7:33 PM I. Tour of the Cell
I.a. 2 cells don’t reproduce
I.a.i. Most neurons
I.a.ii. Skeletal muscles (too big to undergo mitosis)
I.a. Cells are complexi organized
I.a.i. Respond to stimuli
I.a. 3 necessary components for cells
I.a.i. Be able to accumulate energy from environment
I.a.ii. Information storage and retrieval system
I.a.iii. Boundary system to separate inside from outside
I.a. Prokaryotes
I.a.i. Form before the nucleus (no nucleaus, no internal membrane structure)
I.a.ii. Bacteria
I.a.i.1. Some are good
I.a.i.1.a. (E. Coli)
I.a.i.1.a.i. Waste produces vitamin K which helps blood clotting
I.a.i.1.a.ii. MreB
I.a.i.1.a.i.1. An actin in bodies, builds structure
I.a.i.1.a.i.1.1. Control protein, makes muscles move, found in all shapes bacteria and chromosomes shaped segregation
I.a.i.1. Bacteria Phages
I.a.i.1.a. Phages that attack bacteria, causes DNA from viruses to produce tubulin protein, to create more viruses
I.a.i.1. Has a cell wall. Pourous material made of 2 sugars
I.a.i.2. 3 amino acids linked known as a Peptide bridge
I.a.i. Cell Wall
I.a.i.1. Has Plasma membrane made of lipids, fats, proteins, attached to the cell, selectively permeable structure, keeps control of what gets in and out of the cell
I.a.i.2. Pushes membrane against cell wall
I.a.i.1.a. Messasome
I.a.i.1.a.i. Where ATP is formed, and cellular respiration
I.a.i. Structure of DNA in Prokaryoes is a circle 0
I.a.ii. Have plasmids
I.a.i.1. Genes for many things end upon plasmids. Can be exchanged with other material cells
I.a.i. Have Ribosomes
I.a.i.1. Where proteins are made and mRNA
I.a.i.2. Smaller than Eukaryotes Ribosomes (works the same)
I.a.i. Cytoskeleton in Prokaryotes and Eukaryotes
I.a.ii. Tubulin -protein that makes up microtubules
I.a.i.1. FstZ
I.a.i.1.a. Found in all Prokaryotes and in chloroplasts in plant cells
I.a.i.1.b. Used in cell division
