Chapter 10 Photosynthesis
What are the 3 stages of the calvin cycle?
(1) carbon fixation (2) reduction and sugar (G3P) production and (3) regeneration (of RuBP)
What are the reactants for the light-dependent reactions?
ATP, NADPH, CO2
What are the products of the light-dependent reactions and where do they occur?
ATP, NADPH, and O2, in the Thylakoid membrane (proton gradient established in Thylakoid lumen)
Write the full balanced equation for cellular respiration
C6H12O6 + 6 O2 + → 6 CO2 + 6 H2O + 32 ATP
Rubisco catalyzes which reaction in the C3 cycle?
Carbon Fixation (RuBP + CO2 --> 2PGA)
The 3 carbon sugar molecule that is produced after multiple cycles of the Calvin cycle is called ____.
G3P
What are the products of the light-independent reactions?
G3P (used to make glucose), ADP, NADP+
Which color has more energy per photon? Red or Blue?
Lower wavelengths have higher energy
What is the type of phosphorylation of APT called that results from energy derived from photons?
Photophosphorylation
Name the enzyme that fixes carbon dioxide
Rubisco
What is the most abundant protein on the planet?
Rubisco
ATP synthase is found where in the chloroplast?
Thylakoid membrane
What is the function of chlorophyll?
To absorb photons (particles of light) and transfer that energy to electrons in the electron transfer system (which then produces a hydrogen ion gradient which powers ATP synthesis and generates NADPH)
pigment
a molecule that absorbs light
As wavelength increases, the energy of a photon ___________.
decreases
C4 plants are well adapted to _________________.
dry and hot conditions
Once a molecule absorbs a photon, its electron moves from the ground state to an _________________ state.
excited
Which color is generally NOT responsible for driving photosynthesis?
green
chlorophyll
primary pigment in photosystems
What are the reactants and products of the light-dependent reactions?
reactants: H2O, ADP, NADP+ products: O2 NADPH, APT
carotenoids
secondary pigments
the pores in a leaf that allow for gas exchange
stomata
Where are the carotenoids located?
thylakoid membrane
