Q

what is the chemical equation of photosynthesis?

A

6CO2 + 6H2O (sunlight->) C6H12O6 + 6O2

carbon dioxide + water -> sugar (carbohydrate) + oxygen

16
Q

what is oxidation?

A

the loss of electrons and hydrogen ions (or the gain of oxygen)

17
Q

What is stage one of photosynthesis

A

light reaction; light energy is turned into chemical energy and O2 through the thylakoid membrane

water is split to make O2

18
Q

What is made when H ions are reduced in NADP+

A

NADPH

19
Q

What cycle is NADPH traveled to

A

The calvin cycle

20
Q

What is used to power the calvin cycle

A

Light reaction generates ATP which provides chemical energy for the calvin cycle

21
Q

What kind of energy does sunlight contain?

A

Electromagnetic energy / radiation

22
Q

What do Electromagnetic energy travel in?

A

waves

23
Q

The shorter the wave…

A

the greater the energy

24
Q

pigments…

A

are where light molecules are absorbed and are built into the thylakoid membrane

25
Q

different wave lengths could…

A

result in different color shown in the plant

26
Q

in the carbon cycle, what do photosynthesis and cellular respiration share?

A

products and reactants (formula reversed)
