Cellular Respiration Flashcards
Structure of ATP
3 phosphate groups, ribose, adenine
Structure of ADP
2 phosphate groups, ribose, adenine
ATP Cycle
ATP releases energy from food and ends up with ADP and P
When energy from food enters ADP and P, ATP is created
Chemical Equation for Cellular Respiration
C6H12O6 + 6O2 = 38 ATP + 6H2O + 6CO2
Reactants of cellular respiration
glucose and oxygen
Where does glucose (reactant of cellular respiration) come from?
the food we eat; from carbohydrates broken down, absorbed into bloodstream and delivered to the cells through the circulatory system
Where does oxygen (reactant of cellular respiration) come from?
the air we breathe; breathe into lungs, to bloodstream and delivered to cells by the circulatory system
Products of Cellular Respiration
ATP, carbon dioxide, water
Where does ATP (product of cellular respiration) go?
used by cells in all processes that require energy
Where does carbon dioxide (product of cellular respiration) go?
breathe it out; delivered to the lungs through the bloodstream by the circulatory system
Where does water (product of cellular respiration) go?
used in cells, breathe it out or release with urine
Three Stages of Cellular Respiration
glycolysis, Kreb’s Cycle, electron transport chain
Where does glycolysis occur?
cytoplasm
Where does the Kreb’s Cycle occur?
mitochondrial matrix
Where does the electron transport chain occur?
inner membrane of the mitochondria
(inner mitochondrial membrane)
