6.3 How is cell energy transported within cells?
- transportation of energy in cells
- glucose is the energy provider,
energy from glucose is transferred
to energy carrier-molecules
- energy carrier-molecules are high-energy
molecules that are synthesized at the
site for an exergonic reaction
- like rechargeable batteries
- like rechargeable batteries
- energy carrier-molecules only transfer
and capture energy within cells
- glucose is the energy provider,
energy from glucose is transferred
to energy carrier-molecules
- ATP and electron carriers
transport energy within cells
- ATP adenosine triphosphate is the
most common energy-carrier molecule
in the body is produced during the
breaking down of exergonic reactions
- called "energy
currency" of cells
- most ATP is produced in the
mitochondria. Mitochondria is known
as the power house of the cell
- not a long-term energy-storage
molecule: life time in cell is short;
it's recycled about 1,400 times a day
- called "energy
currency" of cells
- ADP adenosine diphosphate
- ADP to ATP,
endergonic reaction
- ADP to ATP,
endergonic reaction
- electron carriers
- capture energetic
electrons along with
hydrogen ions (H+)
- energetic electrons gain the energy from
exergonic reactions, in which glucose breakdown
and sun capturing in photosynthesis happen
- energetic electrons gain the energy from
exergonic reactions, in which glucose breakdown
and sun capturing in photosynthesis happen
- carries energy and transfers
their high energy electrons
to other molecules to form
ATP, NADPH, FADH2
- capture energetic
electrons along with
hydrogen ions (H+)
- ATP adenosine triphosphate is the
most common energy-carrier molecule
in the body is produced during the
breaking down of exergonic reactions
- coupled reactions link exergonic
with endergonic reactions
- coupled reaction
- an exergonic reaction provides the energy
needed to drive an endergonic reaction using
ATP electron carriers as intermediates
- ATP are a must because exergonic
and endergonic reactions occur in
different places within a cell
- ATP are a must because exergonic
and endergonic reactions occur in
different places within a cell
- energy is lost as
heat in this process
of transformation
- Energy released by exergonic reactions
must exceed the energy needed to
drive the endergonic reaction
- Energy released by exergonic reactions
must exceed the energy needed to
drive the endergonic reaction
- an exergonic reaction provides the energy
needed to drive an endergonic reaction using
ATP electron carriers as intermediates
- coupled reaction
