Toxic Death


What is toxic death?



● Oily sheen covering her body: fruity, garlicky odor that  thought was coming from her mouth

● Noticed upon drawing blood from her, the blood had a  chemical scent to it  

● Welch (one of the doctors on call that night) reported  her blood smelled like ammonia.

● Noticed unusual manilla colored particles floating in the blood

Note: Apnea is a condition in which someone stops breathing for  several seconds, takes a few breaths, then stops breathing again.

Cells

● The cell is the basic unit of living If you want to learn more check out How did the age of discovery begin?

● The simpler the cell, the greater it’s regeneration power and  the more specialized the cell, the weaker its power ● Cell Theory- states that the entire human (or animal or plant) is the aggression of living cells arranged to function


What is the function of the endoplasmic reticulum in a cell?



Basic Units of a cell  We also discuss several other topics like What are the qualifications of a scientific hypothesis?

● Nucleus 

● Protoplasm 

● Plasma membrane  

Protoplasm contains a high percentage of water, inorganic ions  (Potassium, magnesium, and calcium) and organic compounds  (proteins, lipids, and carbohydrates)  

Ribosomes are the sites of protein synthesis  

Mitochondria are threadlike structures within the cytoplasm that

provide most of the body’s adenosine triphosphate (an enzyme  that stores energy)  

Golgi Apparatus modifies concentrates (such as secretory  products) and is associated with formation of proteins and other  substances


What is the major function of histones?



We also discuss several other topics like What are the types of chemical process?
We also discuss several other topics like Does conceivability entail possibility?

Endoplasmic reticulum- extensive network of membrane enclosed tubules in the cytoplasm  

Rough ER - produces certain proteins

Smooth ER - produces lipids  If you want to learn more check out How many significant figures are in 2090.070?

Lysosomes- takes part in intracellular digestion  

Centrosomes- contains centrioles, which take part in cell division  

Inclusions- temporary: non functioning units; examples are the  stored nutrient glycogen in the liver cells and melanin in epithelial cells

Peroxisomes contain oxidases capable of reducing oxygen to  hydrogen peroxide and hydrogen peroxide to water

Cytoskeletal elements form a network of protein structures DNA 

● Found in the chromosomes of the cell

● Carries genetic information and provides the blueprint for  the protein synthesis

● Composed of two long, twisted chains of phosphate, sugar

molecules (deoxyribose), purines, and pyrimidines RNA We also discuss several other topics like What is dimensionless formula?

● Controls protein synthesis  

● Serves as the genetic material for many viruses (it is also  found in the cytoplasm)  

Cell division 

● Cells reproduce through division  

● Divide by mitosis and meiosis  

Dna Ligase fills in the gaps between the new stretches of DNA  formed” DNA ligases are very important in “fixing” breaks that  occur and thus prevent mismatched strands of DNA. DNA  polymerases can correct mismatched base pairs or replace  mutated ones.

Histones (protein) of chromatin RNA polymerase cause the  double helix of DNA to unwind (let’s simplify to histones cause the DNA molecule to unwind).

Despite the complexity of the process, each DNA polymerase  works at an impressive rate of about 100 base pairs per second  and there are thousands of polymerase molecules at work such  that all 46 chromosomes can be replicated in a mere 6 to 8 hours.

Nucleolus- a dark staining body within the nucleus that lacks  membrane and contains ribosomal RNA and proteins; produces  ribosomes

Plasma membrane is only 7 nm to 8 nm thick, has a

semipermeable membrane and has a double layer of  phospholipids with proteins molecules and serves as the cell’s  external boundary.  

Cell division 

● Cells reproduce through division  

● Divide by Mitosis and Meiosis  

Electrolytes- when ions become dissociated into charged  particles (with a+ and - charge)

Cytosol- viscous, semi transparent fluid consisting of 70% to 90% water; contains salts, sugars, and soluble proteins
