Exam 1 Jeopardy questions Flashcards
This macromolecule consists of long chains of amino acids
protein
A nitrogenous base, a phosphate group, and a pentose sugar are the three components of this type of macromolecule.
nucleic acids
This class of macromolecules does not produce polymers
lipids
Glyceraldehyde, Ribose, and Galactose are all examples of these.
monosaccharides
This macromolecule functions to store amino acids, protect against disease, transport substances, and speed up chemical reactions.
protein
This type of bond forms between the atoms of a water molecule.
covalent bond
When an electron is transferred from a sodium atom to a chlorine atom, the sodium becomes this type of ion.
cation
If Nitrogen has 5 valence electrons, how many bonds can it form?
three
This type of covalent bond results from equal sharing of electrons.
non-polar covalent bond
This type of bond links monosaccharides together to form disaccharides.
glycosidic linkage
Energy flows into an ecosystem as this and leaves as this.
light and heat
This level of biological organization consists of all the individuals of a single species in a particular area.
population
This level of biological taxonomy includes the classifications: Bacteria, Eukarya, and Archaea.
domain
These are broad in scope and supported by a large body of evidence.
scientific theories
This is the basis of all reproduction, growth, and repair in multicellular organisms, but only reproduction in unicellular organisms.
cell division
Solutions with a pH greater than 7 are referred to as this.
basic or alkaline
A high hydrogen ion (H+) concentration makes a substance this.
acidic
These substances are attracted to water and have polar bonds.
hydrophilic substances
The process of a hydrogen bond holding two water molecules together is called ________.
cohesion
These substances can minimize changes in concentrations of H+ and OH- in a solution.
buffers
This functional group forms alcohols.
hydroxyl or OH group
The molecular formula for this functional group is –COOH.
carboxyl group
How many phosphate groups are found in a single molecule of ATP?
three
The Carbonyl group is located at the end of the carbon chain on this type of sugar molecule.
aldehyde (aldose) sugar
When added to a protein, this functional group stabilizes and changes the shape of the protein by forming disulfide bonds.
sulfhydryl gorup
In On the Origin of Species, Darwin wrote that this explains the unity and diversity of life.
evolution
