Cellular Respiration: Inputs and Outputs by Stage

Practice vocabulary flashcards detailing the cellular respiration stages, their specific intracellular locations, and their primary inputs and outputs.

Glycolysis

The metabolic stage occurring in the Cytosol / Cytoplasm that takes Glucose, $2\text{ NAD}^+$, $2\text{ ADP}$, and $P_1$ as main inputs, and produces $2\text{ Pyruvate}$, $2\text{ NADH}$, and $2\text{ ATP (net)}$ as main outputs.

Pyruvate Processing (Prep Step)

The stage occurring in the Mitochondrial Matrix that takes $2\text{ Pyruvate}$, $2\text{ CoA}$, and $2\text{ NAD}^+$ as main inputs, and produces $2\text{ Acetyl-CoA}$, $2\text{ CO}$, and $2\text{ NADH}$ as main outputs.

Citric Acid Cycle (Krebs Cycle)

The stage occurring in the Mitochondrial Matrix that takes $2\text{ Acetyl-CoA}$, $6\text{ NAD}^+$, $2\text{ FAD}$, and $2\text{ ADP}$ as main inputs, and produces $4\text{ CO}_2$, $6\text{ NADH}$, $2\text{ FADH}_2$, and $2\text{ ATP (or GTP)}$ as main outputs.

Electron Transport Chain & Oxidative Phosphorylation

The stage occurring in the Inner Mitochondrial Membrane that takes NADH, $FADH_2$, $O_2$, ADP, and $P_1$ as main inputs, and produces ATP, $H_2O$, $NAD^+$, and FAD as main outputs.

Cytosol / Cytoplasm

The cellular location where Glycolysis takes place.

Mitochondrial Matrix

The cellular location where both Pyruvate Processing (Prep Step) and the Citric Acid Cycle (Krebs Cycle) take place.

Inner Mitochondrial Membrane

The cellular location where the Electron Transport Chain & Oxidative Phosphorylation take place.
