Ap Bio Cellular Respiration

Front

What is cellular respiration?

Back

A metabolic process that converts glucose and oxygen into energy (ATP), carbon dioxide, and water.

Front

What are the three main stages of cellular respiration?

Back

Glycolysis, the Krebs cycle, and oxidative phosphorylation.

Front

Where does glycolysis occur in the cell?

Back

In the cytoplasm.

Front

What is the main product of glycolysis?

Back

Pyruvate, along with a small amount of ATP and NADH.

Front

What is the Krebs cycle also known as?

Back

The citric acid cycle.

Front

Where does the Krebs cycle take place?

Back

In the mitochondria.

Front

What is the primary function of the Krebs cycle?

Back

To produce electron carriers (NADH and FADH2) and ATP from the oxidation of acetyl CoA.

Front

What is oxidative phosphorylation?

Back

The process of ATP production that occurs in the electron transport chain, using energy from electrons carried by NADH and FADH2.

Front

What is substrate-level phosphorylation?

Back

A method of generating ATP by directly transferring a phosphate group to ADP from a phosphorylated intermediate.

Front

What is the role of NAD+ in cellular respiration?

Back

NAD+ acts as an electron carrier, accepting electrons during glycolysis and the Krebs cycle to form NADH.
