Releasing Energy from Foods
What is the function of photosynthesis?
Energy storage Converts light energy to chemical energy in the form of glucose.
What are the two stages of
photosynthesis?
Light CalvinReactions Cycle
requires light
light independent
What is the formula for glucose?C6H12O6
Where in the cell does photosynthesis take place?Thylakoid membranes of chloroplasts.
Where in the chloroplast does the Calvin cycle take place?
Grana of chloroplast
What is the equation for Photosynthesis?
6CO2 + 6H2O → C6H12O6 + 6O2
What are the reactants of Photosynthesis?
CO2 and H2O
What are the products of Photosynthesis?
C6H12O6 and O2
What is the function of Cellular
Respiration?
Energy release Breaks down glucose to form ATP for cellular activities
Cellular Respiration
Glycolysis (yields ATP)
Aerobic Anaerobic(oxygen) (w/o oxygen)
fermentation
Yields 21- 36 Yields 2 ATPATP
Anaerobic Respiration
Alcohol Lactic AcidFermentation Fermentation
Alcohol & CO2 Lactic acid + CO2
baking, sours milk,
brewing muscle fatigue
What is glycolysis and where does it take place?
Glycolysis breaks down glucose into pyruvic acid in the cytoplasm
How many molecules of ATP does glycolysis produce?
2 molecules of ATP
How many molecules of ATP does Cellular Respiration produce?Glycolysis 2 ATPAerobic + 36 ATPTotal 38 ATP
Where in the cell does Cellular Respiration take place?Mitochondria – 2 membrane (outer and inner folds cristae)
Energy Release/Storage CycleATP= Adenosine Tri Phosphate (A-P-P-P)
ADP = Adenosine Di Phospate (A-P-P)
A-P-P - P energy energystorage release
A-P-P + P
What is the equation for Cellular Respiration?
C6H12O6 + 6O2 → 6CO2 + 6H2O (+ Energy in
form of ATP)
What are the reactants of Cellular Respiration?C6H12O6 and O2
What are the products of Cellular Respiration?CO2 and H2O
