Cell Transport
What type of transport requires energy in the form of ATP?
Active Transport
Answers will vary
What does ATP stand for?
Adenosine Triphosphate
What are the monomers for nucleic acids?
What are homologous structures?
Structures that show a common ancestry
When molecules follow the "concentration gradient" what does this mean?
Molecules will move from a high concentration to a low concentration
Name two types of eukaryotic cells
Plant, animal, and or fungal
How does the ATP-ADP Cycle work?
When energy is used, a phosphate detaches and ATP becomes ADP. When energy is absorbed, ADP becomes ATP as a phosphate group is reattached to ADP.
DNA: Double stranded and contains the bases A,T,C, & G.
RNA: Single stranded and contains the bases A,U, C, & G.
Animals with analogous structures -- meaning they look similar but are NOT related (i.e. fish and dolphins)
What is the difference between facilitated diffusion and diffusion?
Facilitated utlizes protein channels to move molecules across the membrane, while simple diffusion does not.
BOTH move molecules from HIGH to LOW
What are the three differences between animal and plant cells (i.e. organelles)
Plant cells have a:
-chloroplast
- cell wall
- central vacuole
What is the chemical equation for cellular respiration and photosynthesis?
Cell Resp: oxygen + sugar -> carbon dioxide + water
Photosynthesis: carbon dioxide + water -> oxygen + sugar
Phosphate, Sugar (either deoxyribose or ribose) and a nitrogenous base
Name two types of speciation/isolation and describe them
Geographical - separated by mountains or rivers
Behavioral- different mating rituals
Temporal - different mating seasons
Reproductive - the sec cells are incompatible
Maintaining stable internal conditions (on a cellular level, it means to maintain equillibrium).
Humans can shiver and sweat to maintain homeostasis
Name three organelles and their functions
Answers will vary
Where does the light independent and light dependent reactions occur?
Independent: stroma
Dependent: thylakoid membrane
What is the difference between homozygous and heterozygous with regards to heritable traits?
Homozygous = two of the same alleles for a trait (AA or aa)
Heterozygous = two different alleles for a trait (Aa)
What is coevolution?
When two species evolve in response to one another
Define Hypotonic, Hypertonic, and Isotonic
Hypo = water moves into the cell
Hyper = water moves out of the cell
Iso = no net movement of water
What is photosynthesis and which organelle is responsible for this process?
Photosynthesis is the process by which sunlight is converted into chemical energy (or sugar); this process takes place in the chloroplast
What are the steps of cellular respiration?
1. Glycolysis
2. Kreb's Cycle
3. ETC
Transcribe the DNA strand into mRNA
ATG - CCC - GAT - ACC
UAC - GGG - CUA - UGG
Define producers and consumers. Name and describe two types of consumers
Producer: uses sun's energy to make food
Consumer: All creatures that must eat other creatures to survive.
Consumers: carnivores, herbivores, omnivores, detritivores
