1.2 - Basic Metabolism Flashcards
The three categories of life on earth
- Plants (make own food)
- Fungi (external digestion)
- Animalia (internal digestion)
In order to acquire Internal digestion we need
a nervous system to move and senses to perceive the world
Six critical life processes for humans
- Metabolism (energy/homeostasis)
- Responsiveness (energy/homeostasis)
- Movement (energy/homeostasis)
- Growth (cellular organization)
- Differentiation (cellular organization)
- Reproduction
Metabolism is
The sum of all chemical reactions in the body
Glucose + O2 -> CO2 + H20 is a what reaction
Catabolic reaction
Catabolic reaction is where
A complicated molecule broken down to simpler
Anabolic reactions entail
Combining of monomers into polymers (simple into complex) (building)
First Law of Thermodynamics
Energy cannot be created or destroyed but can change forms
Second Law of Thermodynamics
Spontaneously everything goes towards entropy (disorder/chaos/lack of order)
Complexity or anabolism requires
Input of energy
Breaking apart or simplifying complex structures will
Release stored energy
Anabolic reactions require input of energy so they are ________.
Endergonic
Catabolic reactions have a release of energy so they are ____.
Exergonic
Most organized form of energy is
Light (in the form of photons from the sun)
Light to sugar for plants is a
Anabolic/endergonic rxn
