Section 1

Question Answer
What are the differences between prokaryotic and eukaryotic cells?pro has no nucleus; DNA is much smaller in Eukaryotic
What is the equation for photosynthesis?6CO2 + 6H2O —> C6H12O6 + 6O2
Where does photosynthesis occur?plant chloroplasts
What is the equation for cellular respiration?C6H12O6+6O2---->6CO2+6H2O+ ATP energy
Where does cellular respiration occur?mitochondria
How does carbon enter the atmosphere from the biosphere?cellular respiration

Section 2

Question Answer
what is the reactant of photosynthesis carbon dioxide, water
what is the product of photosynthesisglucose, oxygen
What is the reactant of cellular respiration?glucose, oxygen
what energy is involved in photosynthesisinput of radiant energy
what is the product of cellular respiration?carbon dioxide, water
what energy is involved in cellular respiration?releases of ATP (chemical energy)
What is the conversion of light energy to chemical energy?photosynthesis
What is the conversion of stored energy to usable energy?Cellular Respiration
Where does photosynthesis occur?chloroplasts
Where does Cellular respiration occur?Mitochondria

Section 3

Question Answer
Define passive transportdoes not require energy
what are the three types of passive transportosmosis, diffusion, facilitated diffusion
Define active transportrequires energy
What determines an organisms traits?sequence
what are the two steps of protein synthesis and where does each step occur?transcription/translation
where does transcription occur?nucleus
what does transcription mean?to copy
define translationconverting the codons on mRNA into a sequence of amino acids to make a protein
where does translation take place?ribosomes
purpose of translation?mRNA brings the codons (message) from DNA to the ribosome (rRNA)
How many amino acids does tRNA bring?one
Anticodonthree nucleotides on the bottom of the rRNA
what is the first codon on an mRNA that is brought to a ribosome?AUG
Once the correct tRNA binds to the first codon, what happens?UAC comes and binds with this codon and drops off methonine
what is the end result of translation?proteins

Section 4

Question Answer
isotonic solutionsolvent does the dissolving and solute is dissolved ; iso=same
hypertonic solutionmore solution outside and it will leave the cell trying to make the ratio the same; shrink/shrivel
hypotonic solutiontoo much salt not enough water and water goes in cell and swells up like a balloon; cell dies
which way does active transport goagainst the concentration gradient
what are different types of active transportion pumps, endocytosis, exocytosis

Section 5

Question Answer
stem cellcell without function; able to develop into a variety of different cell types
cells differentiation the process by which an immature cell becomes specialized to perform a specific function
what determines cellular differentiationchemical signals

Section 6

Question Answer
ribosomeorganelles without membranes that use directions from DNA to make proteins
mitochondriontransforms food energy to chemical energy, performs all functions, cellular respiration
chloroplast makes glucose
nucleusstores genetic information
cell wallrigid structure for protection in animal cells only
cell membraneprotective skin ion all cells, maintains internal balance by controlling what goes in and out of the cell
