WGU Biochemistry OA 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) 1 / 4
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 2 / 4
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 3 / 4
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
