Photosynthesis Flashcards

manufacture
are the organisms with the ability to use photosynthesis energy
autographs
What is the Photosynthesis equation
carbon dioxide+water+sunlight+glucose (energy)+oxygen
where does photosynthesis take place?
the leaf
is found at the underside of the leaf blade where carbon dioxide enters and oxygen exits the leaf
stoma/stomata
are organisms who cannot photosynthesis
heterotrophs
are organisms who cannot photosynthesis
heterotrophs
what does ATP stand for
Adenosine Triphosphate
energy-carrying molecule found in the cells of all living things. stores energy from photosynthesis or food
ATP
what does ADP stand for
Adenosine Diphosphate
an organic compound that is composed of adenosine and two phosphate groups. it is converted to ATP for the storage of energy during cell metabolism
ADP
What does NADP+
Nicotinamide Adenine Dinucleotide Phosphate
electron carrier and the chemical that forms NADPH
NADP+
what does NADPH stand for
Nicotinamide Adenine Dinucleotide Phosphate.
the reduced version of NADP+, which serves as a proton donor and electron carrier
NADPH
What are the stages of photosynthesis
the light-dependent reactions and the Calvin cycle.
where does the light-dependent stage occur
Occurs in the granum
specifically the thylakoid membrane.
what are the thylakoid membrane parts
PS1
PS2
ETC
ATP synthase
what is the process of photosynthesis (light-dependent reactions)
- Electrons get excited by sunlight in PSII making chlorophyll
- The excited electrons travel through the ETC
- Electrons lost in the chlorophyll of Photosystem II is replaced with the help of the process called “photolysis”.
- ETC transports electrons while the energy in electrons is used to pump hydrogen ions into the thylakoid creating a high concentration inside in the thylakoid
- When electrons reached the end of the first ETC, they go to photosystem I where light excites them once again.
- They travel down the second ETC where they finally get accepted by a molecule called NADP+.
- When NADP+ accepts electrons, it also accepts hydrogen forming NADPH.
- The high concentration of hydrogen ions inside the thylakoid is passively diffused by a protein called ATP Synthase. During this process, ATP synthase converts ADP into ATP adding one more phosphate group to its chain
What are the products of light dependent reaction
ATP
NADPH
O2
