Understanding Gibbs Free Energy

Mr. Anderson explains Gibbs Free Energy, aiming to make it more understandable, especially in biology. He discusses the concept of available energy, spontaneous reactions, and the Gibbs Free Energy equation. Examples like a ball rolling, diffusion, and a cherry bomb illustrate these concepts. The video also covers exergonic and endergonic reactions, with cellular respiration and photosynthesis as examples. Finally, the role of ATP in energy transfer is discussed, highlighting its importance in biological processes.

What is another term used for Gibbs Free Energy that might be more intuitive?

• Thermal Energy

• Kinetic Energy

• Available Energy

• Potential Energy

In a spontaneous reaction, what happens to the enthalpy of the system?

• It increases

• It remains constant

• It decreases

• It fluctuates

What does entropy measure in a system?

• The pressure

• The total energy

• The temperature

• The disorder or randomness

How does increasing temperature affect the spontaneity of a reaction?

• It has no effect

• It makes the reaction less likely

• It stops the reaction

• It makes the reaction more likely

What is the Delta G value for a spontaneous reaction?

• Equal to zero

• Less than zero

• Greater than zero

• Undefined

Which biological process is an example of an exergonic reaction?

• Cellular Respiration

• Photosynthesis

• Protein Synthesis

• DNA Replication

What is the primary energy currency of cells?

• ATP

• Glucose

• NADH

• FADH2

In photosynthesis, what is the Delta G value?

• Less than zero

• Equal to zero

• Undefined

• Greater than zero

What is required to convert ADP back into ATP?

• No energy change

• Decrease in temperature

• Absorption of energy

• Release of energy

What is the ultimate fate of energy as it is converted through biological processes?

• It is stored indefinitely

• It is converted into light

• It ends as heat

• It disappears
