Living EnvironmentTransport and life in
a cell
By- Justin Ehrenpreis
Active Transport-
*Lower to higher concentration
* Makes energy
Passive Transport-
*Higher to Lower concentration
*Diffusion
* No energy required
Diffusion of water through a membrane is….
osmosis
Organic Compounds-
*contain Hydrogen and Carbon
*4 major compounds are…
1- Carbohydrates
2- Lipids (fats)
3- Proteins
4- Nucleic Acids
• Inorganic Compounds-
• Lack Carbon and Hydrogen combination
Examples-
1- Water
2- Salts
Carbohydrates-* main source of
energy for all cell activities
• Made of Carbon, Hydrogen, and Oxygen
• CH2• Includes Starches
and sugars
• Three types of Carbohydrates-
1- Monosaccharide
2- Disaccharide
3- Polysaccharide
The basic unit of building blocks are….
Monosaccharide
Monosaccharide
Simple sugar
Example-
Glucose
Disaccharide-Double sugar
Dehydration Synthesis-
Process where 2 compounds combine and water removed from it
PolysaccharidesMany compounds
Lipids-
Store energy in living things
• Contain Carbon, Hydrogen, and Oxygen
• greater than 2:1
*Examples- *Fatty acids and glycerol
Fats + oils = Lipids
Pinocytosis
-cell drinking-dissolves molecules
Phagocytosis
cell eatingLike Pac man
Proteins• Carbon, Hydrogen ,Oxygen and Nitrogen
Amino Acids-
Building blocks of proteins
2 amino acids =
Dipeptide + Water
Nucleic Acids• Composed of…
nucleotide chains
That has…
genetic information.
Nucleic acids are found in…
Living cells and viruses
Summary• Carbohydrates
• Ch2
• Monosaccharides
• Lipids
• 1 Glycerol + 3 Fatty Acids
• Proteins
• Symbol is N
• Amino Acids
• R represents…
Any group
What do compounds look like?
• Has 6 sides
• Looks like a Hexagon
• Some times without any lines
