17 Cards in this Set

  • Front
  • Back
reduction
gain of electrons and become more negative
reducing agent
reduces the other molecule by becoming oxidized itself
oxidation
lose of electrons and become more positive
oxidizing agent
oxidizes other molecule by stealing electrons
redox
something is reduced, something is oxidized
redox in respiration
glucose is oxidized in respiration, oxygen is reduced
NADH
NAD+ + H+ + 2e-
FADH2
FAD + 2H
H
H+ + e-
ETC
Electrons lose a little potential energy every time they go from one carrier to the next. The carrier that receives them becomes reduced, and when it passes them, becomes oxidized. Each carrier is more electronegative than the last.
substrate level phosphorylation
phosphate is stripped directly from one molecule and bonded to an ADP to make ATP
oxidative phosphorylation
addition of a phosphate to ADP by ATP synthase as a result of ETC activity
Glycolysis
2 pyruvate, 4-2 ATP, 2NADH
acetyl co A
pyruvic acid + coenzyme A makes acetyl co A and CO2
Investment phase
2 ATP are invested in glycolysis
payoff
2 NADH per glucose molecule
2 ATP per (2) carbon sugars (4)
Krebs
1 ATP, 3 NADH and 1 FADH2 per turn (turns 2x)
