Document Summary
Lecture 3: centrioles a pair of centrioles is located near the nucleus. Position at right angles to each other polysinglarous. Formula/ construction: 9 triplets + 0 (like basal body) Function in the formation of cilia & flagella. Constructed of protein & 2 r-rna molecules. The site of protein synthesis including enzymes. Enzymes are chemicals that facilitate all the chemical reactions in the body. The key" which allows certain chemical reactions to occur. They are membranous channels with vesicles (sacs) & tubules that serve as an internal transport system for proteins & others molecules. Types of endoplasmic reticuli (er: rough e. r. Covered with ribosomes; the transported proteins are likely synthesized by the ribosomes on the e. r: smooth e. r. Not associated with ribosomes and is thought to be the site of lipid synthesis (ex. cholesterol including hormones such as steroids) as well as serving as a site for fat breakdown into small molecules.
