ATP/LIGHT/DARK ENERGY. Flashcards
What is ATP? A …
ATP IS ALSO…
ATP IS AN IMPORTANT MOLECULE FOUND IN ALL LIVING THINGS.
STORED ENERGY
ATP BREAKS TO
ADP AND P
ADP = ___ + ____ = ____
ADP + P + ATP
What does the cell do when it has EXTRA ENERGY?
It stores that ENERGY by reattaching a
free PHROSTATE MOLECULE TO ADP
turning it BACK into ATP.
THINK! ATP is like a rechargeable battery why?
When its fully charged its
When its run down its
WHEN ITS FULLY CHARGED its ATP
WHEN ITS RUN DOWN its ADP
THE LIGHT STAGE is also known as ____ and is path way ___ of the ______
Dependent stage.
PATHWAY 1
CYCLIC ELECTRON TRANSPORT
Remember LIGHT comes from
SUN
STEP ONE Think : 🌱 ☀️⚡️⚡️⚡️
CHLOROPHYLL ABSORBS LIGHT ENERGY.
STEP TWO. Think : 🔋💡🌱
ELECTRONS BECOME ENERGISED IN THE CHLOROPHYLL
STEP THREE. Think : 💡 passed where?
THESE ELECTRONS ARE NOW PASSED TO AN ACCEPTOR MOLECULE.
STEP FOUR. Think : ⛓️⛓️
(E-) PASSED ALONG AN ELECTRON TRANSPORT CHAIN.
ELECTRON TRANSPORT CHAIN.
STEP FIVE Think : 🤚🏽 ⚡️⚡️⚡️
THEY RELEASE THEIR ENERGY AS THE PASS ALONG
STEP SIX think: ⚡️⚡️ + ADP
Release of this energy from the energised electrons COMBINES with ADP in the cell
STEP SEVEN think: LOW 🔙
Low energy electrons go back to chlorophyll
PATHWAY 2 is called the
NON CYCLIC ELECTRON TRANSPORT
The first two steps from pathway 1 are used in Non-cyclic electron transport.
What are they?
- chlorophyll ABSORBS light energy
- electrons becomes energised in chlorophyll
PATHWAY 2 : BUT ONLY _____ get passed to the ______
ONLY TWO ELECTRONS GET PASSED TO ACCEPTOR MOLECULE.
Pathway 2 STEP 4 : What happens to water?
Water is split.
Pathway 2 STEP 4 : Water is split into
H20 = HYDROGEN OXYGEN AND ELECTRONS.
Hydrogen and two energised electrons and NADPH+ MAKE
NADPH
Step 6 and 7 of Pathway 2 :
Oxygen is released
Electrons from water restore in the chlorophyll.
3 PRODUCTS IN TOTAL OF THE LIGHT STAGE ARE
ATP
NADPH
OXYGEN
ATP Is used in
NADPH Is used in
OXYGEN is used in
ATP PATHWAY ONE cyclic E transport
NADPH PATHWAY TWO non cyclic E transport
OXYGEN released or used in respiration by plant.
ATP IS NEEDED FOR USE IN
DARK STAGE
NADPH NEEDED FOR USE IN
DARK STAGE
CO2 WE NEED TO USE BECAUSE IT MAKES
GLUCOSE
…So how are they used to make GLUCOSE
Formula of Glucose?
C6 H12 O6
ATP
stores and transfers energy to dark stage.
breaks down adp+p
the energy helps make GLUCOSE
NADPH
stores and transfers HYDROGEN IONS and ELECTRONS to dark stage.
breaks down NADPH
ELECTRONS and HYDROGEN are used to make GLUCOSE
CO2
used to make glucose by giving over carbon and oxygen to make it.
