AP Bio 7.1 and 7.2 Flashcard

Front

What is substrate level phosphorylation?

Back

A mode of ATP synthesis that occurs when an enzyme transfers a phosphate group from a substrate molecule to ADP.

Front

What happens to the reducing agent in a redox reaction?

Back

The reducing agent loses electrons and loses potential energy.

Front

What is fermentation?

Back

A catabolic process that involves the partial degradation of sugar without oxygen.

Front

What are the reactants of cellular respiration?

Back

Sugar and oxygen.

Front

What is a catabolic pathway?

Back

Metabolic pathways that release stored energy by breaking down complex molecules.

Front

What is oxidative phosphorylation?

Back

A process that uses energy from the electron transport chain to produce ATP.

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.

Front

What is glycolysis?

Back

The metabolic pathway that converts glucose into pyruvate, producing a small amount of ATP.

Front

What is the Krebs cycle?

Back

A series of chemical reactions used by all aerobic organisms to generate energy through the oxidation of acetyl-CoA.

Front

What is the electron transport chain?

Back

A series of protein complexes in the inner mitochondrial membrane that transfer electrons and pump protons to create a proton gradient.
