2.26 and 2.27 Glycolysis and Krebs Cycle

Front

What is glycolysis?

Back

Glycolysis is the metabolic pathway that converts glucose into pyruvate, producing a small amount of ATP and NADH in the process.

Front

Where does glycolysis occur in the cell?

Back

Glycolysis occurs in the cytosol of the cell.

Front

What is the end product of glycolysis?

Back

The end product of glycolysis is pyruvate.

Front

What is the primary purpose of glycolysis?

Back

The primary purpose of glycolysis is to convert glucose into pyruvate.

Front

What is substrate-level phosphorylation?

Back

Substrate-level phosphorylation is the direct transfer of a phosphate group to ADP to form ATP.

Front

What is NADH?

Back

NADH is the reduced form of NAD+, an electron carrier that stores energy.

Front

At the end of the Krebs cycle, where is most of the energy from glucose stored?

Back

Most of the energy from glucose is stored in NADH.

Front

What is the Krebs cycle also known as?

Back

The Krebs cycle is also known as the citric acid cycle.

Front

Where does the Krebs cycle occur?

Back

The Krebs cycle occurs in the mitochondrial matrix.

Front

What is the role of FADH2 in cellular respiration?

Back

FADH2 is an electron carrier that donates electrons to the electron transport chain.
