|
the three different pathways that meet and enter into TCA cycle
|
carbohydrates, proteins, and fats
|
|
|
the break down of glucose to energy starts with what?
|
glycolysis to pyruvate
|
|
|
when glycolysis starts to break down to pyruvate what might could happen?
|
it may be converted to lactic acid
|
|
|
what happens in the last stage of the breaking down glucose to energy?
|
all the energy yielding nutrients enter the TCA cycle or Kreb's cycle and the electron transport chain

anarobic
|
|
|
requires oxygen

a 2 carbon structure
|
acetyl CoA
|
|
|
which can be used to make glucose?
Pyruvate or Acetyl CoA |
pyruvate
|
|
|
a series of metabolic reactions that break down molecules of acetyl CoA to carbon dioxide and hydrogen atoms
|
TCA cycle
|
|
|
the final pathway in energy metabolism that transports electrons from hydrogen to oxygen and captures the energy released in the bonds of ATP
|
electron transport chain
|
|
|
the energy powerhouse of the cell
|
mitochondria
|
|
|
a 3 carbon compound produced from pyruvate during anaerobic metabolism
|
lactate
|
|
|
a path for lactate that transports from the muscles to the liver. there the liver can convert the lactate produced in muscles to glucose, which can then be returned to the muscles.
|
Cori cycle
|
|
|

deamination
|
|
|
needs nutrients but no food available
|
starvation
|
|
|
choosing to not eat
|
fasting
|
