- Fermentation is...
- when cells convert NADH into NAD+ allowing glycolysis to proceed
- Glycolysis
- First step in cellular repiration. Breaks down glucose into pyruvic acid
- 1 Food Calorie =
- 1000 calories, 1 kilo calorie
- Lactic Acid Fermentation
- (animals) (also) regenerates NAD+ so glycolysis can continue. pyurvic acid + NADH = lacitc acid + NAD+
- Formation of Acetyl CoA
- pyurvic acid enters the mitochondrion, one carbon is lost to CO2, NAD+ - NADH, coenzyme A joins with the remaning 2 carbons
- When O2 (oxygen) is NOT present the process is termed
- anaerobic
- 6 NADH's form ___ in Krebs Cycle
- 2 FADH
- The Krebs Cycle occurs when oxygen (is/is not) present
- is
- Fermentation Occurs When Oxygen (is/is not) present
- not
- For every 1 Glucose ___ Acetyls are made
- 2
- Two Phases of Glycolysis
- 1. Energy investement phase - 2 ATP's are invested to supply the activation E. 2 Energy payoff phase - 4 ATP's and 2 NADH's are produced
- Glycolysis will shuts down without
- NAD+
- Cellular Respiration Formula
- 6O2 + C6H12O6 --> 6C02 + 6H2O + Energy
- Alcohol Fermentation
- (plants) following glycolysis, when oxygen is not present in PLANT cells. pyurvic acid + NADH = alcohol + CO2 + NAD+
- Krebs Cycle
- 2-C Acetyl CoA, NAD+ - NADH, NAD+ - NADH, ADP - ATP, NAD+ - NADH, FAD - FADH, repeats
- Glycolysis Process
- 6 carbon glucose, 2NAD+ - 2NADH, 2ADP - ATP, = 2 3 carbon pyruvic acids
- When O2 (oxygen) IS present the process is termed
- aerobic
- Glycolysis is energized by
- ATP
- Goal of Fermentation
- to regenerate NAD+
- Calorie is...
- amount of heat required to raise 1g of water 1* C
