Introduction to Metabolism Flashcards
What is Kinetic Energy?
Energy of motion
What is Metabolism equal to?
Catabolism + Anabolism
What are some examples of Kinetic Energy?
- Heat
- Light
- Electrical
- Mechanical
What does Anabolic mean?
Through synthesis.
What does Catabolic mean?
Through destruction
Define Potential Energy.
The energy of position; stored energy.
Define Chemical Energy.
Potential energy stored as bonds.
Define the First law of Thermodynamics.
The Conservation of Energy - Energy can be transferred and transformed but never created or destroyed.
Define the Second Law of Thermodynamics.
- Energy transformations lead to an increase in entropy/disorder.
- Not all energy can be used to do work.
- Often released as heat.
What is Free Energy (dG)?
The Free Energy to do work.
dG = dH - TdS
What does ATP stand for?
Adenosine Triphosphate
What does Thermodynamics do?
Tells whether or not a reaction is spontaneous.
What are competitive inhibitors?
Cofactors that compete with substrate for the same active site.
What are Noncompetitive Inhibitors?
Cofactors that bind to an allosteric site and changes the shape to prevent binding of a substrate.
What is Feedback inhibition?
The idea that if an early step is shut down, all the following activities are shut down.
