photosynthesis is phun!
What form of energy is used to drive photosynthesis?
(sun)light
What are the three components of an ATP molecule?
Adenine, ribose, and phosphate
main product of photosynthesis
glucose
in the first stage of photosynthesis what gas molecule is released?
oxygen
waste product of photosynthesis
oxygen
name somewhere co2(carbon dioxide) comes from?
people, animals
process by which sunlight is used to make food
photosythiss
steps of Calvin cycle (Light independent cycle)
- Atp goes to the calvin cycle - Nadph goes to calvin cycle - CO₂ comes into the leaf from the air - C6h12o6, glucose is made (Red: needed by plant Green: made by plant)
steps of Photosynthesis (light dependent reaction)
- Sunlight shares on plant leaves - Plant uses wavelengths of visible light except green - Sunlight excites electrons in chlorophyll - Energy in electrons is used to make atp - Water is spilt to return to chlorophyll - Oxygen from the water is released into air - H(ydrogen) is added to NADP to make is NADPH
4 major accomplishments of photosynthesis
1. Glucose is produced 2. Oxygen released 3. light energy is converted to chemical energy 4. carbon dioxide is reduced
during the light reactions what two things are produced?
ATP and NADPH
Where is the energy stored in ATP?
Between the phosphate groups
Write the word equation for photosynthesis.
Carbon dioxide + water yelds glucose and oxygen in the presence of light
What form of energy is sunlight converted into?
Chemical energy
what stage is energy from sunlight is stored in ATP?
Light reaction
name a molecule that carries hydrogen to calvin cycle?
NADPH
Where does the oxygen released during photosynthesis come from
The splitting of water during light depended reaction b/c the plant takes the hydrogen from h2o and releases the oxygan
why are plants green?
bc the plant uses wavelengths of visible light but leaves out the green
stage of photosynthesis in which glucose is made?
calvin cycle
stage 2 of photosynthesis is called the?
calvin cycle (light independent reaction)
what are the 2 main functions of chloroplasts?
capture light energy and make chloroplast
what 3 things are used to make glucose in photosynthesis?
carbon dioxide, water, light energy
what molecule is needed in the calvin cycle?
carbon dioxode
green pigment
chlorophll
What is the name of the molecule that captures this energy?
chlorophyll
what is the primary pigment found in chloroplast?
chlorophyll
Where in the plant does photosynthesis take place?
chloroplast
what is the organelle where photosynthesis takes place?
chloroplast
during the first stage of photosynthesis what are excited?
electrons
during the calvin cycle what is produced?
glucose
what is produced in photosynthesis?
glucose
the first stage of photosynthesis is called?
light dependent reaction
What happens in each of the two phases of photosynthesis?
light dependent- captures light energy light independent- making of glucose
what type of energy dose the plant use to convert co2 and h2o into sugar?
light evergy
ATP
molecule that stores energy for cells
where do we get the air we breath?
plants
where the light independent reaction takes place.
stroma
what is needed to excite electrons?
sunlight
How are the light dependent and light independent reactions linked?
the light independent reaction needs atp, energy, and nadph from the light dependent reaction
what is photosynthesis?
the process by which sunlight energy is used by plants to make glocose
why do leaves appear green?
they reflect green light
where light energy is captured (light dependent reaction)
thylakoids
