Living EnvironmentTransport and life in

a cell

By- Justin Ehrenpreis

Page 2: Chemistry Of  Life

Active Transport-

*Lower to higher concentration

* Makes energy

Passive Transport-

*Higher to Lower concentration

*Diffusion

* No energy required

Page 3: Chemistry Of  Life

Diffusion of water through a membrane is….

osmosis

Page 4: Chemistry Of  Life

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

Page 5: Chemistry Of  Life

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

Page 6: Chemistry Of  Life

The basic unit of building blocks are….

Monosaccharide

Page 7: Chemistry Of  Life

Monosaccharide

Simple sugar

Example-

Glucose

Page 8: Chemistry Of  Life

Disaccharide-Double sugar

Dehydration Synthesis-

Process where 2 compounds combine and water removed from it

Page 9: Chemistry Of  Life

PolysaccharidesMany compounds

Page 10: Chemistry Of  Life

Lipids-

Store energy in living things

• Contain Carbon, Hydrogen, and Oxygen

• greater than 2:1

*Examples- *Fatty acids and glycerol

Fats + oils = Lipids

Page 11: Chemistry Of  Life

Pinocytosis

-cell drinking-dissolves molecules

Page 12: Chemistry Of  Life

Phagocytosis

cell eatingLike Pac man

Page 13: Chemistry Of  Life

Proteins• Carbon, Hydrogen ,Oxygen and Nitrogen

Amino Acids-

Building blocks of proteins

2 amino acids =

Dipeptide + Water

Page 14: Chemistry Of  Life

Nucleic Acids• Composed of…

nucleotide chains

That has…

genetic information.

Nucleic acids are found in…

Living cells and viruses

Page 15: Chemistry Of  Life

Summary• Carbohydrates

• Ch2

• Monosaccharides

• Lipids

• 1 Glycerol + 3 Fatty Acids

• Proteins

• Symbol is N

• Amino Acids

• R represents…

Any group

Page 16: Chemistry Of  Life

What do compounds look like?

• Has 6 sides

• Looks like a Hexagon

• Some times without any lines
