Bushman photosynthesis quiz

Photosystem 1

Converts light energy into chemical energy and is involved in light dependent reactions

Calvin Cycle

A light-independent reaction cycle that happens in the Stroma.

Antenna Complex

Proteins and chlorophyll that transfer light energy to the reaction center

Chlorophyll a

Reflects green light and plays role in photosynthesis

Chlorophyll b

Accessory pigment that passes captured light energy to cholophyll a

Primary electron acceptor

specialized molecule sharing the reaction center with chlorophyll a

Redox Reactions (Reduction Oxidization)

Happens when a molecule passes an electron to another molecule

Photophosphorylation

Makes ATP from ADP using light energy

P680

Photosystem 2 primary donor, it loses its electron or an electron donated by another antenna molecule

Electron Transport Chain (ETC)

A series of protein complexes and other molecules which transfer electrons from electron donors to acceptors with redox reactions

Electron transport chain location

Thylakoid membranes of chloroplasts

Adenosine Triphosphate (ATP)

Instant energy used to drive and support processes in cells

NADPH

Energy (can be stored) used to fuel process in cells and the Calvin cycle

What does the ETC of Photosystem 2 produce?

ATP

What does the ETC of Photosystem 1 produce?

NADPH

General Formula for photosynthesis

6H2O + 6CO2 + Light energy = C6H12O6 + 6O2

Antenna molecules

Light harvesting pigments

Noncyclic photophosphorylation

Process of making ATP from ADP using light energy

Accessory pigments

Light-absorbing pigments that support chlorophyll a

Granum (Plural Grana)

Stack of thylakoids

Chemiosmosis

Movement of ions across a membrane and assists in producing ATP

Cyclic photophosphorylation

Electrons transferred from ferredoxin to cytochrome complex in PSII, makes up ATP used in Calvin Cycle

When does cyclic photophosphorylation happen

In sunlight, when there is a demand for ATP without simultaneous production of NADPH or O2

How does chemiosmosis work

Hydrogen ions diffuse to the other side of the biological membrane from high to low concentration

Product of PSI

NADPH and ATP

ATP Synthase

Makes ATP using protons, ADP, and Pi

Photosystem 2

The first protein complex in light-dependent reactions of photosynthesis
