3
What would happen if structure #2 were removed from the cell?
cell wouldn't be able to package proteins
cell wouldn't be able to store water
cell wouldn't be able to make energy
cell wouldn't be able to make proteins
4
Which best explains why energy is needed for active transport?
ions are attached to proteins
ions are moved against the concentration gradient
ions are trapped inside the cell membrane
Ions are negatively charged
5
Cells containing cyanide (limits ability to make ATP) is least likely to carry on which process
diffusion
osmosis
active transport
passive transport
6
What is the primary function of Nucleic Acids?
Long- term energy storage
Insulation
Store genetic information
Short term energy
7
What are the components of a DNA nucleotide?
glycerol + 3 fatty acid chains
Deoxyribose and ribose
Pentose Sugar
deoxyribose, nitrogen base, phosphate group
8
Cancer cells are different because they-
die after completing mitosis
fail to complete S phase
repeat the cell cycle continuously
mutate during G1
9
What are the differences between a plant cell and an animal cell?
Vacuole
All of the above
Chloroplasts
Cell wall
10
Which is a type of passive transport?
Exocytosis
Protein pumps
Endocytosis
Diffusion
11
What cell process is shown?
gene expression
photosynthesis
mitosis
DNA replication
12
What is the relationship between an organism's DNA and the proteins made in a cell?
DNA determines which RNA molecules are in proteins
DNA becomes a specific part of the protein
DNA determines the amino acid sequence of each protein
DNA determines the ribosomal RNA sequence
13

This is a poor hypothesis because-
not testable
observable
a comparison
a question
16
ENERGY must be released from food. Which structure serves that purpose?
structure 2
structure 3
structure 4
structure 1
17
Why does DNA replication need to happen during the interphase portion of the cell cycle?
cell needs 2 complete sets of DNA before it divides
the cell needs to repair after UV exposure
proteins need to be made for future cell structures
RNA transcription needs to take place
18
