Exploring Life
What is the role of dehydration synthesis?
What is to link monomers together to form polymers.
A scientist conducted an experiment to find out what type of macromolecule a virus injects into a cell. Using radiolabeled atoms, the scientist found that phosphorus and nitrogen from the virus enters the cell but sulfur did not. What macromolecule would most likely be injected?
Nucleic Acid
What elements are present is a protein?
C,H,O,N, Sometimes S.
Which macromolecule is the hereditary material in living things.
What is Nucleic Acids (polymers): DNA and RNA
Which type of lipid has a double bond in its hydrocarbon chain?
Unsaturated Fatty Acids
What are the two functional groups found on an amino acid?
What is a amino (NH2) and a carboxyl (COOH).
Lipids are made up of these monomers.
What is Fatty Acids
These types of macromolecules can be used as short term sources of energy or used for structural support:
What is Carbohydrates?
Proteins are made of amino acids that have three types of R groups. Name these types of R groups
What is polar or hydrophilic, nonpolar or hydrophobic, and charged
Which of the following is responsible for the cohesive property of water? Covalent Bond or Hydrogen Bond?
Hydrogen bonds between the oxygen atom of one water molecule and a hydrogen atom of another water molecule
Which level of a proteins structure would contain alpha helixes and beta sheets due to hydrogen bonding between adjacent amino acids?
What is Secondary Structure?
A reaction that breaks polymers.
What is hydrolysis.
What is a protein?
Which macromolecules contain the same elements, but in different ratios?
Carbs and Lipids
Water is often referred to as a polar molecule, what does this mean?
What is that water is a molecule in which the electrons are UNEQUALLY spread out or shared amongst the atoms. This distribution causes partial charges on the molecule that give water its unique properties.
Proteins only sometimes form this level of organization because it requires multiple polypeptides.
What is 4th or quaternary structure?
Covid 19 is a single stranded RNA virus. Which nitrogenous bases would likely be found in this polymer?
Adenine, Uracil, Guanine, Cytosine
Which macromolecule has a monomer that is made of 3 parts? What is the name of this monomer?
What is a nucleic Acid? 1) Sugar 2) Phosphate 3) Nitrogenous Base
Plants in arid climates often need to conserves water loss due to evaporation through the leaves of the plant. Some plant species have a waxy , nonpolar cuticle on the outer surface of thier leaves.
A student claims that this waxy cuticle reduces water loss from the leaves. Support the studetns claim with reasoning.
Polar water molecules cannot cross a waxy, nonpolar layer, so less water can evaporate from leaves surrounding by a way hydrophobic cuticle.
Describe how a protein would fold if dropped in a solutions of water using the words amino acids, hydrophobic and hydrophilic.
What is that protein would fold such that hydrophilic amino acids are on the outside of the protein , while hydrophobic amino acids are on the interoir.
