CELL RESPIRATION Flashcards
4 metabolic stages of Cellular respiration
Anaerobic respiration
Aerobic Respiration
Pyruvate oxidation
Krebs cycle
Electron Transport Chain
Anaerobic respiration that occurs in cytosol
Glycolysis
- Respiration using O2
- occurs in mitochondria
Aerobic Respiration
- respiration without O2
- occurs in cytosol
Anaerobic Respiration
Organisms in the bottom of the ocean utilizes _________ to produce energy
Sulfur
- Step-by-step breakdown of high-energy glucose molecules to release energy
- Takes place day and night in all living cells
- Occurs in stages controlled by enzymes
Cellular respiration
Breakdown of Cellular respiration
Glycolysis
Grooming phase
Krebs Cycle
Electron Transport Chain and Oxidative Phosphorylation
- splitting of sugar.
- occurs in cytosol, just outside of mitochondria
Glycolysis
migration from cytosol to matrix.
Grooming phase
mitochondrial matrix
Krebs Cycle (Citric Acid Cycle)
- Also called Chemiosmosis
- occurs in the inner mitochondrial membrane.
Electron Transport Chain (ETC)
and Oxidative Phosphorylation
Energy Currency of cells
ATP
contains potential energy, much like a compressed spring.
ATP
When a phosphate group is pulled away
during a chemical reaction
Energy is released
This cycle is the fundamental mode of energy exchange in biological systems.
ATP-ADP Cycle
