Glycolysis Flashcards
Glycolysis happens in the
Cytoplasm
GLYCOLYSIS also known as
• EMBDEN-MEYERHOF PATHWAY
A pathway for carbohydrate catabolism that begins with the substrate D-glucose
Glycolysis
Glycolysis is aerobic or anaerobic
Anaerobic
Three Major Products of Glycolysis
ATP - chemical energy
nADH - chemical energy
2 three-carbon pyruvate
Six-Carbon Stage of Glycolysis
(Steps I - 3)
Three-Carbon Stage of Glycolysis
(Steps 4 - 10)
Steps in glycolysis the consumed energy
Steps 1 & 3
Steps in glycolysis that makes ATP
Steps 7 & 10
Energy consuming stage
Steps 1-3

Entry point for galactose in glycolysis
Glucose 6 phosphate

Dihydroxyacetone phosphate
Glyceraldehyde
THREE COMMON FATES OF PYRUVATE
(ALE)
Acetyl CoA
Lactate
Ethanol
- is the enzyma9c anaerobic reduc9on of pyruvate to lactate
- The sole purpose of this process is the conversion of NADH to NAD
Lactate fermentation
Working muscles ocen produce
lactate
- is only an effective means of energy production during short, intense exercise, providing energy for a period ranging from 10 seconds to 2 minutes.
Anaerobic glycolysis
Lactic Acid Cycle also known as
Cori cycle
involves turning lactate into glucose because the body cannot use lactate for energy.
Cori cycle
Gluconeogenesis occurs in the
Liver
Glycolysis occurs in the
Muscle
- the enzymatic anaerobic conversion of pyruvate to ethanol and carbon dioxide
ETHANOL FERMENTATION
involving yeast causes bread and related products to rise as a result of CO2 bubbles being released during baking.
Ethanol fermentation
Beer, wine, and other alcoholic drinks are produced by ________ of the sugars in grain and fruit products.
ethanol fermentation
Glycolysis occurs in the
Cytoplasm
Krebs cycle occurs in the
Mitochondria
