|
|
|
What are the two reactions in photosynthesis?
|
light reactions
Calvin cycle |
|
|
Where do light reactions take place?
|
the thylakoids of the chloroplast
|
|
|
What is the energy from the light reactions used for?
|
to split the water molecule
|
|
|
What happens when the water molecule is split?
|
oxygen is given off as a waste product
|
|
|
What is some energy in the light reactions stored as?
|
ATP
|
|
|
What are the hydrogen atoms carried by in the light reactions and what do they become?
|
NADP+ and NADPH
|
|
|
What do the light reaction set up?
|
the dark reactions
|
|
|
What is not directly required for dark reactions?

What else can be produced besides glucose in the light reactions?
|
starch
|
|
|
Where do the dark reactions take place?
|
the stroma in eukaryotic cells

|
|
What happens to carbon dioxide in dark reactions?
|
it is absorbed by the photosynthetic organisms from its environmemt
|
|
|
What happens when the carbon dioxide is combined with hydrogen ions from the light reactions?
|
C6H12O6 is formed
|
|
|
What does glucose sugar require to be produced?
|
energy

|
|
What is an efficient way to store energy?
|
combining glucose into disaccharides and polysaccharides
|
|
|
What does the membrane in chloroplasts control?
|
movement of materials into and out of the organelle
|
|
|
What are thylakoids?
|
internal membrane systems consisting of flattened sacs, contain photosynthetic pigments and electron acceptors
|
|
|
What is grana?
|
stacked thylakoids, increased surface area, oriented for maximum sunlight absorption
|
|
|
What is stroma?
|
liquid solution surrounding the grana, contains DNA, RNA, ribsomes, and Calvin Cycle enzymes
