what is the process in which a glucose molecule is split in half?
glycolysis
100
process that doesn't require oxygen
anaerobic
100
The pathways of the krebs cycle and electron transport make up
cellular respiration
100
what happens during the krebs cycle?
pyruvic acid is broken down into carbon dioxide in a series of energy extracting reactions
100
what does the E.T.C do
it uses high energy electrons to change ADP into ATP
200
what does glycolysis form
this forms two molecules of pyruvic acid, a 3-carbon compound
200
process that does require oxygen
aerobic
200
Cellular respiration is the process that releases energy by.....
breaking down glucose and other food molecules in the presence of oxygen
200
What is another name for the krebs cycle and why
citric acid cycle because it is one of its first products
200
what happens in the E.T.C
high energy electrons move from one carrier to another
300
where does glycolysis takes place
glycolysis takes place in the cytoplasm
300
what does fermentation do? Does it require oxygen?
it releases energy from food molecules by forming ATP. It does not require oxygen
300
what kind of process is cellular respiration
aerobic
300
When does the krebs cycle start
it starts when pyruvic acid formed by glycolysis enter the mitochondria
300
how many cells form from glucose in the E.T.C
34 ATP molecules per glucose molecule
400
what does a cell gain through glycolysis
a cell gains 2 ATP molecules through glycolysis
400
What are the two types of fermentation
alcoholic and lactic acid
400
what is the equation for cellular respiration?
oxygen+glucose goes to carbon dioxide+ water+energy
400
What happens to the cells during the Krebs cycle
NAD+ forms into NADPH and FAD forms into FADH
400
What is a calorie
an amount of energy that is needed to raise the temperature of 1 gram to 1 degree celcius
500
What is the electron carrier? what does it do?
NAD+ is the electron carrier it accepts a pair of high energy electrons producing NADPH. Also NAD+ helps pass energy from glucose to other pathways in the cell
500
during fermentation what happens to the cells?
they convert from NADPH back to NAD+
500
what does cellular respiration remove and put back?
removes oxygen and puts back carbon dioxide
500
what is release as a waste product
carbon dioxide
500
How are the energy flows of photosynthesis and cellular respiration
they are opposite
photosynthesis removes carbon dioxide and puts back oxygen
while cellular respiration removes oxygen and puts back carbon dixode
