what is the stomata?
the stomata is where the plants take in carbon dioxide and release oxygen and it’s located on the leaf.
where do light independent reactions occur?
the light-independent reactions happen in the stroma where they use energy from ATP and NADPH to convert carbon dioxide to glucose
what is the chemical equation for cellular respiration and what does each part represent.
Cellular respiration.
C6H12O6+6O2→6CO2+6H2O+ATP
C6H12O6=glucose
6O2=oxygen
6CO2= carbon dioxide
6H2O=water
ATP=adenosine triphosphate
what Is the chemical equations for photosythesis.
6CO2 + 6H2O → C6H12O6 + 6O2
6CO2=CD
6H2O=water
C6H12O6=glucose
6O2=oxygen.
where do light dependent reactions happen?
Light dependent reactions happen in the thylakoid membranes because they contain pigments such as chlorophyll
what is the purpose of photosynthesis and where does it occur?
The main purpose of photosynthesis is to get energy from sunlight and the produce glucose which provides energy for plants and it occurs in the chloroplasts.
what does rubisco do?
It attaches C02 and RUBP
carbon dioxide and ribulose bisphosphate.
what happens in PS1.
in ps1 the electrons get re-exited and then ATP synthase takes in electrons and combines it with Photosystem I takes the H+ ions and combines NADP+ and ADP with H+ ions, protons, and elecctrons to convert them into NADPH & ATP.
what is chlorophyll and what is its function
chlorophyll is a pigment found in plant cells and its function is to capture light
What is the light dependent reactions goal?
To produce ATP and NADPH for the LIR
what r the steps of the light dependent reactions.
I light hits ps2,electrons gets re-exited,water molecules split into 2 hydrogen ions and oxygen and electrons
electron carrier transport electron from ps2 to ps1 and it pumps H+ ion into thylakoid the H+ ions diffuse out through ATP synthase and turns ADP into ATP
and then we get oxygen from molecules splitting.
what is a photon?
a photon is a particle of light and its the unit of light.
what’s the goal of the Calvin cycle?
to produce glucose.
what are the steps for the Light Independent Reactions.
The LIR begin with combining CO2 and RUBP through rubisco to form 3-PGA which then are converted into G3P using energy from ATP and NADPH which some being G3P they are used to regenerate RUBP with the help of ATP and then remaining G3P molecules are converted into glucose.
