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