when cells break down food moleucels energy
is temproarily stored in atp molecuels
atp
is essential for a cell to perform all the tasks necessary for life
a substance produced during phtosynthesis that is used for completeion of cellular respiration is
oxygen
the process of cellular respiration
breaks down food molecuels to release stored energy
cellular respiration: organic compounds::
automobile:gasoline
when glycolysis occurs
glucose split
2 molecules pyruvic acid made
some atp is produced
the name of hte process that takes place when organic compounds are broken down in the absence of oxygen is
fermentation
when muscles are exercised extensively in the absence of sufficient oxygen
lactic acid is produced
cellular respiration takes place in two stages
glycolysis, then aerobic respiration
in cellular respiration a two carbon molecuel compines with a four carbon molecule to form citric acid is part of
krebs cycle
acetyl coenzyme a
enters krebs cycle
can be used in synthesis of needed molecules
is from the breakdown of pyruvic acid
clycolysis and aerobic respiration are different in that
glycolysis occurs in the absence of oxygen while aerobic respiration requires oxygen
which of the following is not formed during the krebs cycle
NADPH
which of the following is no part of cellular respiration
calvin cycle
whith oxygen present the krebs cycle and hte elctron transport chain
provide organisms and alternative to glycolysis
produces most of the atp needed for life
break down all glucose to produce carbon dioxide water and atp
water is an end product in
electron transport chain
krebs cycle: co2::;
electron transport chaing: ATP
atp molecules produced during aerobic respiration
enter the cells cytoplasm through the membranes of the motochondria in which they are formed
at the end of the electron transport chain
the electrons combine wiht oxygen and protons to form water
when living cells break down molecules energy is
stored as atp
stored as adp
releasedl asl heat
in cellular respiration th emost energy is transferred during
electron transport chain
electrons are donated to the electron transport chain by
atp and nadh
____is a biochemical pathway of cellular respiration that is anaerobic
glycolosis
glucose is split into smaller molecuels during a biochemical pathway called
glycolysis
in the absence of oxygen, glycolysis is followed by _____instead of aerobic respiration
fermentation
during fermentation either ethyl alcohol and carbon dioxide ro_____is formed
lactic acid
the krebs cycle takes place in the ______
mitochondrial matrix
