True
False
What is the role of light in the process of Photosynthesis
Light turns into sugar.
Light provides energy for breaking down sugar.
Light provides the energy for assembling small molecules into sugars
Light is sugar
carbon dioxide + water with sunlight ---> glucose
(sugar) + oxygen
What are the reactants?

water
carbon dioxide and water
glucose and oxygen
carbon dioxide + water with sunlight ---> glucose
(sugar) + oxygen
What are the products?
Light
Glucose
Carbon Dioxide and Water
Glucose and Oxygen
Chloroplasts are found mostly in the leaves of plants because the large surface area of leaves allows for maximum light absorption.
True
False

True
false
Which of the following is the correct sequence of events in cellular respiration?
glycolysis > fermentation > Krebs cycle
Krebs cycle > electron transport > glycolysis
glycolysis > Krebs cycle > electron transport
Krebs cycle > glycolysis > electron transport
What is the correct equation for cellular respiration?
6 O2 + C6H12O6 -> 6 CO2 + 6 H20 + Energy
6 O2 + C6H12O6 + Energy -> 6 CO2 + 6 H20
6 CO2 + 6 H20 -> 6 O2 + C6H12O6 + Energy
