AP Biology- Enzymes and Energy

Front

What type of macromolecule are enzymes?

Back

Enzymes are proteins that act as biological catalysts to speed up chemical reactions.

Front

How do enzymes work?

Back

Enzymes lower the activation energy of a reaction, increasing the reaction rate.

Front

What type of reaction is represented by A + B --> AB + Energy?

Back

This is an exergonic reaction, where energy is released.

Front

What does catabolism describe?

Back

Catabolism is the process of breaking down large molecules into smaller ones.

Front

Where is energy stored in ATP?

Back

Energy is stored in the bonds between phosphate groups in ATP.

Front

What is the role of enzymes in biological reactions?

Back

Enzymes facilitate and accelerate chemical reactions without being consumed in the process.

Front

What is activation energy?

Back

Activation energy is the minimum energy required for a chemical reaction to occur.

Front

What is the difference between exergonic and endergonic reactions?

Back

Exergonic reactions release energy, while endergonic reactions require energy input.

Front

What is metabolism?

Back

Metabolism encompasses all chemical reactions in a cell, including both catabolism and anabolism.

Front

What is an example of a catabolic reaction?

Back

The breakdown of glucose during cellular respiration is an example of a catabolic reaction.
