Photosynthesis Flashcards
What does the LDR need
- Light-for energy
- NADP-is a coenzyme,H carrier,H comes from photolysis
- H20-broken down using the energy from light
What are the end products for the LDR
- ATP-from ADP+P
- NADPH2-carries H to Dark reaction
- O2- released into atmosphere
What happens to chlorophyll in the LDR
Absorbs energy and E becomes excited (goes to higher energy level)
What happens when E drop back
High energy is given off and can be used for photolysis (2H20-> 2H2+O2(^) split water

Calvin cycle
- What it starts with it also ends with ,
- light independent reaction
- occurs in stroma of chloroplasts
Dark reaction
Occurs in stroma
•is dense solution outside the grana
•enzymes found in liquidly solution
What does the dark reaction need
- ATP & NADPH2-from light reaction
* Co2-from atmosphere
End product of dark reaction
Carbohydrates-glucose
How can the dark reaction proceed
With or without light
What 3-c compound do CO2 and H combine to produce
PGAL-phosphoglyceraldehyde
PGALS
2 PGALS join to form 1 glucose (6 carbon compound)
What can glucose be used for
As energy source in cellular respiration
What can glucose be synthesized into to
Into other metabolic compounds
Such as sucrose,lipids,proteins,nucleic acids
What can glucose be converted into
Storage products or structural components by dehydration synthesis
Such as starch,cellulose
What can glucose be used for
The end product in a cell or transported to other tissues
What is photosynthesis
The process of capturing energy of sunlight and transforming it into chemical energy
What are the reactants of photosynthesis
CO2, H2O
What are the products of photosynthesis
Glucose, and oxygen
What is required for photosynthesis to happen
Pigments and enzymes in chloroplasts
What are photosynthetic pigments in plants capable of
Absorbing visible light of different wavelengths
What happens to light that photosynthetic pigments do not absorb
It either passes through or is reflected
What are photosynthetic pigments
Organic molecules which have a metal ion (magnesium) at the center
Which rays are at the end of the electromagnetic spectrum and have the shortest wavelengths and High frequencies
Gamma rays
Which rays are at the other end of the electromagnetic spectrum and have the longest wavelengths and low frequencies
Radio waves
Which Ray is near the center of the spectrum and has intermediate wavelengths and frequencies
Visible light
Where does the light dependent phase of photosynthesis occur
Thylakoid
Where does the light dependent phase of photosynthesis occur
Stroma
How are the light independent and light dependent phases linked
Light reaction makes NADPH and ATP energy and the dark reaction uses the energies
Where does the light dependent reaction occur
Within the grana; enzymes embedded in membrane
