cellular respiration & photosynthesis test Flashcards
 where is food and energy stored
Chemical bonds
what is chlorophyll
A green pigment found in chloroplast that absorb light energy
what are chloroplast
plant organelles that are found in the leaves
what are the reactants of photosynthesis
6co2 + 6h2o + sun
what are the products of photosynthesis
c6h12o6 + 6o2
what is a light dependent reaction and where does it take place
Solar energy being used to create ATP, takes place in the thylakoids
what is the equation for glucose
c6h12o6
what are light independent reactions and where do they take place
carbon dioxide is used to produce sugar, no light is required, and it takes place in the stroma
What is the function of the stomata
stomata control gas exchange within the leaves
Why did the leaves change color in the fall
there is less sunlight meaning less chlorophyll. in this case the carotenoids are used
what is cellular respiration
The use of oxygen to break down glucose and create ATP
where does cellular respiration occur
Mitochondria
what are the three parts of aerobic respiration
glycolysis, Krebs cycle, electron transport chain
describe glycolysis
anaerobic, produces two pyruvate‘s, And produces to ATP
what is a pyruvate
A six carbon glucose broken in half into two 3 carbon molecules
how many ATP are produced in the Krebs cycle
2
how many ATP are produced in the electron transport chain
32-34
how many ATP can be produced from one molecule of glucose
38
what is the equation for cellular respiration
c6h12o6 + 6o2 > 6co2 + 6h2o + ATP
what is fermentation
an anaerobic process that allows glycosis to continue when oxygen isn’t available
what are the two types of fermentation
lactic acid and alcoholic
where can lactic acid fermentation be felt
muscles
what is produced an alcoholic fermentation
ethyl alcohol, co2, single called organisms
what three factors affect photosynthesis
temperature, light intensity, and water availability
