Energy and Life
Energy is the ability to do workForms: light, heat, and electricity. Can be
stored in chemical compounds.ATP= adenosine triphosphate
Basic energy source for all cellsADP= adenosine diphosphate
Only two phosphate groups, stores energy
Uses
Active transport (protein pumps)Synthesis of proteinsResponses to chemical signals
Heterotrophs and Autotrophs
Heterotrophs- obtain food by consuming other living things
Autotrophs- obtain food by making their own. Photosynthesis- convertlight energy into chemical energy
Chlorophyll
Pigments- light-absorbing moleculesChlorophyll- pigment in plant
Absorb light in the blue-violet and red regions Reflect green light- that’s why they look green
Chloroplasts
Chloroplasts- place where photosynthesis takes place
Thylakoids- saclike membrane, inside chloroplasts, arranged in stacks= grana
Electrons
Light energy absorbed by chlorophyll, transferred to electrons
Overview of photosynthesis
Reaction: 6CO2 + 6H2O C6H12O6 + 6O2
Carbon dioxide plus water, light- yields sugar and oxygen
Light-dependent reaction
First set of reactions- require direct involvement of light and light-absorbing pigments
Uses energy from the sun to produce ATP Takes place in the thylakoid Water required as source of electrons and H ions.
Oxygen released as byproduct
Light-independent reaction
ATP and NADPH molecules produced in the light reaction are used to produce sugars from CO2 absorbed from the atmosphere Takes place in the stroma, liquid outside the thylakoid
