This slide is all about energy transfer. It explains the role if ATP (Adenosine triphosphate), ATP Synthase, ADP (Adenosine diphosphate and Hydrogen Ion Pumps in Energy Tansfer.

1. Energy Transfer
Group 1

2. Forms of Energy
• Heat
• Light
• Motion

3. EnergyTransfer
in cells, chemical energy is gradually
released and accepted in a series of
chemical reactions that are assisted
by enzymes.

4. ATP
(Adenosine
triphosphate)
 can be used to power chemical
reactions, such as those that build
molecules.
 is a portable form of energy "currency"
inside cells
 can be "earned" or made in one place
and spent or used in another place
 made up of a chain of three phosphate
groups
 energy is released in 3rd phosphate
group is broken producing adenosine
diphosphate or ADPFormula: 𝐶10 𝐻16 𝑁5 𝑂13 𝑃3

5. ATP
(Adenosine
triphosphate)
Can be used:
to contract a muscle cell to actively
transport proteins
to help make more ATP
Formula: 𝐶10 𝐻16 𝑁5 𝑂13 𝑃3

6. ATP
(Adenosine
triphosphate)

7. ATP Synthase
an enzyme that catalyzes the
synthesis of ATP by bounding a third
phosphate group to the molecule
both an enzyme and a carrier
protein for hydrogen (𝐻+ ) ions
the flow 𝐻+ ions through ATP
synthase powers the production of
ATP

8. Oxidative
Phosphorylation
a process that oxidizes nutrients to
form ATP

9. 2 regions of
ATP Synthase
Thylakoid Membrane
Mitochondrial
Membrane

10. ATP Synthase

11. ADP
Adenosine
diphosphate
Formula: 𝐶10 𝐻15 𝑁5 𝑂10 𝑃2

12. Hydrogen Ion
Pumps
 particles of a substance diffuse through a
membrane from a region of higher concentration to
a region of lower concentration
 the inner mitochondrial membrane allows 𝐻+
ions to
diffuse through only ATP synthase
 when glucose is broken down during cellular
respiration, 𝑁𝐴𝐷+ (nicotinamide adenine
dinucleotide) accepts electrons and hydrogen
ions, which changes 𝑁𝐴𝐷+ to NADH

13. Hydrogen Ion
Pumps

14. Oxidation/Reduction
Process
 Oxidation - the adding of oxygen (O) or
Hydrogen (H) or loses electron
 Reduction - the removing of oxygen (O) or
Hydrogen (H) or gains electron

15. Oxidation/Reduction
Process
 a series of chemical reactions moves electron's between
molecules the transfer of electrons releases stored energy
that can be used to attach inorganic phosphate to ADP to
form ATP
 two simultaneous reactions or pairing
 the reactant donates electron to another reactant
 the electron donor becomes oxidized as it loses electrons
 the other reactant, the electron accepts, becomes
reduced as it gains the electron

16. Oxidation/Reduction
Process
