Name the pigment
Calvin-Benson Cycle
Photosystem and Light Reactions
100

Energy stores in chemical bonds of molecules

What is chemical energy?

100

Process in which light energy is transformed into chemical energy reducing CO2 to glucose.

What is Photosynthesis?

100

The 4 pigments of plants

What are Chlorophyll A, Chlorophyll B, Carotenoids, and Flavonoids?

100

This is how many times the cycle must run to get this many glucose molecules

What is 6 time for 1 glucose?

100

This is the first photosystem in light reactions.

What is Photosystem II?

200

Types of energy involved

What are kinetic energy and potential energy?

200

When a pigment absorbs light energy, an electron is raised to an orbital of a higher energy level, and electron goes from ground state to excited state

What are excited electrons?

200

absorbs blue-violet and red light

What is Chlorophyll A?

200

This is what the Calvin-Benson Cycle produces

What is G3P?

200

Re‑excites electrons arriving from PSII. Transfers electrons to NADP⁺ reductase, producing NADPH.

What is the process of photosystem I?

300

Chemical reactions involving gain or loss of electrons

What are oxidation-reduction reactions?

300

Light harvesting unit of thylakoid membrane

What is a Photosystem?

300

absorbs blue and orange light

What is Chlorophyll B?

300

Energy from the light reactions is transferred to sugar to produce glyceraldehyde-3- phosphate, creating a pool of G3P in the stroma.

What is the Reduction phase?

300

Splits water (photolysis) → releases O₂, H⁺, and electrons. Sends energized electrons into the electron transport chain (ETC). Helps generate the proton gradient that drives ATP synthesis.

What is the process of Photosystem II?

400

Name the 2 of the 4 reduction forms

What are NADH, NADPH, FADH2, ATP?

400

Where light reactions occur, what they do, and what they produce.

What is occurring in the thylakoid membranes, use light energy to split water, producing O2, ATP, and NADPH?

400

Carotenoids absorb this

What is blue-green light?

400

Carbon from CO2 is attached to a 5 carbon sugar using Rubisco

What is the Carbon fixation phase?

400

Purpose of the Cytochrome Complex (cytochrome b6f)

What is an electron transport chain carries electrons PSII to PSI? What aids in pumping H+ ions across membrane?

500

Name 2 of the 4 Oxidation forms

What are NAD+, NADP+, FAD, ADP/AMP?

500

Where carbon fixation reactions occur, what it uses,  and what it makes.

What is occurs in the stroma, carbon of CO2, ATP, NAPDH are used to make sugar molecules?

500

Flavonoids absorb this

What is ultraviolet light?

500

Describe the regeneration phase

What is some glyceraldehyde-3-phosphate from the stroma pool & ATP is used to remake RUBP for the cycle to continue, while the remaining G3P is used to make sugars?

500

Purpose of ATP synthase complex.

What passively pumps H+ ions across to produce ATP?
