q2 assessment Flashcards
(32 cards)
what is the original source of energy
the sun
what is the difference between a heterotroph and an autotroph
autotrophs make their own food and heterotrophs must consume other organisms for energy
what is the equation for photosynethesis
carbon dioxide+light+H20 yields Sugar + oxygen
in which organelle does photosynthesis occur in
the chloroplast
what are the two reactions in photosynthesis
the light reaction and the Calvin cycle
what is the equation for cellular respiration
sugar+oxygen yields light+H20+co2
what are the 3 reactions of aerobic respiration
glycolysis, kreb cycle, and electron transport cycle
where do the different cycles of cellular respiration occur
glycolysis-cytoplasm
kreb cycle- mitochondrial matrix
etc- mitochondrial membrane
which reaction of the aerobic respiration makes the most atp
etc
what is the purpose of anaerobic respiration
to produce energy without oxygen
what is the purpose of aerobic respiration
to produce energy with oxygen
what are the 2 types of aerobic respirations
lactic acid fermentation and alcoholic fermentation
What was Griffith’s Experimental design and conclusion
Heat-killed bacteria and that something gets passed on
What was Avery Experimental design and conclusion
Transformation and DNA is what gets passed on
What was Hershey-Chase Experimental design and conclusion
Radioactive bacteriophage and confirms avery
What was Chargaff Experimental design and conclusion
Compares species DNA and A=T C=G
What was Franklin Experimental design and conclusion
x-ray crystallography and DNA structure is a double helix
What was Watson-Crick Experimental design and conclusion
3D models and overall DNA structure (hydrogen and carbon bonds)
what is a nucleotide
a nucleic acid with a phosphate, sugar, and nitrogen base
what does DNA helicase do in DNA replication
it unzips or unwinds the parent DNA double helix
when helicase unzips the double helix what happens to the hydrogen bonds
it breaks them all (a,t,c,g)
when the helicase breaks the hydrogen bonds, what does this make
replication fork
what does DNA polymerase do in DNA replication
it adds new nucleotides bases
In what direction are the new nucleotides bases added in
5’ to 3’ direction
