Enzymes
What do enzymes do in the body
They speed up Chemical Reactions
What does ATP stand for?
Adenosine Triphosphate
Where does photosynthesis occur?
In the chloroplast.
Where does cellular respiration occur?
In the mitochondria.
What do plants give off that animals need?
O2
What are enzymes made of?
Proteins
What bond do we break to release energy in ATP?
In the bond between the last two phosphate groups.
What is the reactants for photosynthesis?
6CO₂ + 6H₂O
What is considered a waste product in cellular respiration?
O₂
What do gas do animals give off that plants need
CO2
What is the term for the specific area where a substrate binds to an enzyme?
The active site.
What happens when ATP breaks a bond?
It becomes ADP + P, and energy is released
What are the two stages of photosynthesis?
Light-dependent reactions and Light-independent reactions
What is the total ATP yield from one glucose molecule?
36-38 ATP
What type of energy starts this entire process?
Sunlight
What happens if an enzyme gets too hot or the pH is wrong?
They change shape and stop working (denatured)
What does ATP turn into after it releases energy?
ADP + P
What is created in the light-dependent reactions?
ATP, NADPH, and O₂.
What are the three phases of aerobic respiration
Glycolysis, Krebs Cycle, ETC
How are photosynthesis and respiration related?
The products of one are the reactants of the other.
Why is enzyme shape important?
They are picky - They only bind to one substrate
How does ATP become ADP and then back to ATP?
ATP releases energy, becoming ADP + P; energy from food rebuilds ATP again.
what are the products of photosynthesis?
C6H12O6 + O2
How does aerobic respiration differ from anaerobic respiration?
Aerobic uses O₂ and produces more ATP; anaerobic (fermentation) occurs without O₂ and makes less ATP.
How does Cellular Respiration and Photosynthesis help each other?
photosynthesis provides food & O₂; respiration releases ATP for cell functions.
