Biology Chapter 8 Flashcards
a lower-energy molecule that can be converted into ATP by the addition of a phosphate group
ADP
main energy source that cells use for most of their work
ATP (adenosine triphosphate)
C in the picture
single thylakoid
What is an electron carrier molecule needed for transporting electrons from one part of the chloroplast to another?
NADP+
Why are electron carriers needed for transporting electrons from one part of the chloroplast to another?
High energy electrons are highly reactive (Their energy can be used to make NADPH & ATP.)
Photosynthesis uses sunlight to convert water and carbon dioxide into
high-energy sugars
What factors affect the rate of photosynthesis?
light intensity, temperature, water, carbon dioxide
Which of the following best explains the relationship between photosynthesis and cellular respiration?
The products of one are the reactants of the other.
In many plants, the rate of photosynthesis ____________________ when the weather becomes very cold.
decreases
Photosynthesis requires light, water, carbon dioxide, and ____________________.
chlorophyll
What is a product of the Calvin Cycle
high-energy sugars
The Calvin Cycle is another name for
light-independent reactions
Where do the light-dependent reactions take place?
in the thylakoid membranes
If you continue to increase the intensity of light that a plant receives, what happens?
The rate of photosynthesis increases and then levels off.
Finish the equation = 6CO2 + 6H2O yields …
C6H12O6 + 6O2
