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.
