Water Properties
This element in a water molecule has a greater pull on electrons making it partially negative
What is Oxygen?
This is the portion of an amino acid that gives it its unique qualities.
What is an R-Group?
This process is used to cleave covalent bonds between monomers.
What is hydrolysis?
This nucleotide is present in RNA but not in DNA.
What is Uracil?
The exchange of materials between cells and the environment is affected by this ratio.
What is Surface Area:Volume Ratio
This property of water allows it to dissolve many substances.
What is Polarity?
These types of amino acids will situate themselves towards the outside of a tertiary protein?
This process is used to form covalent bonds between monomers.
What is Dehydration Synthesis?
These macromolecules comprise sugar monomers whose structures determine their properties and functions.
What are carbohydrates?
Specialized structures and strategies are used for this purpose in the efficient exchange of molecules.
What is to increase surface area?
The ability of water molecules to stick to each other relies on these bonds?
What are hydrogen bonds?
These are found at either end of a polypeptide chain?
What are the N and C terminus? (amino and carboxyl)
The order of these determines the overall shape of a protein.
What are amino acids?
This element is used to build proteins and nucleic acids and no other macromolecule.
What is Nitrogen
Give one example of a specialized structure used for efficient exchange of molecules.
What are fingerlike projections?
What are "dips" in the cell?
What are long extensions?
The crystalline lattice of ice causes it to be denser than liquid water. True or False
What is FALSE?
Mrs. Baker will give you the question
Which statement best explains why correct protein folding is critical in the transmembrane protein shown above?
A. Interactions of the hydrophobic and hydrophilic amino acids help to anchor the protein in the membrane.
Double Carbon Bonds found in lipids allows for those molecules to be solid at room temperature. True or False
This represents the opposite directionality in which a DNA molecule is structured.
What is antiparallel?
The efficiency of material exchange is increases as the surface area-to-volume ratio increases, true or false?
What is TRUE?
Mrs. Baker has to give you the question sheet!!
Water and ammonia interact to form hydrogen bonds, as represented in the figure.
Which statement best helps explain the formation of the hydrogen bond represented in the figure?
B. The nitrogen has a partial negative charge, and the hydrogen attached to the oxygen has a partial positive charge.
Mrs. Baker Will give you th FRQ
The stems and fruits of pineapple plants contain a group of protein-digesting enzymes collectively called bromelain and often used as an antibrowning agent for fruits and vegetables. Fruits and vegetables brown when they are bruised during transport or sliced and exposed to air. This browning is controlled by enzymatic pathways that produce brown pigments. The browning of fruits and vegetables reduces the nutritional value of the food, so antibrowning agents such as bromelain are used.
The response indicates that amino acids are the monomers of which this enzyme is composed.
The response indicates that bromelain acts by enabling the hydrolysis of the protein/polypeptide/amino acid chain, breaking apart the peptide bonds holding the amino acids together OR that bromelain breaks the bond between amino acids by using water as a reactant.
Mrs. Baker will give you the question
The observed differences between the groups most likely resulted from differences in the ability of the seedlings to produce which of the following monomers?
C
Mrs. Baker will give you the question
Which of the following statements best explains the data set?
B. Since the %A and the %T are approximately the same in each sample, adenine and thymine molecules must pair up in a double-stranded DNA molecule.
Mrs. Baker will give you the question
Which of the following outcomes will most likely result from a change in the shape of the mitochondrial inner membrane from a highly folded surface to a smooth, flat surface?
D. Mitochondria will become less efficient because the surface area of the inner mitochondrial membranes will decrease.
