Q

Coenzyme of photosynthesis

A

NADP+H (oxidized version)

NADPH (reduced version)

16
Q

Redox

A

Oxidation and reduction occurring at the same time

17
Q

Where do light reactions take place?

A

Grana (“photo” part of photosynthesis)

18
Q

Where do light independent reactions take place and what are thee names for them?

A

Stroma; carbon fixation, dark reactions, Calvin cycle

19
Q

Light dependent reaction, what occurs?

A

H2O is split through photolysis, O2 released, H reduces the NADP to NADPH, ATP is made

20
Q

Dark reactions, what occurs?

A

Enzyme Rubisco converts inorganic CO2 into organic glucose by combining 2 PGAL molecules (a 3 C molecule) using ATP from light reaction..waste products are NADP+ and ADP+P

21
Q

Reactants and products of light dependent?

A

Reactants: H2O sunlight NADP+
ADP+P
Products: ATP O2 NADPH

22
Q

Reactants and products of light INNdependent?

A

Reactants: CO2 ATP NADPH
Products: C6H12O6 ADP+P NADP+

23
Q

Photolysis

A

Breaking up of H2O in O2+H using sunlight

24
Q

Rubisco

A

Enzyme that converts PGAL and CO2 into C6H12O6
