BIOL 141 Lecture Notes - Lecture 1: Endoplasmic Reticulum, Lipid Bilayer, Lysozyme
Document Summary
Cell membrane: the cell membrane consists of two layers made of lipids, which is called the lipid bilayer, lipids are organic compounds, essentially fatty acids, the membrane also includes other components, such as proteins and carbohydrates. Dna in a cell"s nucleus: instructions are in the dna which are in a cell"s nucleus, ions generate electric signals by moving in and out of the nerve cells. Similar to a malfunctioning phone or device that was incorrectly built. Mitochondria: the mitochondria is the powerhouse of the cell; the primary place where cells get energy. This energy is called adenosine triphosphate, better known simply as atp: oxygen is a necessity to producing atp. Smooth endoplasmic reticulum: the smooth endoplasmic reticulum"s function is storage, it stores calcium, calcium is used as a messenger inside a cell that turns quetarny proteins on and off. Mitosis: mitosis is cell division, in which two identical cells are made, having the same kind and number of chromosomes.
