11-26 Flashcards
What are the reactants for the photosynthesis reactions?
Carbon dioxide water and light energy.
What are the products for the photosynthesis reactions?
Glucose sugar and oxygen gas.
How does a plant obtain the reactants needed for photosynthesis?
They absorb green light energy using chlorophyll.
What role is played by hydrogen ion released from the water molecules in photosynthesis.
It is the carrier.
What is the main photosynthetic pigment of photosynthesis?
Chlorophyll
Explain why chlorophyll looks green in colour.
.
It looks like that because it is reflecting all light but green. It absorbs the green light.
What is the role of chlorophyll is photosynthesis.
It absorbs energy from light.
Why is sunlight needed in photosynthesis?
Plants use it to convert water and carbon dioxide into food.
Main part of the leaf that is the primary region for photosynthesis.
Thylakoids.
What happens when sunlit hits chlorophyll molecules?
It absorbs it and it excites an electron.
What is the name for the electron carrier in photosynthesis?
NAD
What is the purpose of the light dependent reaction?
Convert solar energy into chemical energy.
Three substances that are made when water is broken down.
Hydrogen, electrons, and oxygen.
What is the name of the enzyme found in the thylakoids membranes that is used to produce ATP
Phosphate
