Water in the Wild
Water molecules sticking to other water molecules demonstrate this property.
What is cohesion?
These five elements are the most prevalent elements used to build biological macromolecules.
What are carbon, hydrogen, nitrogen, oxygen, and phosphorous?
Glycogen, starch, and cellulose are all examples of this class of macromolecule.
What are carbohydrates?
The exact order of amino acids in a polypeptide defines this level of protein structure.
What is primary structure?
This type of bond holds a single water molecule together.
What is a covalent bond?
Water molecules sticking to a polar surface demonstrate this different property.
What is adhesion?
A shortage of this element would directly interfere with the production of nucleic acids and proteins.
What is nitrogen?
Fats, steroids, cholesterol, and phospholipids all belong to this broad molecular category.
What are lipids?
Interactions among R groups are especially important in forming this three-dimensional level of protein structure.
What is tertiary structure?
An RNA nucleotide differs from a DNA nucleotide because it has this unique nitrogenous base.
What is uracil?
What is vaporization (or evaporation)?
A cell is unable to obtain enough phosphorus from its environment. The production of these two types of biological molecules would be directly affected.
What are nucleic acids and phospholipids?
Unlike many other macromolecules, these macromolecules are typically nonpolar and hydrophobic.
What are lipids?
When several polypeptide chains interact to make one functional protein, the protein exhibits this level of structure.
What is quaternary structure?
High temperature disrupts the interactions maintaining a protein’s three-dimensional shape without breaking its peptide bonds. This process can cause the protein to lose its function.
What is denaturation?
During sweating, the water molecules most likely to escape first are those possessing relatively large amounts of this.
What is kinetic energy (or heat)?
A researcher finds a biological molecule containing carbon, hydrogen, oxygen, nitrogen, and sulfur. Based on its elemental composition, this molecule is most likely a member of this macromolecule group.
What are proteins?
A cell links 15 monomers together to form a single polymer. Assuming each new bond forms by dehydration synthesis, how many water molecules are produced?
What is 14 water molecules?
A substitution changes an R group from hydrophilic to hydrophobic. Why might the protein's shape change, even though its peptide backbone remains intact?
What is because of altered R group interactions changing folding structure?
Two fatty acids have equal chain lengths. Fatty acid X has three carbon-carbon double bonds and fatty acid Y has no carbon-carbon double bonds. At room temperature, which fatty acid is expected to be more liquid?
What is fatty acid X?
A coastal organism experiences much smaller daily temperature fluctuations than an organism living far inland, even though both regions receive similar amounts of solar energy. Which property of water helps explain this difference?
What is water's high specific heat capacity?
A molecule contains C, H, O, N, and P and consists of repeating units containing sugar, phosphate, and a nitrogenous base. Identify the macromolecule.
What are nucleic acids?
This molecule contributes structural stability (temperature regulation) to an animal cell membrane but is not a phospholipid.
What is cholesterol?
A mutation prevents hydrogen bonds from forming between the polypeptide backbone of a protein. These two structures of secondary protein structure would be affected.
What is alpha helix and beta pleated sheet?
A DNA molecule contains 30% adenine. Based on complementary base pairing, this percentage of the DNA must be cytosine.
