Fermentation and Glycolysis

Glycolysis equation

• 2 CO2 + 2 NAD+ -> 2 ATP + 2 NADH

• Glucose + 2 ATP + 2 NAD+ -> 2 Pyruvic acids + 4 ATP + 2 NADH

• Glucose + 2 H2O + NAD+ -> 2 Pyruvic acids + 4 ATP + 2 NADP+

• none of the above

Difference between Aerobic and Anaerobic respiration?

• they need different energy sources

• aerobic uses oxygen unlike anaerobic

• anaerobic does not go through fermentation

• aerobic respiration is associated with alcohol fermentation

Why would an organism go through fermentation if we get 0 ATP from this process?

• because it produces glucose

• to produce pyruvic acids

• to regenerate NAD+

• because it makes the cell grow

where is aerobic and anaerobic respiration located?

• aerobic: cytoplasm

  anaerobic: stroma

• aerobic: mitochondria

  anaerobic: stoma

• aerobic: chlorophyll

  anaerobic: cytoplasm

• aerobic: mitochondria

  anaerobic: cytoplasm

alcohol fermentation equation

• 2 pyruvic acids + 2ATP → ethanol + CO₂ + NAD+

• 6CO₂ + 6H₂O → C₆H₁₂O₆ + 6O₂

• Glucose + 2ADP +2NAD+ → Pyruvic acid + 2 ATP +2NADH

• C6H12O6 + 6O2 → 6CO2 + 6H2O

lactic acid fermentation equation

• C6H12O6 + 6O2 → 6CO2 + 6H2O

• C6H12O6 → 2C3H6O3

• 2 pyruvic acids + 2ATP → Lactic acid + NAD+

• C6H12O6 + 2 ADP + 2 [P]i + 2 NAD+ → 2 pyruvate + 2 ATP + 2 NADH

example of who uses alcohol fermentation

• yeast

• mitochondria

• animal muscle

• fungus

how much ATP is required to start glycolysis?

• 1

• 3

• 4

• 2

How do all living organisms obtain energy?

• cellular respiration

• photosynthesis

• mitosis

• calvin cycle

Where does NAD+ go after itś regenerated?

• mitochondria

• cytoplasm

• glycolysis

• aerobic respiration
