|
Cell function
|
- maintains a selective barrier
- inherit and transmit genetic material
- carry out catalyzed rxns
- move whole cells and/or contents
|
|
Spontaneous synthesis of organic molecules
|
- first demonstrated by stanley miller- 1950s
- provided the basic materials from which the first living organisms arose
|
|
Phospholipids
|
Basic components of all present-day biological membranes, including the plasma membranes of both prokaryotic and eukaryotic cells
|
|
Amphipathic molecule
|
Consist of one portion that is soluble in water and another portion that is not
|
|
Hydrophobic
|
(water-insoluble) - hydrocarbon chains form the inside layer of phospholipids molecules
|
|
Hydrophilic
|
(water-loving) - head groups containing phosphate form the outside layer of phospholipids molecules
|
|
Adenosine 5' triphosphate
|
(ATP) - one source of metabolic energy for all cells
|
|
Glycolysis
|
The anaerobic breakdown of glucose to lactic acid
|
|
Photosynthesis
|
Allows a cell to harness energy from the sunlight
|
|
Oxidative metabolism
|
Principle source of energy for most present day cells and utilize highly reactive O2 to generate from organic molecules
|
|
Archaebacteria
|
Prevalent on the primitive, live in extreme environments - prokaryote
|
|
Eubacteria
|
Large group of organisms that live in a wide range of environment, including soil, water, and other organisms - prokaryote
|
|
Cyanobacteria
|
Largest and most complex prokaryote - derive their energy from photosynthesis
|
|
E.coli
|
Prokaryote-rigid cell wall , plasma membrane ,DNA a circular molecule that resides in nucleoid,ribosomes
|
|
Eukaryote cells
|
Has many membranous enclose organelles, nucleus is the largest, contains most of the genetic materials, DNA molecules,
|
