Biology And Biomedical Sciences BIOL 2960 Lecture Notes - Lecture 1: Nucleoplasm, Ketone, Cellular Respiration
Document Summary
22-29 january 2016: living organisms and cells, characteristics of living organisms, common characteristics of living organisms, they obtain raw materials and energy from the environment. Interior of the cell is separated from its environment. The inside of the cell is chemically different from the environment, and this accommodates the biochemistry of life: there are 2 basic types of cells. Prokaryotes (archaea and bacteria) have non-compartmentalized structures. Eukaryotes have processes compartmentalized processes in membrane bound organelles: prokaryotic cells vs. eukaryotic cells, the prokaryotic cell, know how to label and describe the functions of the following: Plasma membrane- separates cell from environment, regulates passage in/out of cell. Cytoplasm- mostly water, contains several important biomolecules, where most of metabolism occurs. Nucleoid- region where the genetic information (dna) is contained. Ribosomes- structures of rna and proteins that are involved in protein synthesis. The green is the cell wall, cell membrane, and a flagellum.
