AP Biology: Metabolism and ATP

Front

What is metabolism?

Back

Metabolism refers to the sum of all chemical reactions that occur within a living organism to maintain life, including catabolic and anabolic pathways.

Front

What are catabolic reactions?

Back

Catabolic reactions are metabolic processes that break down molecules into smaller units, releasing energy in the process.

Front

What are anabolic reactions?

Back

Anabolic reactions are metabolic processes that build larger molecules from smaller units, requiring energy input.

Front

What is ATP?

Back

ATP (adenosine triphosphate) is the primary energy carrier in cells, providing energy for various cellular processes.

Front

How is energy stored in ATP?

Back

Energy is stored in the high-energy bonds between the phosphate groups in ATP.

Front

What happens to ATP during cellular respiration?

Back

During cellular respiration, ATP is produced from ADP and inorganic phosphate through processes like glycolysis and oxidative phosphorylation.

Front

What is the role of ATP in metabolic pathways?

Back

ATP serves as a universal energy currency, driving various metabolic reactions and processes in the cell.

Front

What is the significance of phosphorylation?

Back

Phosphorylation is the addition of a phosphate group to a molecule, often activating or deactivating enzymes and proteins.

Front

What is the function of mitochondria in metabolism?

Back

Mitochondria are the powerhouse of the cell, where ATP is produced through aerobic respiration.

Front

What is cyanide's effect on ATP production?

Back

Cyanide inhibits the electron transport chain in mitochondria, preventing ATP production and leading to cellular energy failure.
