Cellular Respiration Flashcards
cellular respiration is a coupled
reaction with ATP synthesis
cellular respiration involves breaking down
glucose
during cellular respiration, glucose is oxidized
slowly
cellular respiration begins with
glycolysis
glycolysis is the
breakdown of glucose
glycolysis occurs in the
cytoplasm
glycolysis reactants
glucose, 2 NAD+, 2ADP+P
glycolysis products
2 pyruvates, 2 ATP, 2 NADH
two types of cellular respiration are
aerobic and anaerobic respiration
aerobic respiration occurs
in the presence of oxygen
link reaction creates
acetyl CoA
the krebs cycle releases
2 ATP
The Electron Transport Chain is located
in the inner membrance of the mitochondria
proteins pump H+ ions
against the concentration gradient
H+ ions naturally diffuse
back to low concentration
as H+ ions diffuse, they cross the membrane at
ATP synthase
ATP synthase is turned
by H+ ions crossing and synthesizes ATP
the ETC creates 30
-34 ATP
anaerobic respiration occurs
without oxygen
two types of fermentation are
alcoholic and lactic acid
products of alcoholic fermentation
ethanol + C02
alcoholic fermentation can be found in beer,
wine and bread
alcoholic fermentatin is done by
yeast, bacteria
Is alcoholic fermentation reversible?
No, and it can be fatal
products of lactic acid fermentation
3C + lactic acid
lactic acid fermentation is found in
cheese, animals, and fungi
Is lactic acid fermentation a reversible process?
Yes
What do both lactic acid and alcoholic fermentation have in common?
NADH is converted back to NAD+
Occur without oxygen
Happen after glycolysis
Do not create ATP
