Photosynthesis 2 Flashcards
What are the products of photosynthesis?
Glucose sugar and oxygen gas
How does a plant obtain the reactants needed for photosynthesis?
Light from the sun, Carbon dioxide from the atmosphere, and water absorbed from the earth.
What role is played by the hydrogen ions that were released from the water molecules?
They are added to NADP to make NADPH. Helps provide energy to make ATP.
What is the main photosynthetic pigment of photosynthesis?
Chlorophyll
Explain why chlorophyll appears green in color.
Because it does not absorb green light, so we see green, cause that is what is being reflected back to our eyes.
What is the role of chlorophyll in photosynthesis?
Chlorophyll, which resides in the chloroplasts of plants, is the green pigment that is necessary in order for plants to convert carbon dioxide and water, using sunlight, into oxygen and glucose.
Why is sunlight needed in photosynthesis?
To help produce sugar and oxygen, and provide energy to do so.
Name the part of the Leaf that is the primary region of photosynthesis.
The top of the Leaf just under the epidermis.
Explain what happens when sunlight hits chlorophyll molecules.
The energy from the light excites an electron from its ground energy level to an excited energy level.
What is the name of the electron carrier in photosynthesis?
NADP
What is the purpose of light dependent reaction?
To convert solar energy into chemical energy in the form of NADPH and ATP, used in light independent reactions and fuel the assembly of sugar molecules.
Name three substances that are formed when water molecules are broken down.
Oxygen, Hydrogen, and Electrons.
What happens to the oxygen released from the water molecules?
The Oxygen goes into the atmosphere
Describe what happens to the high energy electrons that are produced by photosystem 1.
Used to produce NADPH for he Calvin cycle
What is the name of the enzyme found in thylakoid membranes that is used to produce ATP?
Chloroplasts
