Draw Glycolysis. Put OK in the blank.

What is entropy?

• the amount of order found in reactions
• when a reaction takes place and causes disorder
• heat that is released from a reaction taking place
• none of the above

A man is sitting on top of a hill. He raises his left arm in the air and waves. What type of energy is this?

• potential
• thermal
• kinetic
• chemical

A man who is sitting on a hill and raises his left arm and waves. After this, he sits still again. What type of energy is this?

• potential
• kinetic
• thermal
• chemical

What type of energy is found ATP and where is it found?

• kinetic; bonds
• chemical; third phosphate group
• kinetic; third phosphate group
• chemical; bonds

A football player is moving during a play and then sits still. He continues moving during the play and sits still, again. What is happening inside the body?

• heat is being released due to converting energy
• entropy is increasing inside the body
• enzymes are not producing enough ATP
• none of the above

Which of the following describes an exergonic reaction?

• a nonspontaneous reaction in which energy is needed for the reaction to take place
• a spontaneous reaction which needs energy to allow for the reaction to take place
• a nonspontaneous reaction in which no energy is needed to start the reaction
• a spontaneous reaction that happens without the input of energy

Which of the following describes an endergonic reaction?

• a nonspontaneous reaction in which energy is needed for the reaction to take place
• a spontaneous reaction which needs energy to allow for the reaction to take place
• a nonspontaneous reaction in which no energy is needed to start the reaction
• a spontaneous reaction that happens without the input of energy

The body needs to make more of a certain molecule. There is too much substrate and not enough enzyme. What would be the best option?

• heat up the body in order to denature the enzyme
• heat up the body in order to lower activation energy
• add more enzyme for the substrate to bind to
• regulate the genes so that way the molecule can be made

Stomach enzymes in the acid are being evaluated in a lab and are put in basic solution. What will happen to these enzymes?

• the enzymes will be denatured
• the enzymes will need large amounts of heat to work
• the enzyme will not function properly
• the active site will go through a conformational change
