Q

Photosynthesis (Energy, Where is occurs, what can do it, how do they feed themselves)

A

Solar energy to produce chemical energy
Occurs in the chloroplast
Plants, algae, and some bacteria can do this

Inner membrane folds are called the

A

Cristae - They increase the surface area

23
Q

Metabolism Reactions

A

Anobolic- builds up large molecules into smaller ones (requires energy)
Catobolic- breaks down large molecules into smaller ones (releases energy) (Cut into smaller pieces)

24

Q

Reduction

A

Gain of electrons

28
Q

Gain of electrons

A

Reduction

29

Oxidation and reduction together

30
Q

Overall photosynthesis is a ( ) reaction

A

Reduction

31
Q

Overall cellular respiration is a ( ) reactions

A

Oxidation

32
Q

Two different reactions that take place in photosynthesis

Q

3 Energy rich molecules are in involved in photosynthesis

A

Glucose, ATP, NADPH

34
Q

ETC

A

Electron Transport Chain

35
Q

Reducing power

A

Causes reduction - gives away an election (oxidation)

36
Q

Reduced

A

Gains an electron

37
Q

NADP does?

NADPH does?

A

Is an electron acceptor

Is an electron giver/donor

38
Q

What is ATP and what is it called to remake it?

A

Stores chemical energy

Remaking ATP is phosphorylation

39
Q

Glucose

A

Energy transport molecule

40
Q

LIght Dependent Reactions Stages 1 and 2

A

1: Solar energy is transferred to an electron and you start an electron transport chain
2: Make ATP and NADPH by transferring electrons

41
Q

LIght Independent Reaction Stage 3

A

When you form energy rich glucose

42
Q

Light Reactions occur in the

A

Thylakoid membrane

43
Q

Chlorophyll and other pigments do what

A

Absorb light energy

44
Q

In order to replace electrons….

A

Water molecules are split (photolysis) and oxygen is given off

45

Photosystem

A

1 (P700) and 2 (P680). The absorb different wave length

46
Q

LEO says GER

A

Losing Electrons Oxidation and Gaining Electrons Reduction

C3 must be converted to a ( ) by ( ) then reduced by?

What does this then turn into? And what is it used for?

A

High energy state by being activated by ATP and reduced by NADPH
PGAL (some goes to make glucose or move to stage 3)

52
Q

How many times is the Calvin Cycle completed to produce one glucose?

A

Six times.
