Organisms are energy ____________

• equalizers

• transformers

• destroyers

• 
  creators

Organisms are an example of a(n)

• 
  open system

• isolated system

• binary system

• closed system

Select all of the choices that the following statement describes: pathways that synthesize large molecules from smaller subunits

• anabolic

• endergonic

• spontaneous

• exergonic

• non-spontaneous

What is feedback inhibition?

• Feedback inhibition is when a metabolic pathway is inhibited from providing feedback to other pathways

• Feedback inhibition is when the reaction’s product functions to regulate its own further production

• Feedback inhibition is when the second enzyme in a series remains permanently blocked

• Feedback inhibition is when the first enzyme in a metabolic pathway is promoted beyond the capacity of the pathway to handle it

Even spontaneous reactions (catabolic) require activation energy to occur.

• True

• False

What is thermodynamics?

• objects in motion

• stored energy able to do work later

• the study of energy transfer

Endergonic reactions take place slowly and exergonic reactions take place quickly

• True

• False

What is the 1st law of thermodynamics?

• the study of energy transfer

• during every energy transfer, some energy becomes unusable

• energy can neither be created nor destroyed

What is kinetic energy?

• a measure of randomness, or disorder

• objects in motion

• stored energy able to do work later

What is entropy?

• a measure of randomness, or disorder

• the study of energy transfer

• stored energy able to do work later
