photosythesis and cellular respiration review
Terms in this set (31)
distinguish between autotrophs and heterotrophs and give an example of each.
autotroph: organisms that make their own food (algae)
heterotroph: organisms that do not make their own food (people)
which type(s) of organisms carry out photosynthesis (autotroph/heterotroph)?
why are most plants green?
they contain chlorophyll; absorbs light, reflects green
name the organelle used in photosynthesis.
name the organelle used in cellular respiration.
write the balanced equation (words and formula) for photosynthesis.
carbon dioxide+water+light energy---->glucose+oxygen
write the balanced equation (words and formula) for cellular respiration.
what do the equations of photosynthesis and cellular respiration have in common?
photosynthesis requires the products of cellular respiration, cellular respiration requires the products of photosynthesis
what are the differences between the equations for photosynthesis and cellular respiration?
photosynthesis occurs in the chloroplast, cellular respiration occurs in the mitochondria; photosynthesis uses the calvin cycle, cellular respiration uses the krebs cycle
how are the two equations related?
reactants of one are products of the other
which type(s) of organisms carry out cellular respiration?
name the energy transfer molecule of the cell.
what are the three parts of an ATP molecule?
3. phosphate groups
energy is released from ATP when a phosphate group is...
plants get the energy they need for photosynthesis by absorbing...
what are the reactants for photosynthesis?
carbon dioxide, water, light
what are the products for photosynthesis?
what are the reactants for cellular respiration?
what are the products for cellular respiration?
carbon dioxide, water. ATP
how are aerobic respiration and anaerobic respiration different?
aerobic respiration requires oxygen, and anaerobic respiration does not require oxygen
what is fermentation? describe the two types.
anaerobic respiration that creates ATP.
lactic acid: humans, yogurt, cheese, sour cream
alcoholic: beer, wine, yeast
what happens if the intensity of light that a plant receives is increased?
what happens if the amount of carbon dioxide that a plant receives is increased?
what happens if the amount of water that a plant receives is increased?
what happens if the temperature a plant receives is increased?
photosynthesis increases until it gets too hot
state the purpose of photosynthesis.
to store energy
state the purpose of cellular respiration.
to release energy
name the two stages of photosynthesis, the reactants, the products, and location they occur.
light dependent: H2O, light; O2, ATP, NAPH; thylakoid
light independent (calvin cycle): CO2, ATP, NADPH; glucose; stroma
name the three processes of aerobic cellular respiration, where in the cell they occur, how many ATP they produce, and whether or not they require oxygen.
glycolysis: cytoplasm; 2 ATP; no
krebs cycle: mitochondria; 2 ATP; yes
electron transport chain: mitochondria; 32 ATP; yes
explain how photosynthesis and cellular respiration allows for carbon atoms to be cycled between plants and animals.
plants bring in CO2 and transform that carbon into glucose. animals eat those plants consuming the glucose and releasing CO2 back into the atmosphere after respiration.
describe how energy is transformed as it flows throughout the diagram.
plants capture light energy to create glucose in the form of chemical energy. animals then eat those plants, releasing that energy to be used for various processes, also releasing heat during the transformation.
