biology: cellular respiration Flashcards
what is a calorie
energy need to raise 1 gram of water 1 degree Celcius
where does energy come from?
breaking down food
what is a Calorie?
a Kilocalorie, or 1000 calories
cellular respiration
also called aerobic respiration, needs oxygen
releases energy from food molecules, ie glucose to make ATP
ATP is for temporary energy storage
cellular respiration equation
6O2 + C6H12O6 = 6H2O + ENERGY
all eukaryotes _____ some eukaryotes_____
cellular respirate
photosynthesize
why is cellular respiration so complicated?
broken into smaller steps to make lots of ATP
where does glycolysis occur
in cytosol
anaerobic or aerobic, lot or little ATP
anaerobic, little
where does Krebs cycle occur
mitochondrial matrix
mitochondrial matrix
space inside inner membrane of mitocchondria
aerobic or anerobic, lots of little ATP in Krebs cycle
aerobic, lots
what is broken down in Krebs cycle, where does it come from
pyruvate from glycolysis
In Krebs cycle what is released?
2 molecules of CO2
1 ATP
3 NADH
1 FADH2
where does chemiosmosis occur
electron transprt chain in cristae of inner mitochondrial membrane
