Enzymes
What macromolecule are enzymes?
ATP stands for what?
Adenosine Triphosphate
All our energy originates from where?
Sun
The goal of photosynthesis is to create what molecule?
Glucose (sugar)
The goal of cellular respiration is to create what?
ATP
What is the difference between endothermic and exothermic reactions?
Endothermic reactions take in energy. Exothermic reactions give off energy.
What are the three parts of ATP?
Adenine, Ribose, 3 Phosphates
What are autotrophs?
Producers. Get energy from non living sources
What are the reactants of photosynthesis?
H2O and CO2
What are the reactants of cellular respiration?
Glucose and O2
What is the purpose of enzymes?
Speed up reactions
How does ATP release energy?
Breaks off the third phosphate
What kind of consumer eats both plants and animals?
Omnivore
What are the two steps of photosynthesis called?
1. Light dependent RXN (ETC)
2. Light independent RXN (Calvin Cycle)
What process happens first in cellular respiration?
Glycolysis
Where do enzymes bind their substrate?
Active site
Where does the cell create ATP?
How much energy is lost in each step of a trophic pyramid?
90% is lost. 10% is retained
What is released by the Light dependent RXN?
O2
What process will a cell use if no oxygen is available?
Anaerobic respiration (Fermentation)
How do enzymes speed up reactions?
Lower activation energy
How does your cell generate ATP?
Attach a third phosphate to ADP
What is the name for the fourth trophic level?
Where does the light independent RXN get its energy from?
Energy carrying molecules created by the Light dependent RXN. (ATP and NADPH)
What are the two steps of aerobic respiration called?
1. Citric acid cycle (Krebs cycle)
2. Electron Transport Chain
