  1. Cellular biology A Review

  2. What is the smallest element of protoplasm? • The cell • Which of the following macromolecules contain enzymes for repair? A) protein b) lipids c) carbs d) nucleic acids

  3. _____provides most of the cell’s energy DNA and RNA are two types of these What is function of lipids Carbohydrates Nucleic acids store energy component of membrane protects against cold and heat assists in digestive process components of substances such as hormones MORE QUESTIONS

  4. Tissues are groups of ? Organs are groups of ? System is a group of? An organism is? Cells tissues organs a human

  5. CELLULAR ANATOMY • Ribosomes • Mitochondria • Endoplasmic Reticulum • Lysosomes • Golgi Apparatus

  6. RADIATION BIOLOGY CHAPTER 5..an introduction-What do you already know?

  7. DO YOU REMEMBER BERGONIE AND TRIBONDEAU? Pg 102 (Sherer)

  8. TWO TYPES OF CELLS • Somatic • Germ

  9. MALIGNANT CELLS • Divide abnormally • increased amount of chromatin • increased amount of nuclear material • normal cells stay together (tissue) • some malignant cells break away to other tissues

  10. Direct effect • Where do you think the radiation hits to be given this name?

  11. INDIRECT EFFECT • What molecule to you think radiation hits? • Most interactions occur here • Forms free radicals which are chemical components that damage cells • Free radicals are a result of radiolysis of water

  12. FRACTIONATION • Dividing a dose of radiation into small amounts over a given time

  13. PROTRACTED DOSE • Dose delivered continuously but at a lower rate
