BIOL 100 Lecture Notes - Lecture 3: Aquaporin, Apoptosis, Nuclear Pore
Document Summary
Cells are saline-filled balloons enclosed by membranes with various receptors. Inside the cell there are multiple chem reactions that maintain and trigger various functions of the cell. Each cell has a number of organelles that control atp production/reproduction. The cell is the basic unit of life. Cells form tissues, tissues form organs, muscle cells make up tissue but not organs. Red blood cell: cells that transport oxygen & co2 b/w lungs & tissues. Organ systems are the nervous, skeletal, digestive, cardiovascular, respiratory, endocrine, immune, muscular & integumentary (skin). Neuron = cell for the nervous system. The cell cannot survive without a system to bring food & oxygen. Communicates with other cells through blood & electrical signals. The cell"s barrier is the plasma membrane - made up of a phospholipid layer w/ a negative electrical charge on the inside & positive on the outside.
