LIGHTENERGY
How do plants capture light energy?
How do plants capture light energy?
Plants have special light absorbing molecules called pigments that can capture light energy from the sun. The main pigment of photosynthesis is chlorophyll

CHLOROPLAST
What is the purpose of photosynthesis?
What is the purpose of photosynthesis?
• To change light energy from the sun into chemical energy
• To change inorganic materials into organic products that can be used as FOOD energy.

•Temperature•pH
What happens to an enzyme when it goes too far past its optimum temperature or too far out of its pH
range?
What happens to an enzyme when it goes too far past its optimum temperature or too far out of its pH range?
• The enzyme LOSES ITS SHAPE and can no longer catalyze a chemical reaction
Explain how an enzyme works like a lock and key.
Explain how an enzyme works like a lock and key.
• Each enzyme has a specific shape that fits a specific substrate.
How many different chemical reactions can an enzyme catalyze?
• JUST ONE type of chemical reaction!• Each enzyme only fits ONE type of reactant
that fits its specific shape!
