9.1 Chemical Pathways

glycolysis purpose

turns glucose (6 carbon) into pyruvate (3 carbon)

glycolysis input

glucose and 2 ATP

glycolysis output

4 ATP, 2 pyruvate, and 2 NADH

only reaction of mitochondria that is aerobic

ETS (electron transport chain)

kreb's cycle input

Acetyl CoA

where does glycolysis happen

cytoplasm

where does kreb cycle happen

mitochondrial matrix

where is the mitochondrial matrix

the big space thing surrounded by the inner membrane of the mitochondria

how many membranes does mitochondria have

2

what is space between the two membranes of mitochondria called

intermembrane space

kreb cycle output

6CO2 (byproduct), 2ATP, 8NADH, 2FADH2

electron transport chain input

10 NADH, 2 FADH2, 6 O2

electron transport chain output

32 ATP and H2O

where does electron transport chain happen

inner membrane space (cristae)

ATP yield of one NADH

2.5 ATP

ATP yield of one FADH2

1.5 ATP

how much net ATP is made from glycolysis

2

how much net ATP is made from Krebs

2

how much net ATP is made from kreb's

around 28

step one of cellular respiration

glycolysis

step two of cellular respiration

krebs

step three of cellular respiration

electron transport chain (ETS)

acetyl coa (acetyl coenzyme)

pyruvate is turned into this for use in kreb's

fermentation

release energy as ATP from food without oxygen

alcoholic fermentation equation

pyruvic acid + NADH = alcohol + Co2 + NAD+

lactic acid fermentation

pyruvic acid + NADH = lactic acid + NAD+

where is lactic acid produced

in your muscles

feeling of lactic acid

"sour" in your muscles

grocery items of fermentation

alcohol and bread

what cells perform lactic acid fermentation

muscle cells and unicellular organisms
