BIOB10H3 Study Guide - Midterm Guide: Embryonic Stem Cell, Hydrogen Bond, Peptide Bond
Document Summary
Atoms make molecules, molecules make macromolecules, which make organelles, which a bunch of organelles make the cell, cells make up tissues, tissues make up organs, and they make an organisms. Proteins make cells specialized, they are the enzymes that do all the work. Robert hooke- defined the word cell first (said it looked like a cork) Anton van leeuwenhoek aminicules (paramecium) looking at pond water organisms (ie. he was the first to observe and describe microorganisms) Cell theory : all organisms are composed of one or more cells, cell is the basic unit of life, cells can only be formed by the divisions of a pre- existing cell. Plant diagram: (go over peroxisome, microtubules, difference between vacuole vs. vesicle, plasmodia) Proteasome = located in the nucleus and the cytoplasm, it degrades unneeded or damaged proteins by proteolysis (breaks peptide bonds) Cells are highly complex and organised (co,g,r,e, cr , s,e) (coger, cres)
