  1. 10-24-2012 • Objective: We will learn how hydrolysis and dehydration equations are written, that enzymes affect activation energy, and the difference between secretion and excretion. • Language Objective: I will explain dehydration, hydrolysis, activation energy, and the difference between excretion and secretion. • Homework: Draw a Venn diagram to compare and contrast Prokaryotic and Eukaryotic Cells

  2. Warm-Up • 1. How do amoebas move? False feet (psuedopods) • 2. What is the function of cilia? To aid in movement/locomotion • 3. What is the function of flagella? To aid in movement/locomotion • 4. Cells use passive and active transport to move materials across the cell membrane to maintain _____________________. • a. Diffusionb. evolution c. homeostasis d. respiration • 5. What type of solution was the egg on left placed in? • a. Hypertonic • b. Hypotonic • c. Isotonic

  3. Hydrolysis/Dehydration Hydrolysis or Dehydration?

  4. Hydrolysis/Dehydration Hydrolysis or Dehydration?

  5. Hydrolysis/Dehydration • Hydrolysis – adding water to a reaction • Dehydration – removing water from a reaction

  6. Enzymes – lower activation energy(SPEED UP A CHEMICAL REACTION)

  7. Benedict’s Solution • The most common use for Benedict Solution is the detection of glucose in urine for the diagnosis of diabetes.

  8. Excretion/Absorption/Secretion • Diabetics excrete glucose into their urine because they are unable to properly absorb it into their cells. After a positive diagnosis, additional tests are needed to quantify the amount of glucose excreted. • Excrete – it exits your body • Secretion – released within an organism (hormones) • Sugar = Glucose = Carbohydrate

  9. Excretion/Absorption/Secretion • Osmosis • Diffusion • Dehydration • Hydrolysis • Homeostasis • Enzymes • Hypotonic • Hypertonic DNA RNA Nucleotide (3 parts) Carbohydrates Centromere Centrioles Mitosis S Phase –Synthesis of DNA Cell Cycle Lytic Cycle (viruses) Bacteria Living organisms Cell membrane Prokaryote Eukaryote
