Chapter 7 Membrane Structure and Function Days8 Objectives -You will understand that membranes are fluid -The structure results in a semi-permeable membrane.
IS3 CELLS
Dr Gihan Gawish. Function Maintains homeostasis Removing metabolic waste (except CO2) – e.g. ammonia, urea, uric acid Removing foreign compounds – e.g.
Contains C, H, and O, generally with a 2:1 ratio of H to O (CH2O),provides much of the energy that the cell requires, include sugars and starches, can.
Osmosis and Diffusion!. IMPORTANT DEFINITIONS DIFFUSION : movement of particles from higher concentration to lower concentration DIFFUSION : movement.
CYTOLOGY THE STUDY OF CELLS - FUNCTION. CELLULAR ACTIVITIES Transport systems – Processes of Transport Across Cell Membrane The Cell Cycle – Cellular.
Transport VOCAB ONLY. An INTEGRAL MEMBRANE PROTEIN that moves molecules PASSIVELY across cell membranes by attaching, CHANGING SHAPE, and flipping to.
Passive Transport. Healthy Cell 70% water 15% protein 10% fat 4% DNA and other materials 1% carbohydrate.
Origin of Eukaryotes. Membrane Structure ● The plasma membrane separates the living cell from its nonliving surroundings. (a) Phospholipid bilayer of.
REGULATION - what does this word mean to you? Why? What? How? Set point = homeostasis.
DIGESTION ABSORPTION GI TRACT ANATOMY OF GI TRACT.
Movement through the cell: Molecules have to move around the cell to do their jobs. Sometimes they go into, or out of an organelle. Our cells use Diffusion.
