Chapter 10-Photosynthesis Flashcards
needs oxygen (reactant) Carbon dioxide is produced (product)
Cellular respiration
Needs Carbon Dioxide (reactant)
Oxygen is produced (Product)
Photosynthesis
The conversion of light energy to chemical energy that is stored in sugar and other organic compounds is called
photosynthesis
These amke food by photosynthesis-feed themselves and most of the living organisms (producers)
Autotrophs
These obtain orgain material from other organisms (consumers)
Hetertrophs
The 2 stages of photosynthesis
- Light reaction
2. Calvin Cycle
The part of thr plant that is the major site of photosynthesis
Leaf
Within the cells of the plants, the organelles where photosynthesis actually takes place is called the
Hint:Surrounded by 2 memebranes
Chloroplast
Microscopic pores where carbon dioxide enters the leaf and oxygen exits is called
Stomata
Flattened membranous sac inside a choloplast that contain the molecular”machinery” used to convert light energy to chemical energy is called
Thylakoid
Thylakoid space that are stacked in colums that look like a stack of poker chips are called
Grana
ultimate goal of cellular respiration
energy in form of ATP
All catabloic reactions are
spontaneous reactions including aerobic and anaerobic respiration
oxygen given off by plants comes from
water
photosynthesis is endergonic or exergonic, anabolic or catabolic
Endergonic and anabolic(building up)
in the light reaction solar energy is convereted to
chemical energy
light reaction produce no
sugar
In photosynthesis sugars are imported because they convert light energy to chemical energy in the form of 2 compounds:
ATP and NADPH
These 2 compounds are used to provide the energy for the Calvin Cycle
ATP and NADPH
Calvin cycle begins by incorporating____from the air into organic molecules already present in the chloroplast
Carbon Dioxide
The Calvin cylce makes sugar witht the help of _____ and _____ which are produced by light reactions
ATP and NADPH
In photosynthesis light reaction occur in the
thylakoid of the chloroplast
in photosynthesis the calvin cycle occurs in the
stroma
which light colors work best for photosynthesis
Red or Blue
When a photon(burst of light) hits an electron, it goes to an “excited state” which is unstable. When the electron drops back down to the ground state orbital, excess energy is released as
Florescence
Calvin Cycle: Anabolic or catabolic
Anabolic
Calvin Cylcle: Consumes energy or produces energy
Consuemes energy–Endergonic
Carbon enters Calvin Cycle in form of carbon dioxide and leaves in the form of
sugar
carbohydrate produced directly from the Calvin Cycle is actually not glucose, but it is a
3 Carbon Sugar called glyceraldenyde-3-phosphate (G3P)
to synthesize 1 glucose molecule, the Calvin cycle uses how many molecules of carbon dioxide, AT, and NADPH?
6-Carbon Dioxide
18-ATP
12-NADPH
A cell can have up to how many chloroplast
30-40
Photosythesis=
light reaction
Calvin Cycle=
synthesis
During what cycle are 10 million molecules of ATP consumed and regenerated
ATP cycle
What is the shuttling of inorganic phosphate and energy
ATP cycle
this process couples the cells exergonic reactions to the cells endergonic reactions
ATP cycle
a chemical reaction that has a positive delta G is correctly described as
endergonic
which process in eukaryotic cells will proceed normally whether oxygen is present or absent
Gylcoysis
How many oxygen molecules are required when 2 molecules of glucose are completely oxidized via aerobic respiration
12
where is most of the ATP generated during cellular respiration
oxidative phosphorylation
leaf looks green because
absorbing voilet-blue and red light while reflecting the green light
