glucose O2O2 CO 2 plants animals, plants ATP The Great Circle of
Life,Mufasa! CO 2 H2OH2O C 6 H 12 O 6 O2O2 light energy +++ even
though this equation is a bit of a lie it makes a better story CO 2
H2OH2O C 6 H 12 O 6 O2O2 ATP energy + + +
ATP ATP is biological energy ATP + water ADP + P = energy When
you break the bond you get energy ATP = stored energy ADP = used
Cellular Respiration Process that releases energy by breaking
down glucose and other food molecules in the presence of oxygen.
6CO 2 6H 2 O C 6 H 12 O 6 6O 2 ATP energy + + + Glucose 38 ATP
Cytoplasm 2 ATP needed 4 ATP produced 2 ATP produced 34 ATP
produced Oxygen required If no oxygen is present then fermentation
occurs CO 2 released
Glycolysis (occurs in cytoplasm) Break down glucose into 2
pyruvate molecules Glucose has 6 carbon Pyruvate has 3 carbon No
oxygen in required (anaerobic) Needs 2ATP to happen Generates 4ATP
Net gain of 2ATP at the end of the process
After Glycolysis If oxygen is present, pyruvate moves to
mitochondria where cellular respiration occurs. If not oxygen is
present, pyruvate is used for alcoholic or lactic acid
Cellular respiration occurs in two steps Krebs cycle or citric
acid cycle Produced 2ATP Electron transport chain Produced 34 ATP
Both processes require oxygen and occur in the mitochondria
Krebs cycle Pyruvic acid produced from glycolysis is used to
make Carbon dioxide NADH ATP FADH 2 4 ATP are produced for
immediate use for cell processes NADH and FADH 2 carry electrons to
the electron transport chain to make more energy CO 2 is released
from the cell
Electron transport chain The ETC used high energy electrons
from the Krebs cycle to convert ADP to ATP. ETC is composed of a
series of carrier proteins in the inner membrane of the
mitochondria. Water is produced and released at the end of the ETC.
34 ATP are produced in the end
Fermentation Two types Alcoholic fermentation Lactic acid
fermentation Both processes do not require oxygen (anaerobic) and
occur after glycolysis.
Alcoholic fermentation Yeasts and a few other microorganisms
use this process CO 2 bubbles that are released from this process
cause bread to rise. Also used to make beer and wine
Lactic acid fermentation Occurs in humans and other eukaryotes
Muscle cramps are caused by a build up of lactic acid When you
exercise vigorously, the large muscles run out of oxygen quickly.
Your muscles quickly produce ATP using lactic acid fermentation.
Lactic acid builds up which causes your muscles to ache.
