Flashcards in Metabolism Deck (15):
1

Metabolism

Flow of Energy
-the capacity to do work
--work-movement, transport, or making things

2

What general forms is Energy found in?

-Kinetic
-Potential

3

Kinetic Energy

Energy of movement/ motion
-light, heat, electrical

4

Potential Energy

Stored Energy
-Chemical bonds (in living things)

5

Laws of Thermodynamics

1. Law of Conservation
2. Law of Entropy

6

Law of Conservation

Energy cannot be created of destroyed
-Changes forms

7

Law of Entropy

Disorder will increase
-As energy changes forms more energy is changed to forms we cannot use.

8

Anabolic Reaction

Putting something together, making something bigger
-Endergonic

9

Catabolic Reaction

Breaking something down
-Exergonic
--not spontaneous

10

Reaction Coupling

An exergonic reaction powering an endergonic reaction.

11

Endergonic

Requires energy

12

Exergonic

Gives off energy

13

Energy measurement

Heat is measured to measure the energy of something.
- Calorie is the unit of energy measurement
-The amount of heat it takes to raise 1gram water from 14.5C to 15.5C (1 degree Celsius)
-Calorie= 1,000 calories or Kcal= 1kg water raised 1 degree Celsius.

14

Energy of Activation

Needed to get the reaction going

15

Types of Chemical reactions

Anabolic Reaction
Catabolic Reaction
