Term
metabolism 
Definition
all chemical reactions in a cell
Term
enzymes  
Definition
protiens that catalayze or speed up chemical reactions
Term
energy  
Definition
ability to do work or bring about change
Term
kinetic energy
Definition
energy of motion mechanical
Term
potential energy  
Definition
stored energy (battery)
Term
entrophy  
Definition
amount of disorganization messy-ness
Term
laws of thermodynamics
Definition

(1) matter and energy is neither created nor destroyed, but marely changes form

 

(2) when energy changes from one form to another form there is always a loss of unstable energy.

Term

organized =

disorganized = 

Definition

less stable

more stable 

Term
exergonic reaction

Adenosine triphosphate

(ATP) 

what are the advantages of adenosine triphosphate 

Definition

1. can be used in diff reactions

2. produces sufficent energy for biological reactions

3. energy loss is minimized 

Term
3 functions of ATP Adenosin Triphosphate
Definition

1. chemical

synthesis macromolecules 

2 transport

energy to pump substances across the cell membrane 

3 mechanical 

provides energy for muscle movement 

Term
advantages of metabolic pathways
Definition

1 pathway can lead to several others

energy is captures and released easily if released in small amounts

can regulate the pathways
