Biology 11/30 Flashcards
Name the three types of RNA and their function
mRNA: carriers genetic material the nucleus to the ribosome
tRNA: brings amino acids to ribosomes
rRNA: forms ribosomes
What is a codon?
3 nucleotides = 1 codon
What organelles make proteins ?
Ribosomes
What chemical process provides most of the energy used by life on earth?
Photosynthesis
Photosynthesis equation?
co2 HO2 sunlight C6H1206 O2
What are two traits of lights dependent reactions?
Can only occur in the daytime
Fills battery molecules with the energy from sunlight
What are two traits of both light dependent and independent reactions?
Transfers solar energy into chemical energy
Occurs only in producers
What are two traits of light independent reactions?
Can occur in daytime or night
Empties the energy of battery molecules into sugar
What is the function of light in photosynthesis?
Energizes electrons
In what organelle does photosynthesis occur?
Chloroplast
Example of long term and short term molecule
Long term: sugar
Short term: ATP
In what organelle does cellular respiration occur?
Mitochondria
Cellular respiration equation ?
C6H12O6 O2 CO2 H2O
Difference between aerobic and anatomical respiration?
aerobic requires oxygen and anaerobic does not
What kind of fermentation does yeast use?
Alcoholic
What produces the most ATP from a single sugar molecule?
Aerobic
What converts NADH back into NAD+, without collecting energy?
Fermentation: anaerobic
Splits a 6 carbon sugar into two 3 carbon molecules, and produces 2 ATP
Glycolysis: anaerobic and aerobic
Converts NADH into ATP
Electron transport chain: aerobic
Recycles 3 carbon product of glycolysis by splitting carbon-carbon bonds and releasing energy. Also produces co2
Kreb’s cycle aerobic
