Chemical Energy
This 3rd phosphate group is very unstable and can break off easily
ATP
MONO =
DI =
TRI =
MONO = One
DI = Two
TRI = Three
Photosynthesis happens in plant cells using ________
Chloroplasts
Chemosynthesis
Process that doesn’t use light energy, but finds chemical energy to use.
What factors that might affect the rate of photosynthesis?
Amount of water
Amount of sunlight
Type of light
CO2 levels
What is ATP (Adenosine triphosphate)?
Molecule that transfers energy from the breakdown of food particles to usable energy
True or False: ATP is reuseable
True, by adding another phosphate back into place
The light absorbing molecule inside chloroplasts
Chlorophyll
True or False: Chemosynthesis still uses ATP, but uses it from a different source
True
"Light is absorbed. Energy moved into thylakoid. Water broken down, oxygen released. Energy that was carried to thylakoid is moved to ATP."
What is this process?
Light-dependent Reactions/Photosynthesis/"The first half"
When is ATP used (two examples)?
Cellular respiration and Photosynthesis
What is a reactant? What is a product?
Reactant = Starting material, written on the left
Product = Ending material, written on the right
How do leaves connect to photosynthesis?
What makes chemosynthesis different to photosynthesis?
Chemosynthesis doesn't use light energy, while photosynthesis does
"Carbon Dioxide is added. Energy from step 2 used. Simple sugar is formed"
What is this process?
Light-independent Reactions/Calvin Cycle/"Second half" of the process
True or False: Proteins can be broken down as well for an energy source
True, though it's considered a last resort
Chloroplasts have 3 parts
Thylakoid , Grana, Stroma
What is the definition of photosynthesis?
Process that captures energy from the sun to make sugars that store chemical energy
What is stroma?
Stroma is contained in the extra space in the chloroplast, and the second half of the photosynthesis process takes place
True or False: There's only one type of chlorophyll
False: There's two types. Chlorophyll a and b
After Adenosine triphosphate releases the phosphate, then it will become _______________
Adenosine diphosphate
True or False: Plants tend to be green because they absorb green light very well, but not much red and blue, which is why most plants are green
False: It's the other way around. Plants tend to be green because they absorb red and blue light very well, but not much green
6 CO2 + 6 H2O makes C6H12O6 + 6 O2 with light energy. What are these chemicals?
6 carbon dioxide molecules and 6 water molocules makes a sugar molecule and 6 oxygen molocules
What are thylakoids?
Thylakoids are small coin-shaped membrane compartments that stack to form grana in chloroplasts. This is where the chlorophyll is contained.
True or False: Organisms that don't use photosynthesis don't depend on the sun.
False: Almost all life on our planet is dependent on the sun. Even if an organism doesn’t use photosynthesis itself, it requires eating the sugars made through photosynthesis of other organisms.
