Overview on Photosynthesis Flashcards
(16 cards)
An important process
that makes life on Earth
possible.
Converts energy from
sunlight into chemical
energy stored in sugar
molecules.
Photosynthesis
Organisms that produces their own food (i.e., sugars)
Produces organic molecules from CO2 and other inorganic raw
materials from the environment.
“Producers”
also known as self-feeders
Autotrophs
2 Types of Autotrophs
Photoautotroph & Chemoautotroph
uses light as source of energy to synthesize organic
substances
Photoautotroph
gains energy from oxidizing inorganic substances
such as sulfur and ammonia
Chemoautotroph
Unable to make their own food
Depends on other organisms for food
“Consumers”
Heterotrophs
are housed in
a biological membrane
in early autotrophs
Photosynthetic enzymes
(i,e., photosynthetic
bacteria/prokaryotes
(cyanobacteria)).
Organelle in some
eukaryotic cells that aids
in the photosynthetic
process.
Contains the pigments
involved in the capturing
of photons from
sunlight.
Chloroplast
In plants, Chloroplasts are
usually found in
mesophyll cells
Photosynthesis reactants and products
Reactants:
Water
Carbon dioxide
Products:
Sugar
Oxygen
Two stages of photosynthesis
light reactions (photo stage of photosynthesis) and the Calvin cycle (synthesis stage)
________________________________ plays a crucial role in energy transfer by
converting to ____________________________
ADP (Adenosine diphosphate)
ATP (Adenosine triphosphate)
During the light-dependent reactions, ___________ is used to add a
phosphate group to ADP, producing ATP.
light energy
ATP, along with ____________________________ then powers the light-independent reactions (____________________) to convert carbon dioxide into _ _________
NADPH
Calvin Cycle
glucose/sugar
What happens to the ATP after the Calvin Cycle
it is converted back to ADP, which completes the cycle
is a crucial
coenzyme in photosynthesis, particularly in the light-dependent
reactions.
It acts as an electron acceptor, converting to NADPH, which then
delivers electrons and reducing power to the Calvin cycle, where
carbon dioxide is converted into sugar.
NADP+ or nicotinamide adenine dinucleotide phosphate
