Bio molecules
Lipids
Carbohydrates
Nucleic acids
Protein
Max size of cell is limited by what?
It’s need for enough surface area for exchange with environment
What is similar about all cells on earth
Ribosomes
What defines in\out of a cell?
Plasma membrane
What is a difference between eukaryotic and prokaryotes
Eukaryotic cells have internal membrane
“Membrane bound organelles”
Stereoisomers
Same chemical formula but different orientation
Conformation
No breaking bonds
Rotation and movement around bonds
Configuration
Covalent bonds need to be broken and changed
- geometric cis and trans (double bonds with no freedom of movement)
- chiral centres = asymmetrical carbon needs 4 different groups bonded
Chiral carbons
Non mirror images of each other.
Need to break bonds to make the same
Homeostasis
Made up of cells
Have a life cycle
Undergo metabolism grow and adapt to environment
Reproduce and evolve
Common feature of all cells
Cytoplasm
Plasma membrane
Ribosomes
