|
feedback inhibition
|
the control mechanism used by cells to stop and start metabolic pathways
|
|
|
ATP synthase
|
is the enzyme that helps make ATP molecules in the last stage of cellular respiration
|
|
|
lactic acid
|
is the name of the product of anaerobic fermentation that can accumulate in muscle tissues and make them sore
|
|
|
NADH and FADH
|
are the two electron carriers that help move electrons through cellular fermentation
|
|
|
Redox reactions
|
involve the chemical transfer of electrons
|
|
|
acetic acid
|
is the sharp-smelling product of the breakdown of pyruvic acid
|
|
|
acetyl CoA
|
acetic acid becomes this before it can be carried into the mitochondria
|
|
|
ATP
|
this is the goal of cellular respiration
|
|
|
oxidation
|
is the process a chemical undergoes to lose electrons
|
|
|
the Krebs cycle
|
Cells produce ATP, NADH, and FADH during this cycle
|
|
|
ethyl alcohol
|
this is a liquid produced during anaerobic fermenttaion used during the bread-making process.
|
|
|
electron transport chain
|
is the final stage of cellular respiration
|
|
|
glycolosis
|
is the breakdown of glucose into two molucules of pyruvic acid.
|
|
|
aerobic reaction
|
is a reaction that requires oxygen.
|
|
|
fermentation
|
is used for energy when some cell can't get oxygen for cellular respiration
|
|
|
FADH
|
is an electron-carrying molecule
|
|
|
pyruvic acid
|
is the results of a split in a glucose molecule
|
|
|
reduction
|
is a reaction in which electrons are gained
|
|
|
coenzyme A
|
helps acetic aid cross the membrane f the mitochondria
|
|
|
oxidation
|
is a reaction in which electrons are lost
|
|
|
What are the three stages of cellular respiration?
|
The first stage is glycolysis in which glucose is broken down into smaller molecules of pyruvic acid. In the Krebs cycle, electron carriers are generated. During the electron transport chain, the electron carriers use the electrons to make ATP
|
|
|
How can bacteria that live in mud carry out cellular respiration?
|
They can't get oxygen so they use anaerobic methods.
|
|
|
Where in your body would you expect to find cells that have a lot of mitochondria? Explain.
|
Mitochondria are organelles associated with production of energy, so all cells have them. However, cells that produce large amounts of energy have more. Two fo teh places where mitochondria are dense are the muscle cells fo the thigh and in aardia cells.
