100

This pigment absorbs most of the light energy used in photosynthesis.

Chlorophyll a

100

This cycle within the stroma of the chloroplast uses ATP and NADPH from the light-dependent reactions to fix carbon dioxide.

The Calvin Cycle

100

This 6-carbon sugar is the starting molecule for glycolysis

Glucose

100

This 3-carbon molecule, a product of glycolysis, enters the Krebs cycle to be further broken down.

Pyruvate

100

his series of protein complexes embedded in the mitochondrial membrane utilizes energy carriers from the Krebs cycle.

The ETC

200

These two photosystems work together in the light-dependent reactions, with photosystem II being the first to capture energy

PSII and PSI

200

The key enzyme in the Calvin cycle responsible for fixing carbon dioxide into organic molecules.

RuBisCO

200

This enzyme in glycolysis require an investment of ATP molecules to "prime" the sugar for breakdown, but ultimately generate more ATP later in the process

phosphofructokinase

200

This molecule combines with pyruvate to form the first molecule within the Krebs cycle.

Coenzyme A

200

These two main electron carrier molecules, generated in the Krebs cycle, transfer high-energy electrons along the chain

NADH & FADH2

300

Name some accessory pigments from this graph

Chlorophyll b and Beta-Carotene

300

This 5-carbon sugar is the initial acceptor for the fixed carbon in the Calvin cycle

RuBP

300

These electron carrier molecules are used in glycolysis to accept high-energy electrons and are regenerated for continued sugar breakdown.

NAD+

300

This series of chemical reactions in the mitochondria breaks down pyruvate into carbon dioxide, generating energy carriers.

Krebs Cycle

300

This process, driven by the electron transport chain, establishes a gradient of protons across the mitochondrial membrane

chemiosmosis

400

The transfer of a high-energy electron from an excited photosystem to an electron acceptor molecule

Electron Transport

400

Where does the Calvin Cycle happen?

Stroma

400

This net gain of energy molecules occurs during glycolysis, providing a small amount of cellular energy.

2 ATP

400

How many molecules of ATP are directly produced by one cycle of the Krebs cycle?

1

400

This enzyme complex within the electron transport chain uses the proton gradient to generate ATP from ADP and phosphate

ATP Synthase

500

These two key molecules are produced in the light-dependent reactions and used to power the Calvin cycle.

NADPH and ATP

500

While the light-dependent reactions capture energy, what is the primary function of the light-independent reactions?

To create sugars (Glucose)

500

What is the final product of glycolysis, a 3-carbon molecule that can be further broken down for energy or used in other cellular processes?

Pyruvate

500

These two key electron carrier molecules are generated in the Krebs cycle and used in the electron transport chain to produce most of the ATP in cellular respiration

NADH & FADH2

500

While the Krebs cycle produces some ATP directly, what is the main function of the electron transport chain in cellular respiration

to generate most of the ATP through chemiosmosis
