Where does all energy ultimately come from?
Where does all energy ultimately come from?
sunlight
What is step 1 of photosynthesis?
What is step 1 of photosynthesis?
capturing energy from sunlight
What is step 2 of photosynthesis?
What is step 2 of photosynthesis?
sunlight energy converted to ATP and NADPH
What is step 3 of photosynthesis?
What is step 3 of photosynthesis?
glucose is formed
What is step 3 called?
What is step 3 called?
the Calvin cycle
Name one of the two types of pigments in chloroplasts.
Name one of the two types of pigments in chloroplasts.
chlorophyll or carotenoids
How many electron transport chains are present in photosynthesis?
How many electron transport chains are present in photosynthesis?
2 (one that makes ATP and one that makes NADPH)
What happens to the two sugars produced in the Calvin cycle?
What happens to the two sugars produced in the Calvin cycle?
one is stored as energy, the other is used to start the cycle over again
How is ATP made during photosynthesis?
How is ATP made during photosynthesis?
as H+ diffuse through protein channels, a phosphate is added to ADP to make ATP
How are electrons used in the steps of photosynthesis?
How are electrons used in the steps of photosynthesis?
they pump H+ across thylakoid membranes creating a concentration gradient
What is the difference between aerobic and anaerobic respiration?
What is the difference between aerobic and anaerobic respiration?
aerobic requires oxygen, anaerobic does not
What is the starting reactant of glycolysis?
What is the starting reactant of glycolysis?
glucose
What is the final product of glycolysis?
What is the final product of glycolysis?
pyruvate
Where does pyruvate go when there is not oxygen present?
Where does pyruvate go when there is not oxygen present?
fermentation
What are the products of the Krebs cycle?
What are the products of the Krebs cycle?
NADH, ATP, FADH2
What is the first step of cellular respiration?
What is the first step of cellular respiration?
glycolysis
What is the second step of aerobic cellular respiration?
What is the second step of aerobic cellular respiration?
Krebs cycle
What is the third step of aerobic cellular respiration?
What is the third step of aerobic cellular respiration?
electron transport chain
How many ATP molecules are produced in all steps of cellular respiration?
How many ATP molecules are produced in all steps of cellular respiration?
glycolysis=4 or 2 net, Krebs=2, e- transport=34, fermentation=0
What are the reactants and products of both types of fermentation?
What are the reactants and products of both types of fermentation?
Lactic Acid: reactant = pyruvate, product = lactate; Alcoholic: reactant = pyruvate, products = ethanol and carbon dioxide
What is the difference between a heterotroph and an autotroph?
What is the difference between a heterotroph and an autotroph?
Heterotrophs need to eat food for energy, autotrophs make their own energy
What main product of photosynthesis is also the main reactant of cellular respiration?
What main product of photosynthesis is also the main reactant of cellular respiration?
glucose
Where does photosynthesis occur, and where does cellular respiration occur?
Where does photosynthesis occur, and where does cellular respiration occur?
photosynthesis = chloroplasts, cellular respiration = mitochondria

the hydrogen from split water molecules
Where do the electrons that enter the electron transport chain in cellular respiration come from?
Where do the electrons that enter the electron transport chain in cellular respiration come from?
NADH and FADH2
What are the products of each step of the Krebs cycle in cellular respiration?
What are the products of each step of the Krebs cycle in cellular respiration?
Step 1: acetyl-CoA, Step 2: CO2 and NADH, Step 3: NADH and ATP, Step 4: FADH2, Step 5: NADH
