Biology Chapter 9
What is the starting materials for the calvin cycle?
3 ATP molecules and 2 NADPH molecules
What's the balanced equation for photosynthesis?
6CO2 + 6H2O ------> C6H12O6 + 6O2
What are the two energy rich compounds that are produced by the light reactions?
ATP, NADPH
The products of the light-dependent reactions of photosynthesis are
ATP,NADPH, and oxygen
How do those glucose molecules get into animals? what happens when they get into animals?
Animals eat plants, it creates energy
What is another name for the calvin cycle?
C3 cycle
In what organelle does photosynthesis take place?
Chloroplast
What is the purpose of cyclic electron flow?
It supplies electrons for photosystem I.
_________ is the final electron acceptor in photosystem I.
NADP+
What is the chlorplasts features name them
Outer membrane,Inner membrane, Thylakoid , Stroma
The difference between P700 and P680 is that
P700 absorbs light with a wavelength of 700 nm.
What is the term of organisim?
a single cell life form
When a photon of light energy reaches a reaction center chlorophyll molecule, what becomes excited?
an electron
Why do leaves look green?
chlorophylls absorb all wavelengths but green; green is reflected
What is the pigment found in chloralplasts?
chloryphll
what is a energy rich sugar molecule produced from the calvin cycle
glucose
What is the color of chlorphyll
green
what is the worst color light for photosyntheisis
green
When electrons are passed through an electron transport chain, released energy
is transformed into a hydrogen ion gradient to drive ATP synthesis.
in photosyntheisis what energy conversion takes place?
light energy is converted to chemical energy in form of sugars (glucose)
In Priestley's experiments, what was released by the mint sprig and allowed the candle to burn again?
oxygen
This molecule results in the production of_________ gas.
oxygen
Light-harvesting complexes, excited by photons of light, are made of
protiens, cofactors ,and pigment
The products of photosyntheisis are?
sugar and oxygen
Define photosynthesis?
the process by which green plants and some other organisms use sunlight to synthesize foods from carbon dioxide and water.
Why do plants appear green
they reflect green light
