24
Q

DNA or RNA: long term storage of genetic information

25
Q

DNA or RNA: single helix

26
Q

DNA or RNA: it is synthesized from dna

27
Q

DNA or RNA: self replicating

28
Q

DNA or RNA: used to transfer genetic info on organisms

29
Q

dna to dna

A

dna replication

30
Q

dna to rna

A

transcription

once the dna is replicated, at the same time an RNA copy is also happening

31
Q

start codon

A

AUG (methane) there is no protein synthesis without this

32
Q

stop codons

A

UGA, UAG & UAA

33

36
Q

energy capture
process of converting light energy to chemical energy and storing it in the form of sugar (glucose)

A

photosynthesis

37
Q

stored energy in plants
long chains of glucose molecules in plants

38
Q

long chains of glucose molecules in animals

39
Q

formula of photosynthesis

A

CO2 +H2O -> C6H12O6 + O2

40
Q

found in most photosynthetic eukaryotes and plants. used for photosynthesis. main site where photosynthesis happens. makes energy

A

chloroplast

41
Q

found in most eukaryotes. used for cellular respiration. it breaks down glucose to make ADP

A

mitochondrion

42
Q
  • system that is suspended in the stoma and a collection of membranous sacs
  • where you can find chlorophyll
  • site of light dependent reactions
43
Q
  • the aqueous field
  • sight of light independent reaction
  • is a colorless alkaline aqueous protein rich fluid present int eh inner membrane of the chloroplast
44
Q
  • stacked thylakoid
  • where you can find stroma
45
Q

factors that affect photosynthesis

A

light intensity, carbon dioxide, temperature, water

46
Q

as the light increases, the ___ the rate of photosynthesis is especially in the light dependent reaction

47
Q

as the carbon dioxide increases, the ___ the rate of photosynthesis is especially in the light dependent reaction

48
Q

temperature to have a good rate of photosynthesis

A

25 to 30 degrees celsius

49
Q

important in the adequacy of water in the cell and on the opening and closing of

50
Q
  • Calvin cycle
  • takes place in the storm
  • do not require light energy because the dark reaction happens at night
A

light independent reaction

51
Q

This occurs in the stroma. Carbon dioxide is present in the stroma, as well as RuBP. These two need to be together. They will come together with the help of Rubisco, bringing them both together. And now, you can make 6 carbon molecules. RuBP has 15 carbons. Carbon dioxide has 3 carbons. This equals 18 Carbons. This is too big, so it needs to be divided into two. It becomes 3-Phosphoglyceric Acid / 6 3-PGA. This ends the process because it is now usable.

A

carbon fixation

52
Q

where does carbon fixation occur

53
Q

what are present in the stroma

A

carbon dioxide and RuBP

54
Q

how many carbons does RuBP have

55
Q

how many carbons does carbon dioxide have

56
Q

This equals 18 Carbons. This is too big, so it needs to be divided into two. it becomes

A

3-phosphoglyceric acid / 6 3-PGA
