymers composed of a linear chain of amino acids linked by peptide bonds.How Used by Living Things: proteins have structural (e.g., actin filaments) and enzymatic (e.g., catalase) functions.Molecule: nucleic acidsDescription: nucleic acids (DNA and RNA) are polymers consisting of long chains of nucleotides.How Used by Living Things: DNA contains the hereditary information which is required to synthesize any protein. RNA serves as a transition molecule that helps to regulate the type and amount of proteins in cells.Learn more in:

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 answer option which correctly orders events during mitosis is: D. The mitotic spindle attaches to chromosomes. Microtubules organize the chromosomes. The nuclear membrane dissolves.
Mitosis can be defined as a type of cell division (duplication) through which a single or one (1) parent cell produces two (2) genetically identical daughter cells.
In Biology, duplication division refers to a process in which two (2) genetically identical daughter cells produced by one (1) parent cell have the same number of chromosomes as their parent cell.
Furthermore, the correct order (sequence) of events during mitotic division in living organisms include the following:
1. The mitotic spindle (spindle fibers) of microtubules attaches to chromosomes.
2. The chromosomes found in a sex cell are organized by microtubules.

Recently there has been a decline in the abundance of life on coral reefs. Scientists are unsure why, but one of the explanations for it is that global temperatures are increasing, making water temperatures rise. These small changes are killing off some of the smallest animals on the reef, which then affects the entire food chain. Which of the following would NOT help protect the diversity of the coral reef?
a: creating coral reefs in cooler waters ?
b: limit fishing around reefs
c : ban places of anchors in reef
d: ban cities into discarding sewage into coral reefs
Limit fishing around reefs would not help to protect the diversity of coral reefs.
What are coral reefs?Coral reefs are among the world's most diversified ecosystem and an underwater habitat that is characterized by corals that construct reefs.
Coral polyps, the invertebrates responsible for reef formation, come in a variety of shapes and sizes, including vast reef-building colonies, graceful flowing fans, and even small, solitary species.
Coral polyp colonies are bound together by calcium carbonate to build reefs.
According to UNESCO, if we continue to generate greenhouse gases at current levels, the coral reefs in all 29 reef-containing World Heritage sites would be extinct by the end of this century.
The Paris Agreement's goal of keeping global average temperature far below 2°C above pre-industrial levels is the only way for coral reefs to survive.
