The ability to do work or

bring about a change

•ENERGY

•Food is specifically called _________________ energy, because energy is stored in its bonds.

•Chemical Energy

Looking at the picture of Max on a slide, indicate where you would find kinetic and potential energy

•Potential-On top of the slide•Kinetic-Once Max goes down the slide

The boys are eating and then join a soccer game. Where would you find mechanical energy and chemical energy?

•Chemical energy is found in our food, we break it down metabolically and convert it into mechanical energy (motion)

What is the First Law of Thermodynamics?

•Energy cannot be created or destroyed, but can be changed from one form to another. (Conservation of Energy)

•The 2nd Law of Thermodynamics states that energy cannot be changed from one form to another without a loss of usable energy. •What is the “useable energy” usually released as?

•Heat

•The relative amount of disorganization is called:

•Entropy

Which room is more stable and would therefore favor the laws of entropy?

•The messy one is more stable. The clean one requires more “work” to stay clean.

•Explain the difference between endergonic and exergonic reactions

•Endergonic- require an input of energy (cold pack)•Exergonic-releases energy (explosion)

•What is the difference between anabolic and catabolic?

•Anabolic-The building up or synthesis of molecules•Catabolic-The breaking down of molecules

•What does ATP turn into after it has been hydrolyzed by water and has given off energy?

•ATP is broken down by water (hydrolysis) gives off energy and heat and turns into ADP

Describe how endergonic and exergonic reactions are “coupled” in lifting weights

•ATP breaks down to release energy (exergonic) your muscles use that energy to contract (endergonic)

List the 3 types of “work” that ATP can be used for

•Chemical work, transport work and mechanical work

Enzymes are metabolic catalysts that lower the _________________, so that the reaction can occur quicker.

•Energy of Activation, or Ea

•The change in energy of the products from the reactants is written as_________________________

•DELTA G

•An enzyme that would break down the sugar Maltose, would most likely be named:

•Maltase

What are the 6 factors affecting enzymatic speed?

• Temperature• pH• Substrate concentration• Enzyme Activation• Enzyme Inhibition• Enzyme Cofactors

When an Enzyme can no longer bind to its substrate because of exposure to high heat, we say that the enzyme has been:

•Denatured
