cellular respiration Flashcards
what is the goal
cells need energy
main equation is…
C 6 H 12 O 6 + 6 O 2 –> 6 CO 2 + 6 H 2 O + 38ATP
what are the two forms of energy
60% heat to maintain temp
40% ATP
what does ATP stand for
Adenine tri phosphate
what does ADP stand for
adenine di phosphate
how does ATP become adp
When one phosphate group is removed by breaking a phosphoanhydride bond in a process called hydrolysis, energy is released
how does adp become atp
glucose from food releases energy and a phosphate
what is the first anearobic process
glycolysis
where does glycolysis occur
cytosol
how many atp relased in glycolis
2
what is the equationfor glycolisis
GLUCOSE -> pyruvate + 2 atp
whats the next anearobic process
fermentation
what is the equation for ferfmentation
pyruvate-> pyruvic acid + lactic acid
where does the lactic acid go
the bloodstream carries it to the liver to be converted back into glucose
what is the name of the first aerobic process
kreb cycle/ citric acid cycle
what must happen. 3 steps
- oxygen present
- carbon dioxide removed
- co enzyme A is added
where is kreb at this time
mitochondria the powerhouse of the cell
how much ATP produced
2
whats the equationfor krehb
acetyl CoA -> CO2 + 2ATP+ high energy electrons
what is the last aerobic process called
electron trasnport system
where is the ETS
mitochondria
how many atp produced
34
equation ETS
high energy electrons + o2 -> 34 ATP + H2O
