, Bohr Effect chart (low pH) C- High CO2
H- High H+
A- Acidic
R-Release of O2(rt. Shift)
T- tense state (in tissues)
Primary structure Sequence of amino acids that make up a protein
Secondary Structure Sequence of amino acids fold.
Tertiary Structure -more folding in a 3D shape.
-R groups (side chains)
Quaternary Structure Protein has more than 1 polypeptide chain.
Chemical reaction -absorb and release energy
-activation energy
-energy is released (heat & light) when bonds are broken.
Exothermic reaction Exo=to release
Thermo=heat
-chemical reaction that releases more energy than it absorbs (as heat & light)
Example of exothermic reaction Cellular respiration- breaks down glucose to make cellular energy
Endothermic reaction Endo=absorb
Thermos=heat
-absorbs more energy than it releases
Example of endothermic reaction Photosynthesis- takes in light to break down to create glucose
Catalyst Substance that will decrease the activation energy needed to start a chemical
reaction
Enzymes -catalysts used by cells
-increase the rate of chemical reaction
-specific to substrates
Enzyme structure -they are proteins
-twist, fold, bend to final shape
-shape attracts specific molecules
Substrate Molecules that bind to the enzyme
Active site -location on enzyme where substrate binds
Function of DNA polymerase in process of PCR. -increase expression
-2 genes
-SIRT1 & SIRT2
