o What did they do
Test next Monday.
Robert Hooke (1665) made a piece of concave glass that allowed him to magnify things.
He realized that there are things smaller than the eye can see.
Discovered this from looking at cork.
Named it cell because it looked like w
Carbon Compounds and Life
Organic Chemisty - the study of compounds containing carbon.
Aside from water, living organisms consist of carbon-based compounds.
Stuff that is not made by a living thing.
Made by a livin
Metabolism- All of an organism's chemical reactions.
Metabolic Pathway- Things have to go in certain steps, there is no skipping allowed.
Enzymes- Speed up a reaction.
Catabolic Pathway Energy is made
Cellular respiration is an example

Introduction (escience lab 5) Growth of Microorganisms
In previous labs, you explored the abundance of microorganisms that co-exist with us (in or on
our bodies and surrounding environment) by growing them on media that provided the

Metabolism- totality of an organisms chemical reaction
A metabolic pathway starts when a molecule is changed in a series of
defined steps, then, produces a specific product; each step is catalyzed by a
Cellular Respiration and Fermentation
Catabolic Pathways yield energy by oxidizing organic fuels
o Several processes are central to cellular respiration and related pathways
o The breakdown of organic molecules is exergonic
o Fermentation is a partial de
Bombardier Beetle They have two pouches that when mixed, cause a redox reaction.
Reaction causes gas and boiling hot liquid.
Matter- Anything that takes up space.
Matter exists in 92 different elements.

How do catabolic pathways yield energy?
Transfer of stored electrons in organic molecules
Release of energy
Energy is used to synthesize ATP
When electrons move, energy moves, and this makes ATP
4 types of macromolecules
50% of the dry mass (means mass minus water) of most cells is protein.
Such as keratin.

Water & Carbon
Importance of Water
70-80% of the body is water.
Polar covalent bonds (unequal sharing), ends with an electronegative molecule. It makes a polar molecule.
Water is a polar molecule because it has electronegative qualities.
Photosynthesis takes inorganic molecules and turns them into organic molecules.
Takes place in the chloroplasts.
Waste products are organic molecules and O2.
The following perform photosynthesis:
Lipid layer goes around the outside of the cell.
Selective Permeability- When the phospholipid bilayer decides what gets in and leaves the through the cell wall.
Phospholipids are the most abundant lipid in the membrane.
It is a
