Where does glycolysis occur?

Cytoplasm

What is the net gain of ATP molecules in glycolysis?

2 ATP

What is the other name for the Citric Acid Cycle?

Krebs Cycle

Where does oxidative phosphorylation occur?

Intermembrane space and mitochondrial matrix

What are the two molecules that act as electron acceptors as part of cellular respiration?

Oxygen and NAD+

What can cells do when they don’t have oxygen for oxidative phosphorylation?

Fermentation

Where does oxidative phosphorylation occur within the mitochondria?

Intermembrane space

How many net ATP molecules are typically produced in total during cellular respiration?

30-34

What is the main purpose of glycolysis?

To break down glucose and convert it into pyruvate, producing a small amount of ATP.

Where does the citric acid cycle take place in eukaryotic cells?

In the mitochondria.

What is the final electron acceptor in the electron transport chain?

Oxygen.

Describe the process of oxidative phosphorylation.

It involves the coupling of electron transport chain and chemiosmosis to produce ATP.

Learn about the process of oxidative phosphorylation in the mitochondria, specifically in the intermembrane space and mitochondrial matrix. Understand the electron transport chain, integral proteins, co-enzymes, the ATP-ADP cycle, and the results of cellular respiration. Compare the ATP production between eukaryotes and prokaryotes.
