Energy and Life Energy is the ability to do work Forms: light, heat, and electricity. Can be stored in chemical compounds. ATP= adenosine triphosphate Basic energy source for all cells ADP= adenosine diphosphate Only two phosphate groups, stores energy

Uses Active transport (protein pumps) Synthesis of proteins Responses to chemical signals

Heterotrophs and Autotrophs Heterotrophs- obtain food by consuming other living things Autotrophs- obtain food by making their own. Photosynthesis- convert light energy into chemical energy

Chlorophyll Pigments- light-absorbing molecules Chlorophyll- 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
