Pre-Lesson Concepts

Question 1

The sum of chemical reactions that take place in living cells to sustain life.

Answer 1

Metabolism

Question 2

If metabolism is required for life, then it should be important for what?

Answer 2

Obtaining of Biomolecules (Macromolecules):

Proteins
Fats
Carbohydrates
Nucleic Acids

Question 3

Our body doesn’t necessarily match the macromolecules what we intake with food, so…

Answer 3

It is digested and broken down into the component parts of each biomolecule.

Question 4

Component Part of Protein

Answer 4

Amino Acid

Question 5

Component Part of Fats

Answer 5

Fatty Acids

Question 6

Component Part of Carbs

Answer 6

Glucose (Sugar)

Question 7

Component Part of Nucleic Acids

Answer 7

Nucleotides

Question 8

How does breaking these biomolecules down help us at all?

Answer 8

Well, it needs to be realized that while it is broken down into its monomers, the products are taken and built back up.

Question 9

Two Types of Metabolism

Answer 9

Catabolism and Anabolism

Question 10

The process of the breakdown of complex molecules into numerous simple ones.

Answer 10

Catabolism

Question 11

The process of the building of complex molecules from numerous simple ones.

Answer 11

Anabolism

Question 12

A fun way to remember both is that:

C for Catabolism: ___
A for Anabolism: ___

Answer 12

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.

Question 13

With anabolism involving the synthesis of biomolecules, it needs energy, but from where?

Answer 13

ATP

Question 14

A simple analysis of molecules (in terms of energy) would be:

Breaking up of Bonds: ___energy
Synthesis: ___ energy

Answer 14

Breaking up of Bonds: Releases energy
Synthesis: Requires energy

Question 15

Since catabolism “cuts”, it ___ energy to transform ADP to ATP.

Answer 15

Releases

Question 16

Since catabolism “adds”, it ___energy to transform ATP to ADP.

Answer 16

uses

Question 17

Anabolism or Catabolism?

Photosynthesis

Answer 17

Anabolism

(Producing of Glucose and Water)

Question 18

Anabolism or Catabolism?

Cellular Respiration

Answer 18

Catabolism

(Glucose is broken down to Usable energy)

Question 19

Catabolism ___ Anabolism

Answer 19

Fuels

(It is coupled, relies on one another)

Question 20

1st Law of Thermodynamics

Answer 20

Law of Conservation of Energy

Question 21

2nd Law of Thermodynamics

Answer 21

Entropy

Question 22

What does the Law of Conservation of Energy state?

Answer 22

Energy isn’t created nor destroyed.

Question 23

What does the second law of thermodynamics state?

Answer 23

The second law states that any spontaneous (not requiring an outside source of energy to proceed) process increases the disorders of the universe.

Question 24

What, Why, When, How, and Who is Entropy (S)?

Answer 24

A thermodynamic quantity that expresses the degree of disorder in a system.

Question 25

What is Enthalpy (H)?

Answer 25

The loss or gain of heat in chemical reactions.

Question 26

What is Gibbs Free Energy?

Answer 26

The amount of energy in a system that is available to do useful work.

And with this energy, it determines how spontaneous a reaction is.
