Chapter 7: Cellular Respiration Flashcards
Cellular Respiration
Glucose + oxygen CO2 + water + ATP
Cellular Respiration Equation
C6H12O6 + O2 —> CO2 + H2O + 36 ATP
Glycolysis
takes place in the cytoplasm: Glucose (6 carbons) broken down into two molecules of pyruvate (3 carbons
Pyruvate
three-carbon sugar that can be decarboxylated and oxidized to make acetyl CoA, which enters the citric acid cycle under aerobic conditions; the end product of glycolysis.
Fermentation
when oxygen is not present (anaerobic breakdown of glucose into lactic acid or ethanol).
Citric- Acid Cycle
(Kreb’s Cycle) in matrix of mitochondria : NAD+ → NADH and FAD → FADH2 (About 38 ATPs total produced).
ATP Synthesis
membrane-embedded protein complex that adds a phosphate to ADP with energy from protons diffusing through it.
Electron Transport Chain
How is breathing related to aerobic cellular respiration?
What organisms perform aerobic cellular respiration?
What is ATP and why is it essential to life?
ATP is energy and it is essential to life because it is needed in many essential processes.
What are the three processes of Cellular Respiration?
