This element is present in all organic molecules.
What is carbon.
100
This is the hydrogen ion concentration of a solution with pH 8
What is 10^-8M
100
These are the monomers that make up DNA/RNA, proteins, and polysaccharides (3 separate answers)
What are nucleotides, amino acids, sugar monomers
100
This is the movement of a solution down its concentration gradient through a channel.
What is facilitated diffusion
100
This is necessary for the movement of dynein, kinesin and myosin
What is ATP
200
These two groups are always found amino acids
What is amino and carboxyl
200
The high specific heat of water is a consequence of the absorption and release of heat from the breaking and forming of these.
What is hydrogen bonds
200
A dimer must undergo this reaction to put together two monomers
What is dehydration synthesis
200
This is the kind of solution that causes a cell to lyse
What is hypotonic
200
These structures contain the 9+2 arrangement of microtubules.
What are motile cilia and flagella
300
These make hydrocarbons insoluble in water
What are nonpolar covalent bonds
300
A solution that prevents large fluctuations in pH
What is a buffer
300
A change in the primary structure of a protein could cause this
What are a change in tertiary structure and biological function
300
These structures allow water to pass through membranes easily
What is aquaporins
300
Hydrolytic enzymes are found in this organelle
What are lysosomes
400
How many electron pairs are shared between carbon atoms in a molecule that has the formula C2H4
What is 2
400
Water can form hydrogen bonds with compounds that have these bonds
What is polar covalent
400
The complementary sequence of 5'ATTGCA3' (indicate the 5' and 3' ends)
What is 3'TAACGT5'
400
This is the use of ATP to move across a membrane against its concentration gradient.
What is active transport
400
The presence of this organelle in liver cells aids in detoxification
What is smooth endoplasmic reticulum
500
If a salamander relied on hydrogen bonds to cling to surfaces, what type of surface would cause the most problems?
What is a non-polar surface, created by C and H atoms bound together covalently or lipophilic surface
500
The pH of a 1 milimolar NaOH solution
What is 11
500
A labeled uridine triphosphate would allow identification of this macromolecule.
What is RNA

What is amphipathic, at least one hydrophobic part
500
Cytosolic proteins are made by this (be specific)
What is free ribosomes
