Q

what is needed in light independent cycles

A

atp

23
Q

plants that use the calvin bensis cycle are called what?

A

c3

24
Q

when the stomato is closed on c3 plants what happens?

A

oxygen builds up and binds to ribisco and cant do its job right

25
Q

fix carbon in two different cell types

A

c4 plants

26
Q

c4 plants: co2 —> 4 carbon compound, 4 carbon compound is delivered to other cell type. finish out the sequence

A

—(enzyme)–> —(riblose)–> co2 –> carbon bensin cycle

27
Q

CAM plants fix carbon at what times

A

2 a night

28
Q

what does the stomato do at night in cam plants?

A

opens and fixes carbon dioxide —>crassalation acid

29
Q

what do cam plants do during the day?

A

stomato closed, crassalation acid –>co2—> c-b cycle

30
Q

types of plants that dont use photosynthesis

A

indian pipe, beech drops, dooder, and love vine

31
Q

what two plants steal glucose from host plant

A

dodder, love vine

32
Q

what two plants are heterotrophic

A

indian pipe, beech drops

33
Q

what is the goal of respiration

A

atp

34
Q

where does respiration take place?

A

mitochondria

35
Q

name 3 types of respiration and the in between one too

A

glycolysis, krebs cycle, electron transfer phosphorolation, (transition reaction)

36
Q

where does glycolysis take place?

A

cytoplasm

37
Q

what happens in glycolysis? and how much atp is produced

A

glucose is broken down into two pyruvate molecules, actually 4 but only 2 due to 2 have to be used up (NET 2)

38
Q

what is made in the transition cycle?

A

NADH

39
Q

why does the transition cycle exist?

A

pyruvate must be formed into different molecule before entering the krebbs cycle

40
Q

where does the krebs cycle take place? and how much atp is produced?

A

matrix of mitochondria, 2 ATP

41
Q

where does electron transfer take place in eukaryotes?

A

crystie

42
Q

in prokaryotes where does ETP take place?

A

plasma membrane

43
Q

what brings the electrons into the transfer chain?

A

FADH

44
Q

what is the final electron accepter?

A

oxygen

45
Q

as electrons pass to other molecules what do the energy levels do? and what happens?

A

drop, dropped energy levels move H+ ions outside the crystie

46
Q

H+ ions flow back into the crystie due to what? what do they form?

A

concentration gradient they form a protein

47
Q

how many molecules do ETP form?

A

32

48
Q

what happens when you mix electrons, oxygen, and hydrogen

A

water

49
Q

situation of respiration without oxygen is called?

A

fermentation (anarobic respiration)

50
Q

how does fermentation include glycolysis?

A

(cytoplasm) after glycolysis, pyruvate gets broken down into other stuff

51
Q

name two types of fermentation

A

alcoholic, lactate

52
Q

alcoholic fermentation formula

A

pyruvate–> ethanal + CO2

53
Q

lactate fermentation lacs what?

A

o2

54
Q

our muscles use what type of fermentation and why

A

lactate, white muscle fibers dont have mitochondria cant undergo arobic respiration so go under lactate fermintation
