DEF OF ENERGY
THE CAPACITY TO DO WORK.

2 FORMS, KINETIC AND POTENTIAL.
LAWS THAT GOVERN THE CONVERSION OF ENERGY
THE TWO LAWS OF THERMODYNAMICS
1 LAW OF THERMODYNAMICS
ENERGY IS NEITHER CREATED NOR DESTROYED
2 LAW OF THERMODYNAMICS
CONVERSION OF ENERGY IS NOT 100% EFFICIENT
ENDERGONIC VS EXOGERNIC ENERGY
INPUT OF ENERGY VS OUTPUT OF ENERGY
CELLULAR RESPIRATION
EXERGONIC AND RELEASES ENERGY BY THE BREAKDOWN OF GLUCOSE
CELLULAR METABOLISM
ALL THE ENDERGONIC AND EXERGONIC REACTIONS IN CELLS
ADENISUBE TRIPHOSPHATE MOLECULES
ATP MOLECULES POWER NEARLY ALL FORMS OF WORK
ATP AND ADP IN PHOSPHOHORYLATION
ENERGY FROM EXERGONIC REACTIONS IS STORED IN ATP.

ATP BECOMES ADP IN A PROCESS CALLED PHOSPHOHORYLATION.

ENERGY IS RELEASED BY THE HYDROLYSIS OF THE PHOSPHATE GROUP AND WORK IS PERFORMED
ENZYMES
PROTEINS THAT REDUCE THE AMOUNT OF ENERGY NECESSARY FOR REACTIONS TO OCCURE.

HAVE SPECIFIC SHAPES THAT FACILITATE CERTAIN REACTIONS
INHIBITORS
BLOCK ENZYME ACTIVITY

SOME PESTICIDES AND ANTIBIOTICS
MEMBRANES IN CELLS
ACT LIKE ASSEMBLY LINES FOR ORGANIZING REACTIONS
PLASMA MEMBRANES
SELECTIVE IN THE TYPE OF MOLECULES THEY ALLOW IN OR OUT
PHOSPHOLIPID BILAYER
PROTEIN MOLECULES ARE EMBEDDED IN LAYER TO MAKE THE PLASMA MEMBRANE A MOSAIC OF STRUCTURE AND FUNCTION
SIGNAL TRANSDUCTION
MESSAGES WITHIN A CELL TO PERFORM A SPECIFIC ACTIVITY
PASSIVE TRANSPORT
DIFFUSION: SMALL MOLECULES MOVING ACROSS THE MEMBRANE PASSIVELY FROM AN AREA OF HIGH CONCENTRATION TO LOW

AKA OSMOSIS
HYP-ER-TONIC VS HYP-O-TONIC
HYPER: SOLUTION WITH HIGHER CONCENTRATION

HYPO: SOLUTION WITH LOWER CONCENTRATION
WATER BALANCE BETWEEN CELLS AND ENVIORNMENT
CRITICAL

EX: RED BLOOD CELLS IN SOLUTION W/ NO IONS WILL SHRIVEL

MAINTAINING PROPER BALANCE IS CALLED OSMOREGULATION
FACILITATED DIFFUSION
TRANSPORT PROTEINS HELP MOVE SOME MOLECULES ACROSS PLASMA MEMBRANE
ACTIVE TRANSPORT
USES ENERGY TO MOVE MOLECULES ACROSS THE MEMBRANE AGAINST THE CONCENTRATION GRADIENT

(REQUIRES ENERGY WHERAS DIFFUSION DOESN'T)
EXOCYTOSIS
MOVES BULKY MOLECULES OUT OF CELLS
EXOCYTOSIS

ENDOCYTOSIS
EXO: MOVES BULKY MOLECULES OUT OF CELLS

ENDO: MOVES BULKY MOLECULES IN
CHLOROPLASTS
USE ENERGY FROM SUNLIGHT TO COMBINE WATER AND CARBON DIOXIDE TO MAKE SUGARS
