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
