Flow of Energy Flashcards
(18 cards)
What form of energy do cells use?
ATP
To release energy the third phosphate group is broken off ATP, and the molecule becomes _______, which can be “recharged”
ADP
What is the difference between autotrophs and heterotrophs?
Autotrophs - produce their own glucose
Heterotrophs - obtain glucose from their diet
What is photosynthesis?
The process where light energy from the Sun is converted to chemical energy
What are the THREE reactants of photosynthesis?
CO₂ + H₂O + light energy
What are the TWO products of photosynthesis?
C₆H₁₂O₆ + O₂
Who is able to perform photosynthesis? List at least two.
Plants and algae
What organelle does photosynthesis occur in?
Chloroplast
What are the two steps of photosynthesis? Include inputs and outputs for each.
-Light reaction inputs- H₂O + light energy outputs- oxygen
-Calvin Cycle inputs- CO₂ outputs- Glucose
Why are photosynthesis and cellular respiration complementary processes?
The reactants of photosynthesis are the products of respiration and vice versa
What is cellular respiration?
The process of breaking down glucose into ATP for energy used by the cell
Where does cellular respiration occur in the cell?
Mitochondria
What are the TWO reactants of cellular respiration?
C₆H₁₂O₆ + O₂
What are the THREE products of cellular respiration?
Energy, CO₂ and H₂O
Where do organisms get the reactants for cellular respiration from?
Eating food, photosynthesis, in the atmosphere
What are the three steps of cellular respiration? Include inputs and outputs for each.
-Glycolysis: inputs- glucose output- 2 half glucose molecules
-Krebs Cycle: inputs- 2 half glucose molecules outputs- CO₂ + ATP
-ETC: inputs- O₂ outputs- ATP, H₂O
What process occurs when oxygen runs out?
Fermentation
What is the equation for photosynthesis
6CO2 + 6H2O + Light energy —> C6H12O6 + 6O2
