ATP
• ATP(Adenosine triphosphate)- a high-energy
molecule that stores and supplies cells with
needed energy.
CHEMICAL BOND
• An attraction between two atoms
resulting from a redistribution of their
outer electrons.
• Covalent Bond : Sharing of on or more
pairs of e-
CHEMICAL ENERGY
• Chemical Energy - energy stored in the
bonds of chemical compounds, released in a
chemical reaction, often producing heat.
• Batteries, biomass, petroleum, natural gas,
and coal are examples of stored chemical
energy.
CHLOROPHYLL
• A green pigment, in green plants,
that absorbs light to provide energy
for photosynthesis.
CHLOROPLAST
• (In green plant cells) the cell part
that contains chlorophyll and
where photosynthesis takes
place.
LIGHT DEPENDENT
REACTIONS
• In photosynthesis, the reactions
that convert sunlight to ATP on
the thylakoid membranes
.
LIGHT INDEPENDENT
REACTIONS
• - reactions that convert CO2 and other
compounds into glucose in the stroma.
• stroma, the fluid-filled area of a chloroplast
outside of the thylakoid membranes.
PHOTOSYNTHESIS
• - using sunlight to synthesize foods from
carbon dioxide and water.
• Photosynthesis in plants generally involves
the green pigment chlorophyll and generates
oxygen as a by product.
PHOTOSYNTHESIS EQUATION
TROPHIC LEVEL
• The position an organism occupies in a food
chain.
