CHARACTERISTICS OF LIFE?
*MADE UP OF CELLS
*USE ENERGY TO LIVE,GROW,DEVELOP
*MAINTAIN STABLE INTERN. ENVIRON
*PASS HERDITARY INFORMATION ON
METABOLISM?

HOMEOSTASIS?
COMBINATION OF CHEMICAL REACTION

MAINTAIN INTERNAL STABLE ENVIRON
CELL RESPIRATION?

SYNTHESIS?
BREAKING NUTRIENTS DOWN TO RELEASE CHEM ENERGY STOREDINSIDE

COMBINING SIMPLE SUBSTANCES INTO COMPLEX SUBSTANCES
ALL LIVING THINGS MADE UP OF..?


ORGANIC VS. INORGANIC MOLECULES??
CHON!

CARBON
HYDROGEN
OXYGEN
NITROGEN

ORGANIC: IS MADE UP OF CARBON AND HYDROGEN
[DNA,PROTEIN,FATS,CARBS]

INORGANIC: CO2 O2 H20
ORGANIZATION OF LIVING THINGS?
CELLS-TISSUES-ORGANS-ORGAN SYSTEMS-ORGANISMS
ORGANELLES: CYTOPLASM
TRANSPORTS MATERIALS
SITE OF CHEM REACTIONS
ORGANELLES: NUCLEUS
CONTROLS CELLS METABOLISM AKA CHEM REACTIONS

STORES GENETIC INFO
DNA IN CHROMOSOMES *C BEFORE D*
ORGANELLES: VACUOLES

ORGANELLES: RIBOSOMES
CONTAIN WASTES/WATER/FOOD

IMPORTANT TO MAKE PROTEIN
ORGANELLES: MITOCHONDRIA
CONTAIN PROTEINS KNOWN AS ENZYMES.. TO GET ENERGY OUT OF NURTIENTS
ORGANELLES: CHLOROPLASTS
CONTAIN CHLOROPHYLL TO CAPTURE LIGHT ENERGY
ORGANELLES: CEL MEMBRANE
SEPARATE CELL FROM OUTSIDE
CONTROL TRANSPORT OF MATERIALS
RESPOND TO CHEM SIGNALS
DIFFUSION

PASIVE/ACTIVE TRANSPORT
MOVEMENT OF MOLECULES FROM AREAS OF HIGH CONCENTRATION TO AREAS OF LOW CONCENTRATION

ACTIVE TRANSPORT: LOW-> HIGH WHICH REQUIRES ENERGY FROM ATP
DIGESTION
LARGE MOLECULES BROKEN DOWN INTO SIMPLER MOLECULES TO ENTER CELL

EX: PROTEIN-> AMINO ACIDS
STARTCHES-> SUGARS
HUMAN SYSTEMS: RESPIRATION
RESPIRATION:OXYGEN TO BREAK DOWN FOOD TO RELEASE ENERGY

SYSTEM:EXCHANGE OF GASES FOR CELL RESPIRATION
HUMAN SYSTEM INTERATIONS
NUTRIENTS FROM THE DIGESTIVE SYSTEM ARE TRANSPORTED TO CELLS BY CIRCULATORY

REPRODUCTIVE SYSTEM IS REGULATED BY HOROMONES FROM ENDOCRINE SYSTEM
SINGLE CELL VS. MULTICELLULAR
GAS EXCHANGE: CELL MEMBRANE + RESPIRATORY SYSTEM

TRANSPORT: CYTOPLASM + CIRCULATORY SYSTEM

NUTRITION: VACUOELS + DIGUESTIVE SYSTEM

EXCRETION: CELL MEMBRANE + EXCRETORY SYSTEM
PHOTOSYNTHESIS FORMULA
LICH=SOX

LIGHT + C02 + H2O = SUGAR + OXYGEN
RELEASING ENERGY
DECR
[DECK 'ER]

STARCH -> DIGESTION -> GLUCOSE -> ENZYMES -> SIMPLER GLUCOSE -> CELLULAR RESPIRATION -> EMERGY RELEASED -> ENERGY ALLOWS ADP -> ATP
CATAYLYST
ANY SUBSTANCE THAT CAN AFFEC TTHE RATE OF A CHEMICAL REATION WITHOUT ITSELF BEING CHANGED OR USED UP DURING THE REACTION
ENZYME REACTION RATES
SHAPE
TEMPERATURE
Ph LEVEL [ACID-> BASIC]
0->14
FEEDBACK MECHANISMS
POSITIVE [BABY CONTRACTIONS]

NEGATIVE [BLOOD SUGAR LEVEL]
PANCREAS SECRETES INSULIN TO LOWER & LIVER SECRETES GLUCOSE TO HIGHER
DISEASE & PATHOGENS
PATHOGENS-FOREIGN OBJECTS ENTER BODY WITH ANTIGENS ON MEMBRANE. ANTIGENS TRIGGER RESPONSE TO IMMUNE SYSTEM WITH SENDS ANTIBODIES TO DESTROY PATHOGEN. ANTIBODIES ARE LEFT TO REMEMBER THAT SPECIFIC PATHOGEN TO DEFEAT IT QUICKER IF IT COMES AGAIN. IN VACCINNES YOU ARE GIVEN A WEAKENED PATHOGEN.
