Metabolism
Chemistry
-
-
Matter- occupies space, has mass
elements are unique forms, that can't be broken down any further
Isoptopes- forms of an element with different numbers of neutrons, so different mass number
-
Bohr Model- early model with protons in nucleus and electrons in circular orbits at specific distances.
-
-
Microbial Metabolism
-
Enzymes- most end in -ase, lower the energy of activation, proteins
Temperature, pH, substrate concentration, and inhibitors all affect it. Denaturation- is a permanent change in the structure of a protein
Carbohydrate Catabolism
the breakdown of carbohydrate molecules to produce energy, two ways to produce energy
Glycolysis- the first step in carbohydrate catabolism, occurs in the cytoplasm, concretion of one molecule to two of pyretic acid
-
Fermentation
Does not require oxygen, is not very efficient in ATP production, produces NAD and NADP
Biological Molecules
Carbohydrates- Carbon, hydrogen and oxygen atoms
-
Can be mono, di, or poly saccharides
-
-
Lipids- compose of carbon, hydrogen and oxygen, non-polar, function as energy storage and structure
Saturated- no carbon to carbon bonds, said, lard, butter
unsaturated- one or more carbon double bonds, liquid, vegetable sources
Trans fats- more resemble saturated, contribute to atherosclerosis more
Proteins- made of carbon, hyrdogen, oxygen and nitrogen, make up most of cells weight, also make amino acids
Primary- polypeptide chain, second- occurs when chain folds and coils in regular helix, tertiary- 3 dimensional shape, quaternary- consists of 2 or more polypeptides
Nucleic acids
DNA and RNA, each contains a nitrogenous base, a 5 carbon sugars and a phosphate group
DNA- double strand, deoxyribose, thymine
RNA- singel strand, ribose, uracilm rRNA, mRNA, tRNA
