Overview
Glycolysis
Krebs Cycle
Electron Transport
No Oxygen
100

Breaking glucose to make ATP is this process, and it happens in this organelle.

Cellular respiration; the mitochondria

100

Breaking glucose for energy in the cytoplasm is this step.

Glycolysis

100

The cycle that keeps breaking glucose down toward CO₂ is this, also called these two names.

The Krebs cycle; TCA cycle and citric acid cycle

100

NADH and FADH₂ deliver electrons to this membrane system.

The electron transport system

100

Respiration with no oxygen and little ATP is this type.

Anaerobic respiration

200

Respiration that uses oxygen and makes lots of ATP is this type.

Aerobic respiration

200

2 ATP are spent in glycolysis; 4 ATP and 2 of this molecule are produced

NADH

200

Pyruvate loses a carbon as CO₂ and becomes this two-carbon piece, also called this.

Acetate; vinegar

200

The electron transport system sits in this mitochondrial membrane.

The inner membrane

200

Turning pyruvate into lactate is this path. 

Lactic acid fermentation

300

Aerobic respiration’s three steps are these.

Glycolysis, Krebs cycle, and electron transport chain

300

Glucose is split into two of these three-carbon molecules.

Pyruvate

300

That piece plus coenzyme A makes this molecule that enters the cycle.

Acetyl CoA

300

A protein that carries electrons in the chain is this.

A cytochrome

300

Turning pyruvate into ethanol is this path.

Alcoholic fermentation

400

The used-up form of NADH is this.

NAD⁺

400

NAD⁺ is the used-up form of this carrier.

NADH

400

That entry molecule to the Krebs cycle joins this four-carbon starter.

Oxaloacetate

400

Electrons drive protons into this space.

The intermembrane space

400

Lactate in muscle is tied to this sensation.

Burning

500

FADH₂ is another secondary carrier; its used-up form is this.

FAD

500

Glycolysis is the only aerobic step that does not happen in this organelle.

The mitochondria

500

The Krebs cycle first makes this six-carbon first product

Citric acid

500

Protons return through this enzyme to make 30-32 ATP

ATP synthase

500

Alcoholic fermentation takes place in this organism

Yeast
