Chapters 1-8 (Supposedly
Perfect ratio for surface are and volume
Cell extracts energe and creates an external product from the chemical reaction
Rate of division
When a cell decides to make a copy of itself, how fast does it occur?
Rate of division in human cells.
25 x 10
Growth Curve Equation
Stages of growth curve
n in growth curve
hours/ division rate
Growth curve with very little/ no lag
Thermodynamically working at maximum speed
Growth curve with long/ slow lag
Process for virus
Protein finds a recpetor
Virus is received or denited
Virus is copied by cell upon entrance
Exits out to envirnment
Can exist outside a cell and influences the process.
Exists in cell and influences the product and cell.
Subclinical stage of growth rate
Four criteria to establish causual relationship between microbe and disease
1) isolate organism from person
2) identify the isolated organism
3) test on a healthy animale
4) repeat to determine if organism is indeed a pathogen
Fundamental pieces of cell
If the receptor on a potential host is a proteind then it invites the virus protein in.
Shapes looking for each other
Treatment for Viruses
attempt to hide the receptor so the virus can't find its 'match'
Enzymes in virus
more effective enzymes result in rapid cell copying
1) Antogens- place on slide and wait for chemical reactions
4 billion years ago
Cytoplast is work central
Very durable cell wall
2 Billion years ago
specialized subunit within a eucaryotic cell with a specific function
usually separately enclosed within its own lipid bilayer
Current O2 levels in atmosphere
metabolic pathway that converts glucose C6H12O6, into pyruvate, CH3COCOO− + H+.
The free energy released in this process forms the high-energy compounds ATP (adenosine triphosphate)
Most primative cell
glucose in ---> lactate out
Potential free energy in glucose
Freed energy from glycolisis

Enzymes in metabolic state
Invagination in membrane
increases surface area and allows the cells to work easier
Cannot have more volume than SA to move goods in and out
extension from cell
Lipids and Gram Stain
Lipids = Gram Negative

death of cells
Microbiology studies/ encompasses
Technology that allows the deliberate altering if DNA
functions in attachment to other cells as receptors
Delineates two different groups of bacteria
Looks like an open faced sandwich
3 layer sandwich
key intersection in several metabolic pathways.
output of the anaerobic metabolism of glucose known as glycolysis
