distinguish between photoautotrophs and chemoautotrophs
- photoautotrophs: energy from sun
- chemoautotrophs: energy from inorganic chemicals
why is chlorophyll green?
reflects green light but absorbs other colors
why do leaves turn orange and yellow in the autumn?
green stops reflecting because it's too cold for the chlorophyll A & B to work so they die
explain the role of electron carriers in photosynthesis and give an example.
- store energy, transport to the electron transport chain.
- exp: ATP & NADPH
summarize how chemical energy is formed from light during photosynthesis
photosynthesis process absorbs light and uses water and carbon dioxide to form glucose energy. Does this through light dependent reactions and calvin cycle
what is the role of hydrogen ions in the conversion of ADP to ADP
they diffuse through the ATP synthase creating energy that allowed pi to bond to ATP
what does the calvin cycle do
- produces sugar & NADP
- produces it form CO2, ATP, NADPH
describe the relationship between the light dependent reactions and the calvin cycle
light dependent: produces what is necessary for the calvin cycle to occur
what is the equation for photosynthesis
6CO2+6H2O+(light) --> 6O2+C6H1206
what is the equation for cellular respiration
6O2+C6H1206 --> 6C02+6H2O+(energy)
list the three main stages of cellular respiration in order. Where does each stage take place in the cell?
- Glycolysis: cytoplasm
- Krebs Cycle: mitochondria
- (ETC): inner membrane of the mitochondria
describe the glycolysis in terms of energy input, output, and net gain of ATP
- input: 2
- output: 4
- net gain: 2
why is the krebs cycle also known as the citric acid cycle?
one of the molecules it forms is made of citric acid
what role does oxygen play in the electron transport chain?
it combines w/ hydrogen ions which combines w/ electrons to from water
what is the total net gain in ATP molecules per glucose molecule?
- 2: glycolysis
- 2: krebs cycle
- 32: ETC
give two examples of fermentation
saki, cramp in leg
what are the two types of fermentation? how do their products differ?
- alcoholic & lactic acid fermentation
- lactic acid: eukaryotes
- alcoholic: prokaryotes
lactic acid fermentation produces
alcoholic fermentation produces
what three sources of ATP does your body use during a long aerobic exercise session?
- krebs cycle
- fermentation (aerobic fermentation)
contrast photosynthesis with cellular respiration
complamentary. what one produces the other uses
how are photosynthesis and cellular respiration interdependent?
photosynthesis is produced by cellular respiration
