oxidation-reduction (redox) reactions ~ a reaction that involves the transfer of electrons between reactants, many involve the reaction of a substance with oxygen oxidation ~ loss of electrons reduction ~ gain of electrons OIL RIG ~ oxidation is loss, reduction is gain redox reactions are those in which the following occurs: ~ -a substance reacts with elemental oxygen -a metal reacts with a nonmetal -one substance transfers electrons to another substance combustion reactions...

BIO 100 EXAM 2 LATEST VERSION GRADED A+ LECTURE#6 Cell Communication **What is the role of the plasma membrane in a cell?** The plasma membrane acts as the "gatekeeper" of the cell, separating it from its environment and regulating the passage of molecules. It is composed of a hydrophobic phospholipid bilayer that allows small and hydrophobic molecules to pass through. **What are concentration gradients in cellular context?** Concentration gradients refer to the differences in...

EAPS Exam 3 Study Guide Questions and answers, rated A+ Characteristic of fire - -- Fire is an exothermic (heat producing), self-perpetuating,chemical reaction initiated by a small amount of heat. - The process causes fuels to be combined with oxygenleading to new compounds, a lot more heat, and light The fire tetrahedron - -Heat - Produced during combustion because the reaction is exothermic. Since these reactions are ongoing, combustion releases more than enough heat to make the fir...
