Thermodynamics and Enzyme Reactions Flashcard

Front

What is an exergonic reaction?

Back

An exergonic reaction is a type of chemical reaction that releases energy, often in the form of heat or light.

Front

What is an endergonic reaction?

Back

An endergonic reaction is a type of chemical reaction that requires energy input to proceed.

Front

What is entropy?

Back

Entropy is a measure of disorder or randomness in a system, often associated with the amount of energy unavailable for doing work.

Front

What happens to energy in a system during a reaction?

Back

Energy is often lost as heat during reactions, making it non-recyclable.

Front

What is chemical potential energy?

Back

Chemical potential energy is the energy stored in the bonds of chemical compounds, like coal or food.

Front

What is a catabolic reaction?

Back

A catabolic reaction is a metabolic process that breaks down larger molecules into smaller ones, releasing energy.

Front

What is an anabolic reaction?

Back

An anabolic reaction is a metabolic process that builds larger molecules from smaller ones, requiring energy.

Front

What is the first law of thermodynamics?

Back

The first law of thermodynamics states that energy cannot be created or destroyed, only transformed from one form to another.

Front

What is the second law of thermodynamics?

Back

The second law of thermodynamics states that in any energy transfer, the total entropy of a closed system will always increase.

Front

What is an example of a physical change that increases entropy?

Back

Melting ice is an example of a physical change that increases entropy.
