Chapter 6 Flashcards
relationship between photosynthesis and cellular respiration
photosynthesis uses E from the sun to rearrange CO2 and H20 into glucose and O2
cellular respiration breaks down glucose in the presence of O2 to release E in ATP and releases CO2 and H2O
equation for cellular respiration
6O2 + C6H12O6 -> 6CO2 + 6H2O + ATP
redox reaction
Movement of e- from one molecule to another
Oxidation - loss of electrons
Reduction - gaining of electrons
in cellular respiration, identify the reactant that is oxidized
oxidized - glucose lose electrons from hydrogen atoms
in cellular respiration, identify the reactant that is reduced
reduced - O2 gains electrons from hydrogen atoms
identify and summarize the three stages of cell respiration
Glycolysis - occurs in the cytoplasm, turns 1 glucose into 2 pyruvates, 2 ATP, 2 NADH
Krebs cycle - occurs in the matrix, turns 2 pyruvates into 6CO2, 2 ATP, 6 NADH, 2 FADH2
Electron transport chain - occurs in the inner membrane of the Mitochondria, turns 6O2, 8 NADH, 2 FADH2 into 34 ATP, 6H2O
identify the reactants of glycolysis
glucose, 2 ATP, 2 NAD+
identify the products of glycolysis.
2 pyruvates, 2 ATP, 2 NADH
substrate-level phosphorylation
an enzyme transfers a phosphate group from an organic molecule to ADP, a small amount of ATP is produced
