ENERGY IN A CELL

AUTOTROPHS – USE ENERGY TO MAKE THEIR OWN FOOD – EXAMPLES INCLUDE… PLANTS, GREEN ALGAE, AND SOME BACTERIA AUTOTROPHS – USE ENERGY TO MAKE THEIR OWN FOOD – EXAMPLES INCLUDE… PLANTS, GREEN ALGAE, AND SOME BACTERIA HETEROTROPHS – OBTAIN ENERGY FROM THE FOOD THEY CONSUME – EXAMPLES INCLUDE… HERBIVORES OMNIVORES CARNIVORES DETRITIVORES DECOMPOSERS HETEROTROPHS – OBTAIN ENERGY FROM THE FOOD THEY CONSUME – EXAMPLES INCLUDE… HERBIVORES OMNIVORES CARNIVORES DETRITIVORES DECOMPOSERS

When ATP is used, it loses a phosphate group and becomes ADP. There is still potential energy in the remaining two bonds. If the cell does not need more energy immediately, it will add a phosphate group to the ADP, which becomes ATP. ATP  ADP + + ENERGY

A PROCESS THAT CONVERTS SOLAR ENERGY INTO CHEMICAL ENERGY BY MAKING GLUCOSE

PHOTOSYNTHESIS ACTUALLY OCCURS IN 2 AREAS... IN THE THYLAKOIDS (DISCS) AND IN THE STROMA (GEL)

* REMEMBER: L IGHT DEPENDENT REACTIONS OCCUR IN THE THYLAKOIDS ( ON THE LEFT IN THIS PIC ) & THE LIGHT INDEPENDENT REACTIONS (C ALVIN CYCLE ) OCCUR IN THE STROMA ( ON THE RIGHT )

A PROCESS THAT CONVERTS FOOD (GLUCOSE) INTO CHEMICAL ENERGY BY MAKING ATP

CELLULAR RESPIRATION ACTUALLY OCCURS IN 2 AREAS... CYTOPLASM (for glycolysis and fermentation) & MITOCHONDRIA (for Kreb’s Cycle and the ETC)

O2O2 H2H2 H2OH2O

O2O2 H2H2 H2OH2O PRODUCES… -LACTIC ACID OR ETHANOL
