WorksheetsCB6 Glycolysis Review
Total questions: 16
Worksheet time: 8mins
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
Where does NAD+ go after itś regenerated?
mitochondria
cytoplasm
glycolysis
aerobic respiration
what happens after glycolysis?
goes into aerobic respiration if oxygen is present and anaerobic if not
glycolysis starts over again
ATP from glycolysis begins to help begin photosynthesis
nothing
what is NAD+?
glucose
full electron carrier
3 carbon molecule
empty electron carrier
what contributes to soreness of muscles?
alcohol fermentation
lactic acid fermentation
aerobic respiration
glycolysis
Glycolysis is the second stage of cellular respiration.
True

False
After the NAD+ receives electrons, what does it change to?
ATP
