|
what is the first stage of cell respiration
|
Glycosis
|
|
|
what dose glycosis do
|
enzymes partially oxyidize gluecose and split it into 2,
3-carbon molecules |
|
|
what is the second stage of cell respiration
|
the krebs cycle
|
|
|
what dose the krebs cycle do
|
completes the decomposition and oxidation of gluecose to carbon dioxide
|
|
|
what is the third stage of cell respitation
|
the electron transport system
|
|
|
what are cytochromes
|
they are protiens that are embbedded in the inner membrane of the mitochondria
|
|
|
what is fermantation
|
it occurs without oxyegen and is less efficient that cell respiration
|
|
|
what is the difference between aerobic and anerobic reespiration
|
aerobic respiration occurs in the presense of oxyegen and anerobic respiration occurs without oxygen
|
|
|
what is cell respiration
|
a decompisiton pathway that provides the energy that cells need to fuction
|
|
|
how many ATP doescell rispiration produce
|
38 ATP
|
|
|
during what process is pyrivic acid formed
|
glycosis
|
|
|
what are the 3 hydrogen carriers
|
NADH,NADPH,andFADH2
|
|
|
when dose water come into play in cell respiration
|
the electrontransport system
|
|
|
what is the function of water in the electrom transport system
|
at the end of the electron transport system hydrogen carried by NDAH and FADH2 bond with oxygen to form water. the energy released in this reaction is used to synthesize ATP
|
|
|
what are facultative aerobes
|
organisms that can survive with or without oxygen
|
|
|
what are obligate anerobes
|
organisms that survive entierly on fermen tation aka anerobic respiration
|
|
|
what are obligate aerobes
|
organisms that cant survive long without oxygen
|
|
|
what is hydrolisis
|
the breaking of bonds by inserting a water molecule
|
|
|
what is brown fat
|
used to quickly produce thermal energy and raise body temperatures to normal
|
|
|
what is coenzymeA (CoA) adn in what process nis it found
|
it is a carrier molecule founnd in the krobs cycle
|
|
|
one gram of gluecose = how many calories
|
3811 calories
|
|
|
what is a calorie
|
the amount of energy needed to heat one gram of energy needed to heat one gram of water one degree
|
|
|
what is the chemichal ezuation of cell respiration (and photosynthesis in reverse)
|
6 O2 + C6 H2 O6 = 6 CO2 + 6 H2O + energy
|
|
|
how many ATP molecules are needed to start the reaction
|
2 ATP
|
|
|
how many ATP are produced from the krebs cycle
|
4 ATP, but since 2 ATP are needed to start the reaction ther is a net gain of 2 ATP
|
|
|
what does lactic fermentation produce
|
oxygen and energy
|
|
|
what does alchohol fermentation produce
|
alcohol and CO2
|
|
|
i what process is citric acid found
|
electron transport system
|
|
|
what dose the electron transport system produce
|
32 ATP (net gain)
|
|
|
how does the electron transport system work
|
it uses molecules from the krobs cycle to turn ADP into ATP
|
