troops to respond to outside threats and facilitated trade and commerce. This system of roadways not only connected the empires but promoted the spread of ideas‚ like Christianity in the Roman Empire and Buddhism in China. Both empires were further linked by a network of cities that acted as a nerve system that helped to tie the empire together. The cities were centers of administration and customs emanated into the surrounding area fostering cultural diffusion even though only around twenty percent

25 The Urinary System: Urinary System Organs * Kidneys are major excretory organs * Urinary bladder is the temporary storage reservoir for urine * Ureters transport urine from the kidneys to the bladder * Urethra transports urine out of the body Kidney Functions * Removal of toxins‚ metabolic wastes‚ and excess ions from the blood * Regulation of blood volume‚ chemical composition‚ and pH Kidney Functions * Gluconeogenesis during prolonged fasting * Endocrine functions * Renin: regulation

Energy generated (4tps and 2 NADH) Stage 1 Step 1 – trapping glucose‚ glucose enters via facilitated diffusion through specific transport proteins. The family of transporters is known as GLUT‚ GLUT 3 (brain‚ nerve tissue) Low Km allows relatively constant rate of glucose uptake‚ GLUT 2 (liver‚ β-cells pancreas) high Km rate of uptake proportional to

Human Cell‚ protein production‚ cell organelles and the cell membrane. Structure and cell transport. The cell is the basic structural and functional unit of all known living organisms (See figure 1). It is the smallest unit of life that is classified as a living thing (except virus‚ which consists only from DNA/RNA covered by protein and lipids)‚ and is often called the building block of life. Organisms can be classified as unicellular (consisting of a single cell; including most bacteria) or

Unit 1: Biochemistry Review Chemical Bonding Three types of bonds Ionic bond: 2 oppositely charged atoms (Na and Cl) Polar covalent: Unequally shared electrons (H and O) Non polar covalent: Equally shared electrons (C and C) or similar electronegativity Electronegativity and chemical bonding Electronegativity is a measure of the strength in which an atom can attract electrons. A difference of < 0. 5 is non polar covalent bond A difference of 0.5 – 1.7 is polar covalent bond A difference of > 1
