|
Photoautotroph
|
Autotrophs that uses light to make food
|
Uses photosynthesis
Photoautotrophs covert light energy into carbon-based chemical energy |
|
|
Chemoautotroph
|
Autotroph that uses chemicals to make food
|
Humans are chemoautotrophs
Obtain energy threw oxidation |
|
|
Photosynthesis
|
The process of using sunlight to synthesize foods from carbon dioxide and water
|
We are reliant on photosynthesis for our energy
Photoautotrophs use photosynthesis |
|
|
Chloroplast
|
Found in plant cells, where photosynthesis happens
|
Chloroplast is in a photoautotrophic cell
Thylakoids are in it |
|
|
Thylakoid
|
Membrane made of chlorophyll
|
A stack of thylakoids are called granum
They are green |
|
|
Chlorophyll
|
Pigment that reflects back green light in the chlorophyll
|
Absorbs blue, purple, and red light
Chlorophyll is the reason that plants are green |
|
|
Grana
|
Two are more granums
|
A grana is made of thylakoid membranes
Inside the chloroplast |
|
|
Stroma
|
The fluid part of the chloroplast
|
Where the Calvin cycle takes place
Storms is a fluid |
|
|
Light reactions
|
Energy capturing reactions in photosynthesis
|
An example of a light reaction is when pigments absorb light energy
Also the splitting of water, and converting it to chemical energy |
|
|
Calvin cycle
|
The cycle that incorporated carbon dioxide in sugars during photosynthesis; uses chemical energy previously converted from light energy
|
Part of the Calvin cycle is making ATP
NADPH provides the protons and electrons needed to reduce the carbon dioxide |
|
|
NADPH
|
NADP+ with a hydrogen attached
|
The hydrogen comes from the water
NADPH provides the p & e needed to reduce carbon dioxide in the Calvin cycle |
|
|
PGAL
|
Is a sugar that results from three "turns" in the Calvin cycle
|
3 turns to get 3 carbons
Only autotrophs can take carbon out of the air |
|
|
Photoinhibition
|
A decline in photosynthesis
|
Caused by damage to chloroplasts
|
|
|
Saturation point
|
Compound to its full extent
|
No more substances can be absorbed
|
|
|
Limiting factors
|
Something that limits growth
|
Abundance of an organism
|
|
|
Rubisco
|
An enzyme in chloroplasts
|
Fixes atmospheric carbon dioxide during photosynthesis
Oxidizes the resulting compound during photorespiration |
|
|
Photo respiration
|
When plants take oxygen from the light and give out carbon dioxide
|
Opposite if photosynthesis
Like breathing but they get oxygen from the light |
|
|
C4 plants
|
4 carbon molecules present in the first product of carbon fixation
|
In the small subset of plants
|
|
|
Stomata
|
Tiny opening in the epidermis in plants
|
Gasses and water vapor passes through
Permits the absorption of carbon dioxide necessary for photosynthesis |
|
|
Aerobic cell respiration
|
Process in which our cells break down food and turn it into energy
|
Cells need the energy to perform life functions
Goes through the process, formula, and end results of aerobic cell respiration |
