 CATABOLISM

 THE DESTRUCTIVE METABOLISM, IS THE PROCESS
 THAT PRODUCE THE ENERGY REQUIRED FOR ALL
 ACTIVITIES IN THE CELLS.
 OCCURS IN THE CHLOROPLAST OF
 PHOTOSYNTHETIC PLANTS

 CHLOROPLAST: A MEMBRANE ENCLOSED
 ORGANELLE WHICH ALLOW PLANTS TO PRODUCE
 THEIR OWN ORGANIC FOOD
 CARBON DIOXIDE +WATER+
 ENERGY=GLUCOSE+OXYGEN

 CO2+H2O+ENERGY=C6 H12 06+O2


 OXIDATION-REDUCTION REACTIONS
THE CYCLING OF MOLECULES BETWEEN
CHLOROPLASTS AND MITOCHONDRIA ALLOW A
FLOW OF ENERGY FROM THE SUN THROUGH ALL
LIVIG THNGS
 ALSO KNOWN AS CONSRUCTION METABOLISM, IS
  ALL ABOUT BUILDING AND STORING
 IT SUPPORTS THE GROWTH OF NEW CELLS,THE
  MAINTENANCE OF BODY TISSUES AND THE
  STORAGE OF ENERGY FOR USE IN THE FUTURE
 DURING ANABOLISM, SMALL MOLECULES ARE
 CHANGED INTO LARGER, MORE COMPLEX
 MOLECULES OF CARBOHYDRATE, PROTEIN AND
 FAT
 CELLULAR RESPIRATION IS THE PROCESS BY
 WHICH THE CHEMICAL ENERGY OF “FOOD”
 MOLECULES IS RELEASED AND PARTIALLY
 CAPTURED IN THE FORM OF ATP
CARBOHYDRATES, FATS AND PROTEINS CAN ALL
BE USED AS FUELS IN CELLULAR RESPIRATION, BUT
GLUCOSE IS MOST COMMONLY USED AS AN
EXAMPLE TO EXAMINE THE REACTIONS AND
PATHWAYS INVOLVED.
 STEP WISE RELEASE OF ENERGY FROM
  MOLECULES LIE GLUCOSE, ACCOMPANIED BY THE
  USE OF THIS ENERGY TO SYNTHESIS ATP
  MOLECULES
 MITOCHODRIA IS A MEMBRANE ENCLOSED
  ORGANELLE THAT CONTAINE DNA, RIBOSOMES
  AND ENZYMES, SITE OF ATP PRODUCTION
 AS THE CELL PERFORMS ITS LIFE PROCESSES AND
 CONVERTS ABSORBED FOOD SUBSTANCE INTO NEW
 LIVING PROTOPLASM, IT INCREASES IN SIZE.
 AFTER ATTAINING A CERTAIN SIZE, IT DIVIDES
 A.) DIRECT CELL DIVISION OR AMITOSIS-
 UNICELLULAR ORGANISM UNDERGO DIRCET CELL
 DIVISION, WHERIN CONSTRICTION APPEARS ON
 THE PLASMA MEMBRANE WHICH DEEPENS AND
 DIVIDES BOTH CYTOPLASM AND NUCLEUS
 RESULTING INTO A DAUGHTER CELL
 (PROKARYOTIC cell)
B.) INDIRECT CELL DIVISION OR MITOSIS IS WHEN A
MULTICELLULAR ORGANISN UNDEGO INDIRECT
CELL DIVISION WHEREIN SEVERAL CHANGES TAKE
PLACE IN THE CELL PRIOR TO DIVISION
(EUKARYOTIC CELLS)
THE PROCESS OF CELLULAR DIVISION IS UNIQUE TO
 EUKARYOTIC CELLS

-IN BOTH PROCESSES, DNA WITHIN THE PARENT
  CELL IS DISTRIBUTED TO THHE DAUGHTER CELL

-46 CHROMOSOMES ,23 PAIRS.
CHROMOSOMES IS AN ORGANIZED STRUCTURE OF
 DNA AND PROTEIN THAT IS FOUND IN CELLS. IT IS
 A SINGLE PIECE COILED DNA CONTAINING MANY
 GENES, REGULATORY ELEMENTS AND OTHER
 NUCLEOTIDE SEQUENCES



- 1 PAIR OF CHROMOSOMES –DETERMINES THE
   INDIVIDUAL SEX

  FEMALE- XX
  MALE- XY
 PRODUCES TWO DAUGHTER CELLS, EACH WITH
 DNA THAT IS IDENTICAL TO THE DNA OF PARENT
 CELL
 TIME BETWEEN CELL DIVISIONS
 PROTEIN SYNTHESIS CARRIED OUT
 DNA FOUND AS THIN THREADS OF CHROMATIN IN
  THE NUCLEUS
 NUCLEOLUS PRESENT
 DNA REPLICATED TOWARDS DIVISION TIME
 METABOLIC CHANGES PREPARE THE CELL FOR
  DIVISION. AT A CERTAIN POINT-THE RESTRICTION
  POINT-THE CELL IS COMMITED TO DIVISION AND
  MOVES INTO THE S PHASE
 NO DNA SYNTHESIS OCCURS BUT RNA AND
  PROTEIN SYNTHESIS DO OCCUR
 EACH DAUGHTER CELL GROWS THE SIZE OF THE
  LONGEST AND MOST VARIABLE PHASE OF THE
  CELL CYCLE.
 FINAL PREPARATION FOR THE CELL DIVISION
  OCCURS DURING THIS PHASE
 FURTHER INCREASE IN CELL VOLUME AND
  SYNTHESIS OF ENZYME AND OTHER PROTEIN
 METABOLIC CHANGES ASSEMBLE THE
  CYTOPLASMIC MATERIALS NECESSARY FOR
  MITOSIS AND CYTOKINESIS
 A NUCLEAR DIVISION (MITOSIS) FOLLOWED BY A
 CELL DIVISION (CYTOKINESIS)
 CHROMATIN THICKEN INTO CHROMOSOMES
 NUCLEAR MEMBRANE DISINTEGRATES
 CENTRIOLE PAIRS MOVE TO OPPOSITE ENDS OF
  THE CELL
 SPINDLE FIBERS BEGIN TO FORM
 CHROMOSOMES COIL AND SHORTEN
 CHROMOSOMES HAS A PAIR OF CHROMATIDS
  CONNECTED BY CENTROMERE
 GUIDED BY THE SPINDLE FIBERS, THE
  CHROMOSOME PAIRS LINE UP ALONG THE CENTER
  OF THE SPINDLE STRUCTURE
 CHROMOSOMES LINE UP AT THE CENTER OF THE
  CELL, CENTROERES DIVIDE PULLING THE
  CHROMOSOMES APART
 THE CHROMOSOME PAIRS (SISTERS) BEGIN TO PULL
  APART. ONCE SPERATED THEY ARE CALLED
  DAUGHTER CHROMOSOMES.
 DUE TO PULL, MANY CHROMOSOMES BEND
 GROOVE IN PLASMA MEMBRANE PRESENT
 -SISTER CHROMATIDS ARE NOW TWO SEPARATE
  CHROMOSOMES
 CHROMOSOMES RETURN TO CHROMATIN
 SPINDLE DISINTEGRATES
 NUCLEAR MEMBRANE TAKES SHAPE AGAIN
 CENTRIOLES REPLICATE
 MEMBRANE CONTINUED TO PINCH INWARD
 THE FINAL CELLULAR DIVISION TO FORM TWO CELLS
 IN PLANTS A CELL PLATE FORMS ALONG THE LINE OF
 THE METAPHASE PLATE, IN ANIMALS THERE IS A
 CONSTRICTION OF THE CYTOPLASM

 THE CELL THEN ENTERS INTERPHASE-THE INTERVAL
 BETWEEN MITOTIC DIVISIONS
 WHEN THE PROCESS IS COMPLETE, EACH CELL
 WALL WILL HAVE THE SAME GENETIC MATERIAL
 THAT THE ORIGINAL CELL HAD BEFORE
 REPLICATION. WHEN THE PROCESS IS COMPLETE,
 EACH CELL WILL HAVE THE SAME GENETIC
 MATERIAL THAT THE ORIGINAL CELL HAD BEFORE
 REPLICATION. EACH OF THE DAUGHTER CELLS IS
 ALSO IDENTICAL TO EAH OTHER. NOTE THAT
 ONCE TELOPHASE IS COMPLETE, THE CELL
 RETURNS TO INTERPHASE
