Pre-Lesson Concepts Flashcards
The sum of chemical reactions that take place in living cells to sustain life.
Metabolism
If metabolism is required for life, then it should be important for what?
Obtaining of Biomolecules (Macromolecules):
Proteins
Fats
Carbohydrates
Nucleic Acids
Our body doesn’t necessarily match the macromolecules what we intake with food, so…
It is digested and broken down into the component parts of each biomolecule.
Component Part of Protein
Amino Acid
Component Part of Fats
Fatty Acids
Component Part of Carbs
Glucose (Sugar)
Component Part of Nucleic Acids
Nucleotides
How does breaking these biomolecules down help us at all?
Well, it needs to be realized that while it is broken down into its monomers, the products are taken and built back up.
Two Types of Metabolism
Catabolism and Anabolism
The process of the breakdown of complex molecules into numerous simple ones.
Catabolism
The process of the building of complex molecules from numerous simple ones.
Anabolism
A fun way to remember both is that:
C for Catabolism: ___
A for Anabolism: ___
Well, fuck me, here we go again with these silly ass analogies.
C is for Cut, Catabolism in short.
A is for Add, Anabolism in short.
With anabolism involving the synthesis of biomolecules, it needs energy, but from where?
ATP
A simple analysis of molecules (in terms of energy) would be:
Breaking up of Bonds: ___energy
Synthesis: ___ energy
Breaking up of Bonds: Releases energy
Synthesis: Requires energy
Since catabolism “cuts”, it ___ energy to transform ADP to ATP.
Releases
Since catabolism “adds”, it ___energy to transform ATP to ADP.
uses
Anabolism or Catabolism?
Photosynthesis
Anabolism
(Producing of Glucose and Water)
Anabolism or Catabolism?
Cellular Respiration
Catabolism
(Glucose is broken down to Usable energy)
Catabolism ___ Anabolism
Fuels
(It is coupled, relies on one another)
1st Law of Thermodynamics
Law of Conservation of Energy
2nd Law of Thermodynamics
Entropy
What does the Law of Conservation of Energy state?
Energy isn’t created nor destroyed.
What does the second law of thermodynamics state?
The second law states that any spontaneous (not requiring an outside source of energy to proceed) process increases the disorders of the universe.
What, Why, When, How, and Who is Entropy (S)?
A thermodynamic quantity that expresses the degree of disorder in a system.
