Cellular Respiration

Front 1

cellular respiration

Back 1

first stage glucose is broken down to pyruvate second stage the presence of oxygen determines whether aerobic respiration or anaerobic process will occur

Front 2

glycolysis

Back 2

1- phosphate groups from two ATP molecules are transferred to a glucose molecule
2-the resulting six-carbon compound is broken down to two three-carbon compounds each with a phosphate group
3- two NADH molecules are produced and one more phosphate group is transferred to each three-carbon compounds
4- each three-carbon compound is converted to a three-carbon pyruvate,producing four ATP molecules in the process

Front 3

Krebs Cycle

Back 3

1- acetyl-CoA combines with four-carbon compound, forming a six-carbon compound and releasing coenzyme A
2- carbon dioxide is released from the six-carbon compound, forming a five-carbon compound. electrons are transferred to NAD+ making a molecule of NADH
3- carbon dioxide is released from the five-carbon compound forming a four-carbin compound
4- the five-carbon compound is converted to a new four-carbon compound
5- the new four-carbin compound is converted to the four-carbon compound that began the cycle

Hint 3

main second stage

Front 4

electron transport chain of aerobic respiration

Back 4

1- the electron transport chain pumps hydrogen ions out of the inner compartment
2- At the end of the chain electrons and hydrogen ions combine with oxygen forming water
3- ATP is produced as hydrogen ions diffuse into the inner compartment through a channel
