Micro quiz chapter 7

Exergonic reactions

• release energy, making it available for cellular work

• are driven forward with the addition of energy

Endergonic reactions

• are driven forward with the addition of energy

• release energy, making it available for cellular work

releases energy by oxidation of molecules

• anabolism

• catabolism

uses energy to synthesize macromolecules that makeup the cell

• Anabolism

• catabolism

oxidation

• loss of electrons

• gain of electrons

reduction

• loss of electrons

• gain of electrons

Oxidoreductases:

• an electron donor and an electron acceptor involved in a redox reaction

• •The cell does not handle electrons as separate entities but rather as parts of an atom such as hydrogen, which contains a proton and an electron

• enzymes that remove electrons from one substrate and add them to another

• catabolic pathways provide the energy infusion that generates the high-energy phosphate to form ATP

break down ATP 3p

• catabolic

• anabolic

build ATP 2p

• catbolic

• anabolic

removal of hydrogens from a compound during a redox reaction

• Aerobic respiration

• Fermentation

• Dehydrogenation

• glycolysis
