How is energy released from ATP? • Where is the chemical bondbroken to release energy?
How is energy released from ATP? Phosphate Bond Breaks • Where is the bond broken to release energy: At the bond between 2nd & 3rd Phosphates
ATP contains energy like a battery ADP + P (Uncharged Battery) ATP (Charged Battery)
What color wavelength is best for photosynthesis? Absorbed Light is Used Light BLUE
Why is green light not good for photosynthesis? Green is not absorbed It is reflected by the green chlorophyll (pigment/protein)

What is the equation for photosynthesis? _____+ _____+ _____ → _______ + ___ Use this to help you…. REACTANTS → PRODUCTS
What is the equation for photosynthesis? REACTANTS → PRODUCTS
What is oxygen in the photosynthesis process? WASTE PRODUCT!!
Who conducted the experiment that determined plant growth needed water and was important part of photosynthesis equation?
Van Helmont CO2 + H₂O→ Sunlight → C6H12O6 + O2
Who conducted the experiment that determined plants release oxygen (O₂) and was an important part of the photosynthesis equation?
Priestly (Think: Priests put candles in churches)
Who conducted the experiment that determined plants need sunlight and was an important part of the photosynthesis equation?
Who conducted the experiment that determined that photosynthesis had a cycle that created glucose from CO₂ and was an important part of the photosynthesis equation? CO₂ ? GLUCOSE
CO₂ GLUCOSE Calvin CO2 + H2O → Sunlight → C6H12O6 + O2
