Q

Photosynthesis Chemical Reaction

A
  • Starts by taking sunlight energy and converting it into chemical energy (ATP & NADPH)
  • Then takes the chemical E (ATP and NADPH) and uses that chemical energy to power the production of sugar

Light travels in units of Energy called

21
Q

hese colors are usable light-Plants use Reds and Blues; but not green

22
Q

Main pigment found in all plants and algae.

A

Chlorophyll A

23
Q

Helps Chlorophyll A receive sunlight E

A

Chlorophyll B

24
Q

These are accessory pigments that help Chlorophyll A - these are orange or yellow pigments

A

Carotenoids

25
group of light absorbing pigments in thylakoid membrane
Photosystem
26
These colors are not usable
Reflection
27
Happens in cytoplasm. Everything that has cytoplasm can go through this process.
Glycolysis
28
Creates/Provides electron carriers
Kreb's Cycle
29
In this process electrons move two at a time toward oxygen
ETC - the electrons move down the ETC too
30
The final electron acceptor in ETC
Oxygen
31
Electron carriers
NADH & FADH2
